1 Introduction

The hardware is the same for the cB-OLP425 Bluetooth Low Energy Platform and the Serial Port

Adapter cB-OLS425 except that the optional sensors and battery holder is not used and therefore not included in the cB-OLS425 Serial Port Adapter.

Figure 1: cB-OLP425x-26 Bluetooth Low Energy Platform with external antenna.

Figure 2: cB-OLS425x-04 Bluetooth Low Energy Serial Port Adapter with external antenna.

The cB-OLS426 is a cB-OLS425 module mounted on a carrier board which is physical compatible with the u-blox/connectBlue Classic Bluetooth Serial Port Adapters e.g. cB-OBS411

[3] and cB-OBS421 [4]

.

Figure 3 and figure 4 illustrates the physical compatibility.

Figure 4: cB-OBS411i-04 Bluetooth Serial Port Adapter with internal antenna.

The u-blox cB-OLP425 is a Bluetooth low energy platform module with a unique set of features and functionality that provides customers with a complete turnkey solution. The cB-OLP425 can either be delivered with digital and analog GPIOs or complete with battery holder, temperature sensor, 3-axis motion sensor/accelerometer, see

cB-OLP425 Platform variants . There are also 4x1 through holes to

solder wires or through hole components. Using the IAR Embedded Workbench, the customer embeds their own software and application in the cB-OLP425 module. Such possible software includes

Bluetooth low energy profiles/services/attributes and customer application such as machine/device access and asset management, data conversion, data acquisition, logic etc.

The low energy consumption is achieved by the Bluetooth Low Energy protocol with very rapid and short radio activity and long sleep times in between. During the radio activity and data processing phases the unit is consuming almost the same amount of energy as a Classic Bluetooth application and e.g. a Bluetooth low energy device used for continuous data transfer would not have a lower power


Page of 52

OLS425 / OLP425 series - Electrical Mechanical Data Sheet consumption than a comparable Bluetooth device transmitting the same amount of data. It would likely use more power, since the protocol is optimized for small bursts. It is important to understand the current consumption. It is important to understand the concept if low energy is important and we recommend the developer/user to read the

Calculating Energy Consumption

section.

The Bluetooth Low Energy Serial Port Adapters are similar to the u-blox/connectBlue Bluetooth Classic

Serial Port Adapters but with the Bluetooth Low Energy technology (much lower standby power consumption and faster response times but lower throughput). The cB-OLS426 module can in many cases replace the Bluetooth Classic modules in existing applications without redesigns if the Bluetooth

Low Energy features would gain the performance of the system. The cB-OLS425/426 is not equipped with any sensors or LEDs.

The hardware of the cB-OLP425/cB-OLS425 products is referred as cB-0950 and the module is Type

Approved with the type name cB-0950. The electrical differences between the cB-OLS426 and cB-

OLS426 is only the LDO regulator mounted on the carrier board and can also refer to the cB-0950 Type

Approval.

The modules are available in different configuration (see Product Variants

) with

Internal antennas

or a U.FL. connector for connecting an

External antenna

OLS425/426) does not include all functions as the platform (cB-OLP425). The cB-OLS426 is a cB-OLS425 mounted on a carrier board with an LDO regulator.

2.4 cB-OLP425 Bluetooth Stack and Application Platform Software


Page 11 of 52


The platform module cB-OLP425 is a hardware platform based on the Texas Instruments CC2540

[7]

system-on-chip (256 kB flash memory and 8 kB SRAM).

The TI chip runs both application and the Bluetooth low energy protocol stack. The

TI Bluetooth low energy software stack and tools

includes object code with the latest BLE protocol stack supporting multiple connections, sample projects and applications covering an extensive set of profiles with source code. Please note that this package is not provided by u-blox.

The cB-OLP425 sample code package includes sample projects for accessing the LEDs, temperature sensor and accelerometers.

All embedded software is developed using

IAR Embedded Workbench for 8051

.

NOTE

Software/firmware support is not included by u-blox. To sign a support agreement for software support or to discuss a full implementation project please contact us.

3 Electrical Interface and Connectors

3.1 Electrical Interface and Connectors on the cB-OLP425 Platform

3.1.1 cB-OLP425 Connector Interfaces

This section describes the signals available on the cB-OLP425 platform. There are three ways to connect to the cB-OLP425 platform:

Via the PCB solder pads on the edge of the PCB, J6 (see Figure 6). See Section " Using the J6 PCB solder pads " for more information.


Page 12 of 52


Via the JST connector, J8 (see Figure 7).

The JST connector is a 6 poles wire connector. The pitch is 1mm. The manufacturer of the mounted connector is JST and the part number is SM06B-SRSS-TB. The SM06B-SRSS-TB connector is mated with the wire connector SHR-06V-S from JST. Other connector options are also available from JST.

JST Connector

The JST connector does NOT contains a UART interface in contrast with many other ublox/connectBlue Serial Port Adapters OEM modules. The JST connector is a debug, firmware upgrade and IO interface on the cB-OLP425 modules. See the u-blox CC

Debugger Adapter Board - User Guide [8] and cB-OLP425 Development Kit Getting

started

[5] documentation for more info about the debug interface and how to use it.

Notice that the TI CC Debugger Adapter Cable (cB-ACC-71) included in the

Development kit can NOT directly be connected to the cB-OLP425 if the module at the same time has voltage supplied from another source e.g. a battery. A voltage supply collision will occur which could damage the electronics/battery because the CC

Debugger also includes a voltage supply pin which is connected to the voltage supply pin on the J8 JST connector via the adapter cable. It is strongly recommended to use the CC Debugger Adapter Board instead of the cB-ACC-71 cable.

Via the 4x1 through holes row J7 (see Figure 7) for solder wires or through holes components to the board (1.27mm pitch).

Figure 6: The solder pads J6 are available on the long edges of the bottom side of the PCB.

4.3 Current Consumption for cB-OLP425

The current consumption is very dependent of the customer implementation and because of this is specific current consumption data for cB-OLP425 not included in this documentation. The cB-OLP425 with a cB-OLS425 firmware would have the same current consumption as a cB-OLS425. Current consumption can be measure by measuring the voltage drop over an 10ohm resistor (I = V drop

/10ohm). The current peaks/activities is best visualized with an oscilloscope. Very low currents (uA) like the sleep currents can usually not be measured with an ordinary oscilloscope. Very low stable currents can instead be measure with an accurate multimeter. See

Calculating Energy Consumption and

[10]

for more info about current measurements.

4.4 Current Consumption for cB-OLS425 and cB-OLS426

Current consumption for cB-OLS425 and cB-OLS426. The cB-OLS426 has higher consumption because the internal LDO regulator. See

Calculating Energy Consumption and

[10]

for more info about current measurements.

The modules has an 100uF capacitance which makes the peaks lower compared to the actual radio current consumption peaks. The average measurements are also lower but the durations are longer and the energy consumption is preserved compared to the actual radio energy consumption.

4.7 Hardware Reset

A hardware input is available on the connectors (see external reset source must be open drain collector. The

Electrical Interface and Connectors ). An

pin is internally pulled-up with 50kohm.

5 Calculating Energy Consumption

The OLP425, cB-OLS425/426 is always a peripheral device and the energy consumption is usually a very important factor and it is important to understand how the Bluetooth Low Energy protocol works to optimize each specific application for low current consumption.


Page 25 of 52


Typical Bluetooth Low Energy application is sensors supplied with power from a 3.0V lithium coin cell battery like a CR2032. The coin cell battery has a relative high internal resistance (10-100ohm) and is not capable of delivering high currents. A 100uF capacitor is mounted to offload the power source.

During high current periods the capacitor will act as the primary power source, while during low current periods the battery will be the primary power source and recharge the capacitor, see Figure

10. The slope of the curves is dependent on the internal resistance of the battery and most measurements has 10ohm power source resistance.

Current consumption can be measure by measuring the voltage drop over a 10ohm resistor (I = V drop

/10ohm). The current peaks/activities are best visualized with an oscilloscope. Very low currents (uA) like the sleep currents can usually not be measured with an ordinary oscilloscope. Very low stable currents can instead be measure with an accurate multimeter. See

[10] for more info about current

measurements.

Figure 10: cB-OLS425 current consumption during advertising. The grey curve is moment radio consumption and the blue is smoothed-out because of the 100uF capacitance to offload the battery.

An 10ohm resistance is used as internal power source resistance in the measurements. The energy consumption (mAh) is the integration (area under the curves) of the curves.

7 Antennas

This chapter gives an overview of the different antenna options. All antennas options are the same for cB-OLP425, cB-OLS425 and cB-OLS426.

There are 2 different antenna options available:

Internal surface mounted (SMD) antenna.

An U.FL. connector for external antennas. Different types of external antennas are available.

The sections below lists the antennas that are included in the radio type approvals of the module. For each antenna the "Approvals" field defines in which test reports the antenna is included. Definitions of the "Approvals" field are:

FCC - The antenna is included in the FCC test reports, and thus approved for use in countries that accept the FCC radio approvals, primarily US.

IC - The antenna is included in the IC (Industrie Canada) test reports, and thus approved for use in countries that accept the IC radio approvals, primarily Canada.

R&TTE - The antenna is included in the R&TTE test reports, and thus approved for use in countries that accept the R&TTE radio approvals, primarily the European countries.

TELEC - The antenna is included in the Japanese government affiliated TELEC test reports, and thus approved for use in the Japanese market.

In general, antennas with SMD antenna, Reverse Polarity SMA connector or U.FL connector are included in FCC, IC, R&TTE and TELEC radio tests. Antennas with SMA connector are in general included in R&TTE and TELEC radio tests but not FCC or IC due to FCC/IC regulations.

Weight: 2 g

8.1.3 Using the J6 PCB Solder Pads

Host Board

The host PCB footprint should not contain any traces or vias under the module except the pads interfacing the J6 pads to avoid contact with traces/vias on the module. The host pads which are soldered to the J6 pads should have the same size as the module and can be extended some mm outside the module for manual soldering or inspection purpose. No other pads than the J6 should be soldered to the host PCB.

cB-OLP425 and cB-OLS425 Mounting Process

We strongly recommend the cB-OLP425 and cB-OLS425 modules not being soldered more than one time after shipping from u-blox and that the modules are mounted just before the host product is being soldered the last time. Although, u-blox devices will withstand up to two reflows to an absolute maximum temperature of 250°C.

The PCB in our modules is made of FR4-type with Chemical Gold Pads.

The modules are produced in a lead-free process with a lead-free soldering paste.

It is recommended that the customers make their own electrical, climate, stress and vibration tests on the final assembled product to secure that the manufacturing process hasn't damaged or affected the Bluetooth module in any way.


Page 38 of 52


The modules are normally delivered without labels on each module when packaged on tapeand-reel or tray since the labels do not withstand soldering. However, if they are delivered with labels on each module, the labels should be removed before the module is processed since the labels do not withstand the heat of soldering.

The device recommended maximum re-flow temperature is 245°C for 10 sec.

The device absolute maximum re-flow temperature is 250°C for 3 sec.

8.2 cB-OLS426 Mechanics

8.2.1 Module Dimensions

Figure 13: cB-OLS426 dimensions.

Weight: 3 g

8.2.2 cB-OLS426 Mounting Holes

There are 2 x 2.3mm mounting holes on the cB-OLS426 module. The reasons for the 2.3mm holes are that the threaded M2 holes on the single and double row connectors are not aligned. The outer tangents of the 2.3mm holes align the module if the single row connectors are used and the inner if double row connectors are used (see Figure 14).


Page 39 of 52


Figure 14: The 2.3mm mounting holes [mm].

8.2.3 Using the J2/J3 Board-to-Board Connectors

The board-to-board connector should be a 1mm pitch one-piece part connector. The recommended manufacture is Samtec .

The Electrical Interface and Connectors

section contains more information about the connector and the electrical interface.

Single Row Connectors

The single row connector SEI-120-02 can be used but is not recommended for new designs.

Double Row Connectors

This connector has a height of 3.0mm and this has to be considered if components are to be mounted on the motherboard under the OEM Serial Port Adapter board. There are alignment pins on the bottom side of the connector.

The connector is available with M2 threaded inserts that fit the mounting holes on the board (see section Mounting Holes ). If you want to have a tighter and more secure mounting you may use longer screws and secure it using a nut on the backside of the motherboard.

The host PCB footprint should not contain any traces or vias under the module except the pads interfacing the J6 pads to avoid contact with traces/vias on the module. The host pads which are soldered to the J6 pads should have the same size as the module and can be extended some mm outside the module for manual soldering or inspection purpose. No other pads than the J6 should be soldered to the host PCB.

cB-OLS426 Mounting Process

The cB-OLS426 is only guaranteed to withstand one reflow time after shipping from u-blox and it is recommended that the modules are mounted just before the host product is being soldered the last time.

The PCB in our modules is made of FR4-type with Chemical Gold Pads.

The modules are produced in a lead-free process with a lead-free soldering paste.

It is recommended that the customers make their own electrical, climate, stress and vibration tests on the final assembled product to secure that the manufacturing process hasn't damaged or affected the Bluetooth module in any way.

The device absolute maximum re-flow temperature is 250°C for 3 sec.

8.3 Antenna Issues

The unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna cannot be mounted in a metal enclosure. No metal casing or plastics using metal flakes should be used, avoid also metallic based paint or lacquer. Keep a minimum clearance of

5 mm between the antenna and the casing. Keep minimum 10 mm free space from metal around the antenna including under and above. If a metal enclosure is required, one of the external antenna options has to be used. See

Surface Mounted Antenna (Internal)

for more information on the antenna options available.
