Important:

• All documents and any examples they contain are provided as-is and are subject to change without notice.

Except to the extent prohibited by law, Libelium makes no express or implied representation or warranty of any kind with regard to the documents, and specifically disclaims the implied warranties and conditions of merchantability and fitness for a particular purpose.

• The information on Libelium’s websites has been included in good faith for general informational purposes only. It should not be relied upon for any specific purpose and no representation or warranty is given as to its accuracy or completeness.

2.1. General and safety information

• In this section, the term “Waspmote” encompasses both the Waspmote device itself and its modules and sensor boards.

• Please read carefully through the document “General Conditions of Libelium Sale and Use”.

• Do not let the electronic parts come into contact with any steel elements, to avoid injuries and burns.

• NEVER submerge the device in any liquid.

• Keep the device in a dry place and away from any liquids that might spill.

• Waspmote contains electronic components that are highly sensitive and can be accessed from outside; handle the device with great care and avoid hitting or scratching any of the surfaces.

• Check the product specifications section for the maximum allowed power voltage and amperage range and always use current transformers and batteries that work within that range. Libelium will not be responsible for any malfunctions caused by using the device with any batteries, power supplies or chargers other than those supplied by Libelium.

• Keep the device within the range of temperatures stated in the specifications section.

• Do not connect or power the device with damaged cables or batteries.

• Place the device in a location that can only be accessed by maintenance operatives (restricted area).

• In any case, keep children away from the device at all times.

• If there is an electrical failure, disconnect the main switch immediately and disconnect the battery or any other power supply that is being used.

• If using a car lighter as a power supply, be sure to respect the voltage and current levels specified in the

“Power Supplies” section.

• When using a battery as the power supply, whether in combination with a solar panel or not, be sure to use the voltage and current levels specified in the “Power supplies” section.

• If a software or hardware failure occurs, consult the Libelium Web Development section

• Check that the frequencies and power levels of the radio communication modules and the integrated antennas are appropriate for the location in which you intend to use the device.

• The Waspmote device should be mounted in a protective enclosure, to protect it from environmental conditions such as light, dust, humidity or sudden changes in temperature. The board should not be definitively installed “as is”, because the electronic components would be left exposed to the open-air and could become damaged. For a ready-to-install product, we advise our Plug & Sense! line.

DO NOT TRY TO RECHARGE THE NON-RECHARGEABLE BATTERY, IT MAY EXPLODE AND CAUSE INJURIES

AND DESTROY THE EQUIPMENT. USE NON-RECHARGEABLE BATTERIES ONLY WITH DEVICES PROPERLY

PREPARED. PLEASE DOUBLE CHECK THIS CONDITION BEFORE CONNECTING THE USB OR THE SOLAR

PANEL.

2.2. Conditions of use

General:

• Read the “General and Safety Information” section carefully and keep the manual for future reference.

• Read carefully the “General Conditions of Sale and Use of Libelium”. This document can be found at: http://www.libelium.com/development/waspmote/technical_service . As specified in the Warranty docu ment, the client has 7 days from the day the order is received to detect any failure and report that to Libelium. Any other failure reported after these 7 days may not be considered under warranty.

• Use Waspmote in accordance with the electrical specifications and in the environments described in the

“Electrical Data” section of this manual.

• Waspmote and its components and modules are supplied as electronic boards to be integrated within a fi nal product. This product must have an enclosure to protect it from dust, humidity and other environmental interactions. If the product is to be used outside, the enclosure must have an IP-65 rating, at the minimum.

For a ready-to-install product, we advise our Plug & Sense! line.

• Do not place Waspmote in contact with metallic surfaces; they could cause short-circuits which will permanently damage it.

Specific:

• Buttons and switches: Handle with care, do not force activation or use tools (pliers, screwdrivers, etc) to handle it.

• Battery: Only use the original lithium battery provided with Waspmote. Connect with extreme care.

• Mini-USB connection: Only use mini-USB, mod. B, compatible cables.

• Solar panel connection: Only use the solar panels specified in the “Power supplies” section and always res pect polarity.

• Lithium battery connection: Only use the connector specified in the “Battery” section and always respect polarity.

• Micro SD card connection: There are many SD card models; any of them has defective blocks, which are ignored when using the Waspmote’s SD library. However, when using OTA, those SD blocks cannot be avoided, so that the execution could crash. Libelium implements a special process to ensure the SD cards we provide will work fine with OTA. The only SD cards that Libelium can assure that work correctly with Wasp mote are the SD cards we distribute officially.

• Micro SD card: Make sure Waspmote is switched off before inserting or removing the SD card. Otherwise, the SD card could be damaged.

• Micro SD card: Waspmote must not be switched off or reseted while there are ongoing read or write opera tions in the SD card. Otherwise, the SD card could be damaged and data could be lost.

• XBee module connection: Waspmote allows the connection of any module from the XBee family, respect polarity when connecting (see print).

• Other modules connection: Only use the original modules created by Libelium.

• Antenna connections: Each of the antennas that can be connected to Waspmote (or to its boards) must be connected using the correct type of antenna and connector in each case, or using the correct adapters.

• USB voltage adapters: To power and charge the Waspmote battery, use only the original accessories distributed by Libelium.

-8v8.2

Waspmote Kit

Usage and storage recommendations for the batteries:

The rechargeable, ion-lithium batteries, like the ones provided by Libelium (capacity of 6600 mA·h), have certain characteristics which must be taken into account:

• Charge the batteries for 24 hours before a deployment. The aim is to have the charge of the batteries at

100% of their capacity before a long period in which they must supply current, but it is not necessary to improve the performance.

• It is not advised to let the charge of the batteries go below 20% of capacity, since they suffer stress. Thus, it is not advised to wait for the battery to be at 0% to charge it.

• Any battery self-discharges: connected to Waspmote or not, the battery loses charges by itself.

• Maximum capacity loss: as the charge and discharge cycles happen, the maximum charge capacity is reduced.

• Batteries work better in cool environments: their performance is better at 10 ºC than at 30 ºC.

• At temperatures below 0 ºC, batteries can supply current (discharge), but the charge process cannot be done. In particular:

discharge range = [-20, 60] ºC

charge range = [0, 45] ºC

Only use the non-rechargeable batteries with the Waspmote units specifically prepared for them (identified with a pink sticker on them). The reason is, a regular Waspmote will try to inject current in the non-rechargeable battery if the USB or the solar panel is connected. This is dangerous for the good working of a non-rechargeable battery.

It could be damaged or even damage Waspmote.

Plug & Sense! line:

Libelium may provide the nodes with enclosures which are suitable to operate outdoors. The user, as final installer, must take great care when handling the product. We advise to read the Plug & Sense! Technical Guide to enlarge the life of your devices.

Remember that inappropriate use or handling of Waspmote will immediately invalidate the warranty.

There are some defined configurations of Waspmote Plug & Sense! depending on which sensors are going to be used. Waspmote Plug & Sense! configurations allow to connect up to six sensor probes at the same time.

Each model takes a different conditioning circuit to enable the sensor integration. For this reason each model allows to connect just its specific sensors.

This section describes each model configuration in detail, showing the sensors which can be used in each case and how to connect them to Waspmote. In many cases, the sensor sockets accept the connection of more than one sensor probe. See the compatibility table for each model configuration to choose the best probe combination for the application.

It is very important to remark that each socket is designed only for one specific sensor, so they are not interchangeable . Always be sure you connected probes in the right socket, otherwise they can be damaged.

Calibrated gas sensors are manufactured once the order has been placed to ensure maximum durability of the calibration feature. The manufacturing process and delivery may take from 4 to 6 weeks. The lifetime of calibrated gas sensors is 6 months working at maximum accuracy. We strongly encourage our customers to buy extra gas sensors to replace the original ones after that time to ensure maximum accuracy and performance.

4.5.1. Analog pins

Waspmote has 7 accessible analog inputs in the sensor connector. Each input is directly connected to the microcontroller. The microcontroller uses a 10-bit successive approximation analog to digital converter ( ADC ).

The reference voltage value for the inputs is 0 V (GND). The maximum value of input voltage is 3.3 V which corresponds with the microcontroller’s general power voltage.

To obtain input values, the function analogRead(analog input) is used, the function’s input parameter will be the name of the input to be read “ ANALOG1, ANALOG2… ” (see sensor connector figure). The value obtained from this function will be an integer number between 0 and 1023 , 0 corresponds to 0 V and 1023 to 3.3 V.

The analog input pins can also be used as digital input/output pins. If these pins are going to be used as digital ones, the following correspondence list for pin names must be taken into account:

Analog pin Digital pin

ANALOG1 => 14

ANALOG2 => 15

ANALOG3 => 16

ANALOG4 => 17

ANALOG5 => 18

ANALOG6 => 19

ANALOG7 => 20

{

val = analogRead(ANALOG1);

}

4.5.2. Digital pins

Waspmote has digital pins which can be configured as input or output depending on the needs of the application.

The voltage values corresponding to the different digital values would be:

• LOW: 0 V for logic 0

• HIGH: 3.3 V for logic 1

The instructions for control of digital pins are:

{

// set DIGITAL3 pin as input and read its value

pinMode(DIGITAL3, INPUT);

val = digitalRead(DIGITAL3);

// set DIGITAL3 pin as output and set it LOW

pinMode(DIGITAL3 ,OUTPUT);

digitalWrite(DIGITAL3, LOW);

}

4.5.3. PWM

DIGITAL1 pin can also be used as output PWM (Pulse Width Modulation) with which an analog signal can be

“simulated”. It is actually a square wave between 0 V and 3.3 V for which the proportion of time when the signal is high can be changed (its working cycle) from 0% to 100%, simulating a voltage of 0 V (0%) to 3.3 V (100%).The resolution is 8 bit , so up to 255 values between 0-100% can be configured. The instruction to control the PWM output is analogWrite(DIGITAL1, value); where value is the analog value (0-255).

{

analogWrite(DIGITAL1, 127);

}

-60v8.2

Hardware

4.5.4. UART

There are 2 UARTs in Waspmote: UART0 and UART1. Besides, there are several ports which might be connected to these UARTs through 2 different multiplexers, one for each UART.

• UART0 is shared by the USB port and the Socket0. This socket is used for XBee modules, LoRaWAN module,

LoRa module, Sigfox module, RFID/NFC module, Bluetooth modules, WiFi module, RS-485 module, etc. The multiplexer in this UART controls the data signal which by default is always switched to Socket0. When the

USB needs to send info through the UART0, the multiplexer is momentarily switched to the USB port and set back again to Socket0 after printing.

• UART1 is shared by 4 ports: Socket1, GPS socket, Auxiliar1 and Auxiliar2 sockets. It is possible to select in the same program which of the 4 ports is connected to UART1 in the microcontroller. UART1 multiplexer configuration is carried out using the following instructions:

{

Utils.setMuxAux1(); // set Auxiliar1 socket

Utils.setMuxAux2(); // set Auxiliar2 socket

Utils.setMuxGPS(); // set GPS socket

Utils.setMuxSocket1(); // set Socket1

}

4.5.5. I2C

The I2C communication bus is also used in Waspmote where several devices are connected in parallel: the accelerometer, a crypto-authentication memory and the RTC. In all cases, the microcontroller acts as master while the other devices connected to the bus are slaves.

4.5.6. SPI

The SPI port on the microcontroller is used for communication with the micro SD card. All operations using the bus are performed clearly by the specific library. The SPI port is also available in the SPI/UART connector and Socket0.

4.5.7. USB

USB is used in Waspmote for communication with a computer or compatible USB devices. This communication allows the microcontroller’s program to be loaded.

For USB communication, microcontroller’s UART0 is used. The FT232RL chip carries out the conversion to USB standard.

4.6. Real Time Clock - RTC

Waspmote has a built in Real Time Clock – RTC, which keeps it informed of the time. This allows Waspmote to be programmed to perform time-related actions such as:

“Sleep for 1h 20 min and 15sec, then wake up and perform the following action..”

Or even programs to perform actions at absolute intervals, e.g.:

“Wake on the 5th of next month at 00:20 and perform the following action..”

All RTC programming and control is done through the I2C bus.

Alarms:

Alarms can be programmed in the RTC specifying day/hour/minute/second. That allows total control about when the mote wakes up to capture sensor values and perform actions programmed on it. This allows Waspmote to be in the saving energy modes ( Deep Sleep and Hibernate ) and makes it wake up just at the required moment.

-61v8.2

Hardware

As well as relative alarms, periodic alarms can be programmed by giving a time measurement, so that Waspmote reprograms its alarm automatically each time one event is triggered.

The RTC chosen is the Maxim DS1337C , which operates at a frequency of 32.768 kHz (a second divisor value which allows it to quantify and calculate time variations with high precision).

The RTC is powered by the battery. When the battery is connected, the RTC is powered on. However, the user must keep in mind that if the battery is removed or out of load, then time data will be not maintained. This is the reason we suggest to use RTC time as ‘relative’ and not ‘absolute’ (see Programming Guide for more info).

A coin or button battery is not needed. They have a limited life and therefore Waspmote can have a much longer power life expectancy. This is so because the RTC is powered from the “main” battery which has a much bigger charge.

The RTC is responsible for waking Waspmote up from sleep modes like Deep Sleep and Hibernate . This makes possible to use its battery to just power the RTC in sleep modes. The RTC controls when the device has to wake up and perform a particular action. This permits a consumption of 7 uA in the Hibernate mode. Please refer to

“Energy System” section for more information.

4.7. LEDs

Figure: Visual indicator LEDs

The Waspmote LEDs are:

• Charging battery LED indicator: A red LED indicating that there is a battery connected in Waspmote which is being charged. The charging can be done through a mini-USB cable or through a solar panel connected to

Waspmote. Once the battery is completely charged, the LED switches off automatically.

• LED0 (programmable LED): A green LED is connected to the microcontroller. It is totally programmable by the user from the program code. In addition, the LED0 indicates when Waspmote resets, blinking each time a reset on the board is carried out.

• LED1 (programmable LED): A red LED is connected to the microcontroller. It is totally programmable by the user from the program code.

• USB Power LED indicator: A green LED which indicates when Waspmote is connected to a compatible USB port either for battery charging or programming. When the LED is on, it indicates that the USB cable is connected correctly. When the USB cable is removed, this LED will switch off automatically.

Please refer to Waspmote Utilities guide for more information.

-63v8.2

Architecture and system

5. Architecture and system

5.1. Concepts

The Waspmote’s architecture is based on the Atmel ATmega1281 microcontroller.

When Waspmote is connected and starts the bootloader , there is a waiting time (62.5 ms) before beginning the first instruction, this time is used to start loading new compiled programs updates. If a new program is received from the USB during this time, it will be loaded into the FLASH memory (128 kB) substituting already existing programs. Otherwise, if a new program is not received, the last program stored in the memory will start running.

The structure of the codes is divided into 2 basic parts: setup and loop . Both parts of the code have sequential behaviour, executing instructions in the set order.

The setup is the first part of the code, which is only run once when the code is initialized. In this part it is recommended to include the initialization of the modules which are going to be used, as well as the part of the code which is only important when Waspmote is started.

The part named loop runs continuously, forming an infinite loop. Because of the behavior of this part of the code, the use of interruptions is recommended to perform actions with Waspmote.

A common programming technique to save energy would be based on blocking the program (either keeping the micro awake or asleep in particular cases) until any of the interruptions available in Waspmote show that an event has occurred. This way, when an interruption is detected the associated function, which was previously stored in an interruption vector, is executed.

To be able to detect the capture of interruptions during the execution of the code, a series of flags have been created and will be activated to indicate the event which has generated the interruption (see chapters “Interruptions” and

“Energy system”).

Figure: Blocking loop, interruption appears and is dealt with

When Waspmote is reset or switched on, the code starts again from the setup function and then the loop function.

By default, variable values declared in the code and modified in execution will be lost when a reset occurs or there is no battery. To store values permanently, it is necessary to use the microcontroller’s EEPROM (4 kB) non-volatile memory. EEPROM addresses from 0 to 1023 are used by Waspmote to save important data, so they must not be over-written. Thus, the available storage addresses go from 1024 to 4095. Another option is to make use of the

SD card .

-64v8.2

Architecture and system

5.2. Timers

Waspmote uses a quartz oscillator which works at a frequency of 14.7456 MHz as a system clock. In this way, every

125ns the microcontroller runs a low level (machine language) instruction. It must be taken into account that each line of C++ code of a program compiled by Waspmote includes several instructions in machine language.

Waspmote is a device prepared for operation in adverse conditions with regards to noise and electromagnetic contamination, for this reason, to ensure stable communication at all times with the different modules connected through a serial line to the UARTs (communication modules and USB) a maximum transmission speed of 115200 bps has been set for the communication modules and the USB port, and 4800 for the GPS, so that the success rate in received bits is 100%.

5.2.1. Watchdog

The ATmega1281 microcontroller has an internal Enhanced Watchdog Time – WDT. The WDT precisely counts the clock cycles generated by a 128 kHz oscillator . The WDT generates an interruption signal when the counter reaches the set value. This interruption signal can be used to wake the microcontroller from the Sleep mode or to generate an internal alarm when it is running in on mode, which is very useful when developing programs with timed interruptions.

The WDT allows the microcontroller to wake up from a low consumption Sleep mode by generating an interruption.

For this reason, this clock is used as a time-based alarm associated with the microcontroller’s Sleep mode. This allows very precise control of small time intervals: 16 ms, 32 ms, 64 ms, 128 ms, 256 ms, 500 ms, 1 s, 2 s, 4 s, 8 s . For intervals over 8 s (Deep Sleep mode), the RTC is used and not the microcontroller.

More information about the interruptions generated by the Watchdog can be found in the “Energy system” chapter.

, WaspPWR.cpp

All information about their programming and operation can be found in the Interrupt Programming Guide .

All the documentation is located in the Development section in the Libelium website.

5.2.2. RTC Watchdog for reseting Waspmote

One of the alarms of the RTC (Alarm 2) is connected to a Watchdog reset circuit that is able to reset the microcontroller of Waspmote when the alarm is generated. This Watchdog has been implemented for reseting Waspmote if it gets stuck. That periodical reset avoids erratic behaviour. This is highly recommended for applications that need to be very robust and can never stop working. The use of the Watchdog feature enssures us that our Waspmote will never stop working.

The Watchdog feature requires the physical watchdog switch to be put in “enable” position.

Architecture and system

5.2.3. RTC

As shown in the “Hardware” chapter, Waspmote has a real time clock (RTC) running a 32.786 kHz which allows to set an absolute time.

Alarms can be programmed in the RTC specifying day/hour/minute/second. This allows total control when the mote wakes up to capture values and perform actions programmed on it. Also, the RTC allows Waspmote to function in the maximum energy saving modes ( Deep Sleep and Hibernate ) and to wake up just at the required moment.

The RTC allows the microcontroller to be woken from a low consumption state by generating an interruption. For this reason, it has been associated to the microcontroller’s Deep Sleep and Hibernate modes, making it possible to put the microcontroller to sleep, and wake it up by activating an alarm in the RTC. Sleeping intervals can go from

1 s to minutes, hours or even days.

More information about the interruptions generated by the RTC and Deep Sleep and Hibernate modes can be found in the “Energy system” chapter.

Interruptions

6. Interruptions

Interruptions are signals received by the microcontroller which indicate it must stop the task it is doing to handle an event that has just happened. Interruption control frees the microcontroller from having to control sensors all the time. It also makes the sensors warn Waspmote when a determined value (threshold) is reached.

Figure: Diagram of mode in Waspmote

Waspmote is designed to work with 2 types of interruptions: Synchronous and asynchronous:

• Synchronous interruptions: They are scheduled by timers. They allow to program when we want them to be triggered. There are 2 types of timer alarms: periodic and relative.

Periodic alarms are those to which we specify a particular moment in the future, for example: “Alarm programmed for every 4 th day of the month at 00:01 and 11 seconds”. They are controlled by the RTC.

Relative alarms are programmed taking into account the current moment, eg: “Alarm programmed for 5 minutes and 10 seconds”. They are controlled through the RTC and the microcontroller’s internal

Watchdog.

• Asynchronous Interruptions: These are not scheduled, so it is not known when they will be triggered.

Types:

Sensors: The sensor boards can be programmed so that an alarm is triggered when a sensor reaches a certain threshold.

Accelerometer: Waspmote’s accelerometer can be programmed so that certain events such (as a fall or change of direction) generate an interruption.

All interruptions, both synchronous and asynchronous can wake Waspmote up from the Sleep and the Deep

Sleep modes. However, only the synchronous interruption by the RTC is able to wake it up from the Hibernate mode.

The Hibernate mode totally disconnects the Waspmote power, leaving only the battery powering the RTC to wake Waspmote up when the time alarm is reached. Because of this disconnection, when the RTC generates the corresponding alarm, the power in Waspmote is reconnected and the code starts again from the setup.

The way of detecting whether a reboot from the Hibernate mode has happened is to check whether the corresponding flag has been activated. The activation of this flag happens when the ifHibernate() function is called, which must be done at the beginning of the setup part of the code. This way, when Waspmote starts, it tests if it is a normal start or if it is a start from the Hibernate mode.

All information about the programming and operation of interruptions can be found in the Interruption

Programming Guide.

Energy system

7. Energy system

7.1. Concepts

Waspmote has 4 operational modes:

• On: Normal operation mode. Consumption in this state is 17 mA .

• Sleep: The main program is paused, the microcontroller passes to a latent state, from which it can be woken up by all asynchronous interruptions and by the synchronous interruption generated by the Watchdog. The duration interval of this state is from 32 ms to 8 s . Consumption in this state is 30 μA .

• Deep Sleep: The main program pauses, the microcontroller passes to a latent state from which it can be woken up by all asynchronous interruptions and by the synchronous interruption triggered by the RTC. The interval of this cycle can be from seconds to minutes, hours, days . Consumption in this state is 33 μA .

• Hibernate: The main program stops, the microcontroller and all the Waspmote modules are completely disconnected. The only way to reactivate the device is through the previously programmed alarm in the RTC

(synchronous interrupt). The interval of this cycle can be from seconds to minutes, hours, days . Almost all devices are totally disconnected from the battery: only the RTC is powered through the battery, from which it consumes 7 μA .

On the other hand, each module (radio, sensor board, etc) might have up to several operation modes.

• On: Normal operation mode.

• Sleep: Some communication modules permit to set up sleep modes so as to save energy (depends on each module).

• Off: By using Waspmote’s digital switches (controlled by the microcontroller), the module is switched off completely. This mode has been implemented by Libelium as an independent layer of energy control , so that it can reduce consumption to a minimum ( ~7 μA ) without relegating to techniques implemented by the manufacturer.

For complete information about interruption types and their handling, see the “Interruption” chapter.

All information about the programming and operation of interruptions can be found in the Interrupt Programming

Note: Before setting Waspmote to a low-power consumption mode, it is always recommended to switch any communication module off.

-68v8.2

Energy system

7.2. Sleep mode

In this mode, the main program is paused, the microcontroller passes to a latent state, from which it can be woken by all asynchronous interruptions and by the synchronous interruption generated by the Watchdog. When the

Watchdog Timer is set up, the duration interval can be programmed from 16 ms to 8 s . Consumption in this state is 30 μA .

In this mode the microcontroller stops executing the main program. The program stack where all the variables and log values are stored keep their value, so when Waspmote returns to on mode, the next instruction is executed and the variable values are maintained.

Figure: From on to Sleep mode

The following example would set Waspmote in the Sleep mode for 32 ms. The microcontroller would be in a state of minimum consumption waiting for the synchronous interruption from the Watchdog:

{

PWR.sleep(WTD_32MS, ALL_OFF);

}

-69v8.2

Energy system

7.3. Deep Sleep mode

In this mode, the main program is paused, the microcontroller passes to a latent state from which it can be woken by all the asynchronous interruptions and by the synchronous interruption launched by the RTC. The interval of this cycle can go from seconds to minutes, hours, days . Consumption in this state is 33 μA .

Figure: From on to Deep Sleep mode

7.4. Hibernate mode

In this mode, the main program stops, the microcontroller and all the modules are completely disconnected.

The only way to reactivate the device is through the previously programmed alarm in the RTC (synchronous interrupt). The interval for this cycle can go from seconds to minutes, hours or days . Almost all devices are totally disconnected from the battery: only the RTC is powered through the battery, from which it consumes 7μA .

In this mode the microcontroller does not store any values from variables or from the program stack. When leaving the Hibernate state the microcontroller is reset, so the setup and loop routines are run as if the main switch were activated.

Figure: From on to Hibernate mode

-70v8.2

Energy system

The Hibernate mode requires the physical Waspmote’s hibernate switch to be put in “enable” position. It is necessary to follow the next steps when executing the program for the first time after uploading it to Waspmote:

1. Connect the battery.

2. Switch Waspmote on.

3. Wait for the red LED to light on and turn the hibernate switch to the “enable” position while the red LED is on.

4. Once the hibernate switch is in the “enable” position, the green LED must blink to indicate that the program is running.

The following example would set Waspmote in the Hibernate mode for 2 days, 1 hour and 30 minutes. The microcontroller would be switched off waiting for the RTC to switch the device on again with a synchronous interruption.

{

PWR.hibernate(“02:01:30:00”, RTC_OFFSET, RTC_ALM1_MODE2);

8. Sensors

8.1. Accelerometer

Waspmote has a built-in acceleration sensor LIS3331LDH, by STMicroelectronics, which informs the mote of acceleration variations experienced on each one of the 3 axes (X,Y, Z).

The integration of this sensor allows the measurement of acceleration on the 3 axes (X, Y, Z), establishing 4 kinds of events: Free Fall, inertial wake up, 6D movement and 6D position which are explained in the Interruption

Programming Guide .

The LIS331DLH has dynamically user-selectable full scales of ±2g/±4g/±8g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz .

The device features ultra low-power operational modes that allow advanced power saving and smart sleep to wake-up functions.

The accelerometer has several power modes, the output data rate (ODR) will depend on the power mode selected.

The power modes and output data rates are shown in this table:

This accelerometer has an auto-test capability that allows the user to check the functioning of the sensor in the final application. Its operational temperature range is between -40 ºC and +85 ºC.

The accelerometer communicates with the microcontroller through the I2C interface. The pins that are used for this task are the SCL pin and the SDA pin, as well as another interruption pin to generate the interruptions.

-72v8.2

Sensors

The accelerometer has 4 types of event which can generate an interrupt: free fall, inertial wake up, 6D movement and 6D position.

These thresholds and times are set in the WaspACC.h file.

8.2. Integration of new sensors

The Waspmote design is prepared for the integration of both input (sensors) and output (actuators) which allows to grow the wide range of existing Waspmote sensor boards. The new sensors can be connected to Waspmote’s

2x12 and 1x12 pin connectors, which permit to use 16 input and output signals, 7 of which can be used as analog inputs and 1 as a PWM (Pulse Width Modulation) output signal. Besides, there is a line to ground, 3.3 V and 5 V power feeds, 2 selectable connections to the serial communication (UART) inputs and outputs, connection to the

2 lines of the (I2C) SCL and SDA Inter-Integrated Circuit bus, and connection to inputs for high level and low level interrupt. An image of the Waspmote output connectors can be seen in the “I/O” section.

The management the 2 power lines (3.3 and 5 V) for the sensor boards (described in more depth in section

”Sensors” → Power) is carried out through 2 solid state switches which allow the continuous flow of a current of up to 200 mA and whose control can be programmed using the functions included in the WaspPWR library, described in the files WaspPWR.h and WaspPWR.cpp

The input and output voltage values for both digital and analog pins will be between 0 V and 3.3 V, logic zero ( ‘0’ ) being found in values less than 0.5 V and logic one ( ‘1’ ) in values higher than 2.30 V . To read analog signals, the microcontroller has a 10-bit analog-to-digital converter which allows a resolution of 3 mV. Waspmote also has one

8-bit resolution PWM output pin for the generation of analog signals. Information on the libraries and instructions used for reading and writing on these pins can be found in the API manual.

Waspmote includes 2 interruption pins, a low level ( TXD1 ) one and a high level ( RXD1 ) one, which offer an alternative to reading the sensors by survey, allowing the microcontroller to be woken up when an event occurs

(such as exceeding a certain threshold in a comparator) which generates a change in a digital signal connected to one of the above pins, facilitating the sensor reading only at the moments when a remarkable event occurs.

This option is especially recommended for low consumption sensors that may remain active for long periods of time. Reading by survey (switched on and cyclical sensor reading after a set time) is more appropriate for those that, in addition to showing greater consumption, do not require monitoring that generates an alarm signal.

The interruptions can be managed using the warning functions and vectors (flags) defined in the Winterruptions library, file Winterruptions.c. More can be learnt about their use in the Interruption Programming Guide .

Sensors reading can generate 3 types of response: storage of collected data (on the SD card), wireless transmission of data (via wireless module) or automatic activation through an actuator directly controlled by the microcontroller’s output signals or through a switch or relay.

The XBee-PRO 802.15.4 modules comply with the standard IEEE 802.15.4 which defines the physical level and the link level (MAC layer). The XBee modules add certain functionalities to those contributed by the standard, such as:

• Node discovery: certain information has been added to the packet headers so that they can discover other nodes on the same network. It allows a node discovery message to be sent, so that the rest of the network nodes respond indicating their data (Node Identifier, @MAC, @16 bits, RSSI).

• Duplicated packet detection: This functionality is not set out in the standard and is added by the XBee modules.

The classic topology of this type of network is a star topology, as the nodes establish point to point connections with brother nodes through the use of parameters such as the MAC or network address.

The XBee-PRO 802.15.4 modules can use an optional firmware called DigiMesh . So the modules can create mesh networks instead of the usual point-to-point topology. This firmware has been developed by Digi in order to allow the modules to sleep, synchronize themselves and work on equal terms, avoiding the use of node routers or coordinators that have to be permanently powered on. Characteristics of the implemented protocol:

• Self healing: any node can join or leave the network at any moment.

• All nodes are equal: there are no father-son relationships.

• Silent protocol: reduced routing heading due to using a reactive protocol similar to AODV (Ad hoc On-

Demand Vector Routing).

• Route discovery: instead of keeping a route map, routes are discovered when they are needed.

• Selective ACKs: only the recipient responds to route messages.

• Reliability: the use of ACKs ensures data transmission reliability.

• Sleep modes: low energy consumption modes with synchronization to wake at the same time.

The classic topology of this type of network is mesh, as the nodes can establish point-to-point connections with brother nodes through the use the MAC address doing multi-hop connections when it is necessary.

Figure: Mesh topology

The XBee DigiMesh modules share the hardware module with the XBee-PRO 802.15.4. So it is possible to change the firmware of this kind of modules from one to another and vice versa (this can be done with a Gateway). For this reason, the characteristics related to the hardware are the same.

The XBee DigiMesh modules are based on the standard IEEE 802.15.4

that supports functionalities enabling mesh topology use.

LoRaWAN modules

10. LoRaWAN modules

LoRaWAN is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery-operated devices in regional, national or global network. LoRaWAN target key requirements of Internet of things such as secure bi-directional communication, mobility and localization services. This standard will provide seamless interoperability among smart Things without the need of complex local installations and gives back the freedom to the user, developer, businesses enabling the role out of Internet of Things.

LoRaWAN network architecture is typically laid out in a star-of-stars topology in which gateways is a transparent bridge relaying messages between end-devices and a central network server in the back-end. Gateways are connected to the network server via standard IP connections while end-devices use single-hop wireless communication to one or many gateways.

Figure: LoRaWAN network

Communication between end-devices and gateways is spread out on different frequency channels and data rates.

The selection of the data rate is a trade-off between communication range and message duration. Due to the spread spectrum technology, communications with different data rates do not interfere with each other and create a set of “virtual” channels increasing the capacity of the gateway. To maximize both battery life of the enddevices and overall network capacity, the LoRaWAN network server is managing the data rate and RF output for each end-device individually by means of an adaptive data rate (ADR) scheme.

National wide networks targeting Internet of Things such as critical infrastructure, confidential personal data or critical functions for the society has a special need for secure communication. This has been solved by several layer of encryption.

Note: The LoRa module is provided with a 4.5 dBi antenna, which enables maximum range.

This radio module provides an optimum range performance, thanks to the excellent receiver sensitivity that the

LoRa™ technology offers. Besides, Libelium developed a library which enables addressable, reliable and robust communications with ACK, re-tries or time-outs strategies.

The user can set any frequency in the 868 and 900 MHz bands, with pre-defined channels. The use of this module is allowed in virtually any country.

Encryption is implemented in the application level, thanks to the Waspmote’s AES library. The payload inside the wireless packet is encrypted so only nodes knowing the key can read the content. The encryption activation is as simple as running one of our LoRa with AES encryption examples.

The topology for this type of network is a star topology, as the nodes can establish point-to-point connections with brother nodes, normally with the central one.

NB-IoT / Cat-M module

19. NB-IoT / Cat-M module

Due to the popularity of Low Power Wide Area Networks (LPWAN) such as LoRaWAN or Sigfox in the IoT industry, the traditional cellular networks like 4G have been ousted as the best choice, specially when low cost, low power consumption and long range are key characteristics. As a response to this market demand, the 3GPP association published 2 cellular narrow band IoT standards in the release 13: NB-IoT (“narrow band for the Internet of Things”) and Cat-M (“category machine”). They are also known as LTE Cat-NB1 and LTE Cat-M1. Libelium has integrated the

BG96 chipset by Quectel to meet this requirement.

This module has been included in the Waspmote ecosystem as an OEM development kit, where the NB-IoT and the Cat-M connectivities can be easily tested in pilot projects or proof of concepts applications.

The NB-IoT / Cat-M module also includes EGPRS connectivity, allowing to transmit information even if there is no coverage for NB-IoT or Cat-M and also maintaining ultra-low power consumption. Besides, the most common

Internet protocols like HTTP(S), FTP(S), SSL, TCP or UDP are supported.

Moreover, the module integrates a GNSS engine supporting GPS, BeiDou, Galileo, GLONASS and QZSS systems, making it suitable for tracking applications where low cost and accurate positioning is needed.

Designed to be plugged on the socket1 of Waspmote, the module can meet almost all requirements for IoT applications like smart cities, remote monitoring, smart logistics, real-time tracking, etc. Additionally, the NB-IoT /

Cat-M module has a unique global version, allowing the usage all over the world with no fragmentation.

Like other radio modules, Libelium provides a dedicated library for Waspmote and some example codes, which speed up the testing for the NB-IoT or the Cat-M connectivity with just a few high-level functions, and without dealing with AT commands. Thus, the development of pilot projects and proof of concepts becomes easy.

Note: It is important to remark that the NB-IoT or Cat-M connectivities require a dedicated SIM card (not included by default). With a standard SIM card, only the EGPRS connectivity can be tested. Besides, the network coverage is only present in certain zones and strongly depends on the selected mobile network operator. It is recommended to check operators coverage in the location where the module will be used.

Over the Air Programming (OTA)

23. Over the Air Programming (OTA)

23.1. Overview

The concept of Wireless Programming or commonly known as Programming Over the Air (OTA) has been used in the past years overall for the reprogramming of mobile devices such as cell phones. However, with the new concepts of Wireless Sensor Networks and the Internet of Things where the networks consist of hundreds or thousands of nodes OTA is taken to a new direction.

Libelium provides an OTA method based on FTP transmissions to be used with GPRS, 3G, 4G and WiFi modules.

23.2. OTA with 4G/GPRS/WiFi modules via FTP

It is possible to update the Waspmote’s program using Over The Air Programming and the following modules:

4G/3G, GPRS or WiFi module.

The Waspmote reprogramming is done using an FTP server and an FTP client (which is Waspmote itself). The FTP server can be configured by Meshlium. Otherwise, the user will have to setup an FTP server.

Figure: OTA via FTP protocol

-116v8.2

Over the Air Programming (OTA)

There are 2 basic steps involved in OTA procedure:

• Step 1: Waspmote requests a special text file which gives information about the program to update: pro gram name, version, size, etc.

• Step 2: If the information given is correct, Waspmote queries the FTP server for a new program binary file and it updates its flash memory in order to run the new program.

Figure: OTA steps via FTP protocol

-117v8.2

Encryption libraries

24. Encryption libraries

The Encryption Libraries are designed to add to the Waspmote sensor platform the capabilities necessary to protect the information gathered by the sensors. To do so, 2 cryptography layers are defined:

• Link Layer: In the first one all the nodes of the network share a common preshared key which is used to en crypt the information using AES 128. This process is carried out by specific hardware integrated in the same

802.15.4/ZigBee radio, allowing the maximum efficiency of the sensor nodes energy consumption. This first security layer ensures no third party devices will be able to even connect to the network (access control).

• Secure Web Server Connection: The second security technique is carried out in Meshlium -the Gateway- where HTTPS and SSH connections are used to send the information to the Cloud server located on the

Internet.

A third optional encryption layer allows each node to encrypt the information using the Public key of the Cloud server. Thus, the information will be kept confidentially all the way from the sensor device to the web or data base server on the Internet.

Transmission of sensor data:

Information is encrypted in the application layer via software with AES 256 using the key shared exclusively between the origin and the destination. Then the packet is encrypted again in the link layer via hardware with AES

128 so that only trusted packets be forwarded, ensuring access control and improving the usage of resources of the network.

-118v8.2

GPS

25. GPS

Waspmote can integrate a GPS receiver which allows to know the exact location of the mote anytime. Thus, the exact position of the mote can be obtained and even the current time and date, to synchronize the Waspmote internal clock (RTC) with the real time. Besides, data can be geolocated on a map.

Figure: GPS module

The GPS module gives us information about:

• latitude

• longitude

• altitude

• speed

• direction

• date/time

• ephemeris

The functions implemented in the API allow this information to be extracted simply, calling functions such as:

{

GPS.getAltitude();

GPS.getSpeed();

GPS.getLongitude();

GPS.getLatitude();

}

The GPS receiver uses the UART_1 to communicate with the microcontroller, sharing this UART with the GPRS,

3G, , NB-IoT / Cat-M or 4G modules. As up to 2 modules share this UART, a multiplexer has been enabled in order to select the module with which we wish to communicate at any time. This is not a problem; since all actions are sequential , in practice there is parallel availability of both devices.

The GPS starts up by default at 4800 bps. This speed can be increased using the library functions that have been designed for controlling and managing the module.

The GPS receiver has 2 operational modes: NMEA (National Marine Electronic Association) mode and binary mode . NMEA mode uses statements from this standard to obtain location , time and date . The binary mode is based on the sending of structured frames to establish communication between the microcontroller and the GPS receiver, i.e. to read/set ephemeris.

-119v8.2

GPS

The different types of NMEA statements that the Waspmote’s built-in GPS receiver supports are:

• NMEA GGA: provides location data and an indicator of data accuracy

• NMEA GSA: provides the status of the satellites the GPS receiver has been connected to

• NMEA GSV: provides information about the satellites the GPS receiver has been connected to

• NMEA RMC: provides information about the date, time, location and speed

• NMEA VTG: provides information about the speed and course of the GPS receiver

• NMEA GLL: provides information about the location of the GPS receiver

The most important NMEA statements are the GGA statements which provide a validity indicator of the measurement carried out, the RMC statement which provides location, speed and date/time and the GSA statement which provides information about the status of the satellites the GPS receiver has been connected to.

(To obtain more information about the NMEA standard and the NMEA statements, visit the website: http://www.gpsinformation.org/dale/nmea.htm

)

Figure: GPS module connected to Waspmote

The GPS receiver needs time to obtain and structure the information that the satellites send. This time can be reduced if there is certain prior information. This information is stored in the almanacs and ephemeris. The information that can be found out is relative to the current position of the satellites (ephemeris) and the trajectory they are going to follow over the next days (almanacs). The almanacs indicate the trajectory that the satellites are going to follow during the next days, having a validity of some 2-3 months. The ephemeris indicate the current position of the satellites and have a validity of some 3-5 hours.

Depending on the information that the GPS receiver has, the start ups can be divided into these types:

• Hot start: once the time and date are established and the ephemeris and valid almanacs are in the memory. Time: <1 s.

• Cold start: without having established the time, date, almanacs or ephemeris. Time: <35 s.

As can be observed, the start up time reduces greatly, particularly when ephemeris are stored . For this reason a series of functions have been created in the libraries to store ephemeris on the SD card and enable them to be loaded later .

SD memory card

26. SD memory card

Waspmote has external storage support such as SD (Secure Digital) cards. These micro-SD cards are used specifically to reduce board space to the minimum.

Note: Until February 2018, 2 GB SD cards were distributed; they operated with FAT16. Since that moment, Libelium distributes FAT32 micro SD cards (8 GB cards from February; 16 GB cards from June). These cards need the bootloader

#J to work properly.

Micro-SD card

Waspmote uses the FAT32 file system. The information that Waspmote stores in files on the SD can be accessed from different operating systems such as Linux, Windows or Mac-OS.

Figure: SD card slot

To communicate with the SD module we use the SPI bus. This bus is a communication standard used to transfer information between electronic devices which accept clock regulated bit flow.

The SD card is powered through a digital pin from the microcontroller. It is not therefore necessary to use a switch to cut the power, putting a low pin value is enough to set the SD consumption to 0 μA .

For example, to get an idea of the capacity of information that can be stored in a 16 GB card, simply divide its size by the average for what a sensor frame in Waspmote usually occupies (approx. 100 bytes):

16 GB/100 B = 160 million measurements

The limit in files and directories creation per level is 256 files per directory and up to 256 sub-directories in each directory. There is no limit in the number of nested levels.

Related API libraries: WaspSD.h, WaspSD.cpp

All information about their programming and operation can be found in the SD Card Programming Guide .

All the documentation is located in the Development section in the Libelium website.

Note: Make sure Waspmote is switched off before inserting or removing the SD card. Otherwise, the SD card could be damaged.

28.1. Battery

Libelium offers 2 types of battery for the Waspmote OEM line:

• a 6600 mA·h, rechargeable lithium-ion battery (Li-Ion), with 3.7 V nominal voltage

• a 52000 mA·h, non-rechargeable battery, with 3.4 V nominal voltage

Waspmote has a control and safety circuit which makes sure the battery charge current is always adequate.

Figure: Battery connector

Battery connection

The figure below shows the connector in which the battery is to be connected. The position of the battery connector is unique, therefore it will always be connected correctly (unless the connector is forced).

Figure: Battery connection

-124v8.2

Power supplies

Battery discharging

Figure: Typical discharging curve for battery

Characteristics of the equipment used to generate charging curves:

Battery used: 3.7 V - 6600 mA·h battery

As seen above, the rechargeable battery shows a nice slope on its output voltage as its level goes down. Waspmote monitors this voltage in order to calculate the current battery level. However, a rechargeable battery has a very plain discharge graph, so it is not possible to know the remaining energy inside it.

Notes about the rechargeable battery:

• When recharging, if the battery is near 0%, it will take some time before the battery level increases.

• It is normal to see some battery level variations during the charging periods due to the Waspmote charging circuitry. To know the real battery level of the node, it is recommended to measure it when the node is not being recharged and also with sensors and radio modules switched off.

Warning: Batteries with voltage over 3.7 V could irreparably damage Waspmote.

Incorrect battery connection could irreparably damage Waspmote.

DO NOT TRY TO RECHARGE THE NON-RECHARGEABLE BATTERY, IT MAY EXPLODE AND CAUSE INJURIES

AND DESTROY THE EQUIPMENT. USE NON-RECHARGEABLE BATTERIES ONLY WITH DEVICES PROPERLY

PREPARED. PLEASE DOUBLE CHECK THIS CONDITION BEFORE CONNECTING THE USB OR THE SOLAR

PANEL.

Working environment

29. Working environment

The Integrated Development Environment (IDE) is used for writing the code and uploading it to Waspmote and

Plug & Sense!. It is also used to monitor serial output and for debugging. This IDE contains the Waspmote API (the

API is the set of all libraries Waspmote needs for compiling programs). New API versions are released instantly by

Libelium whenever improvements are made or bugs fixed.

Figure: Waspmote IDE

All information about the IDE installation and operation can be found in the IDE User Guide .

30.1. Receiving XBee frames with Waspmote Gateway

30.1.1. Waspmote Gateway

This device allows to collect data which flows through the sensor network into a PC or device with a standard USB port. Waspmote Gateway will act as a ”data bridge or access point” between the sensor network and the receiving equipment. This receiving equipment will be responsible for storing and using the data received depending on the specific needs of the application.

Figure: Waspmote Gateway

The receiving equipment can be a PC with Linux, Windows or Mac-OS, or any device compatible with standard

USB connectivity. The gateway offers a male USB A connector, so the receiving device has to have a female USB

A connector.

Once the Gateway is correctly installed, a new communication serial port connecting directly to the XBee module’s

UART appears in the receiving equipment, which allows the XBee to communicate directly with the device, being able to both receive data packets from the sensor network as well as modify and/or consult the XBee’s configuration parameters.

Another important function worth pointing out is the possibility of updating or changing the XBee module’s firmware .

Figure: Waspmote Gateway connected to a PC

-131v8.2

Interacting with Waspmote

LEDs

Four indicator LEDs are included in the Gateway:

• USB power LED: indicates that the board is powered through the USB port

• RX LED: indicates that the board is receiving data from the USB port

• TX LED: Indicates that the board is sending data to the USB port

• I/O 5 configurable LED: associate

The configurable LED connected to the XBee’s I/O 5 pin can be configured either as the XBee’s digital output or as the XBee’s indicator of association to the sensor network.

Buttons

• Reset: allows the XBee module to be reset

• I/O - 0: button connected to the XBee’s I/O pin 0

• I/O -1: button connected to the XBee’s I/O pin 1

• RTS - I/O – 6: button connected to the XBee’s I/O pin 6

All the buttons connect each one of its corresponding data lines with GND with when pressed. None of these have pull-up resistance so it may be necessary to activate any of the XBee’s internal pull-up resistances depending on the required use.

Figure: LEDs in Waspmote Gateway

30.1.2. Linux receiver

When using Linux it is possible to use various applications to capture the input from the serial port. Libelium recommends to use the ‘Cutecom’ application.

Once the application is launched, the speed and the USB where Waspmote has been connected must be configured.

The speed that must be selected is 115200 bps which is the standard speed set up for Waspmote.

The USB where Waspmote has been connected must be added the first time this application is run, adding USB0,

USB1, etc (up to the USB number of each computer) according to where Waspmote has been connected. For this, the ‘Device’ window must be modified so that if Waspmote is connected to USB0, this window contains ‘/dev/ ttyUSB0’.

Once these parameters are configured, capture is started by pressing the ‘Open Device’ button.

-132v8.2

Interacting with Waspmote

Figure: Cutecom application capturing Waspmote’s output

Linux Sniffer

As well as using the terminal to see the sensor information, an application which allows this captured data to be dumped to a file or passed to another program to be used or checked has been developed.

File:

“sniffer.c”

Compilation on Linux: gcc sniffer.c -o sniffer

Examples of use:

Seeing received data: ./sniffer USB0

Dumping of received data to a file: ./sniffer USB0 >> data.txt

Passing received values to another program: ./sniffer USB0 | program

Note: The speed used for the example is 19200 bps. The final speed will depend on the speed the XBee module has been configured with (default value 115200).
