Introduction
1. Introduction
The BGM111 Blue Gecko Bluetooth Module itself is featured on a Radio Board that forms a complete reference design, inluding the RF
section and other components.
The BGM111 Radio Board plugs directly into a Wireless Starter Kit Mainboard. The WSTK Mainboard features several tools for easy
evaluation and development of wireless applications. An on-board J-Link debugger enables programming and debugging on the target
device over USB or Ethernet. The Advanced Energy Monitor (AEM) offers real-time current and voltage monitoring. A virtual COM port
interface (VCOM) provides an easy-to-use serial port connection over USB or Ethernet. The Packet Trace Interface (PTI) offers invaluable debug information about transmitted and received packets in wireless links.
All debug functionality, including AEM, VCOM and PTI, can also be used towards external target hardware instead of the attached radio
board.
To further enhance its usability, the WSTK Mainboard contains sensors and peripherals demonstrating some of the BGM111's many
capabilities.
The Wireless Starter Kit for BGM111 includes an add-on board (BRD8006A) that can be connected to the WSTK Mainboard expansion
header. The expansion board contains additional peripherals such as an accelerometer, buttons, LEDs, joystick and a footprint for an
I2C authentication device.
1.1 Radio Boards
A Wireless Starter Kit consists of one or more mainboards and radio boards that plug into the mainboard. Different radio boards are
available. Each featuring different Silicon Labs devices with different operating frequency bands.
Since the mainboard is designed to work with all different radio boards, the actual pin mapping from a device pin to a mainboard feature
is done on the radio board. This means that each radio board has its own pin mapping to the Wireless Starter Kit features such as
buttons, LEDs, the display, the EXP header and the breakout pads. Because this pin mapping is different for every radio board, it is
important that the correct document be consulted which shows the kit features in context of the radio board plugged in.
This document explains how to use the Wireless Starter Kit (Wireless STK) when the BGM111 Bluetooth Module Radio Board
(BRD4300A) is combined with a Wireless STK Mainboard. The combination of these two boards is hereby referred to as a Wireless
Starter Kit (Wireless STK).

4.2 Expansion Header
On the right hand side of the board an angled 20-pin expansion header is provided to allow connection of peripherals or plugin boards.
The connector contains a number of I/O pins that can be used with most of the BGM111 Blue Gecko's features. Additionally, the VMCU,
3V3 and 5V power rails are also exported.
The connector follows a standard which ensures that commonly used peripherals such as an SPI, a UART and an I2C bus are available
on fixed locations in the connector. The rest of the pins are used for general purpose IO. This allows the definition of expansion boards
that can plug into a number of different Silicon Labs starter kits.
The figure below shows the pin assignment of the expansion header for the BGM111 Wireless Starter Kit. Because of limitations in the
number of available GPIO pins, some of the expansion header pins are shared with kit features.

4.3 Debug Connector
The Debug Connector serves multiple purposes based on the "debug mode" setting which can be configured in Simplicity Studio. When
the debug mode is set to "Debug IN", the debug connector can be used to connect an external debugger to the BGM111 on the radio
board. When set to "Debug OUT", this connector allows the kit to be used as a debugger towards an external target. When set to "Debug MCU" (default), the connector is isolated from both the on-board debugger and the radio board target device.
Because this connector is electronically switched between the different operating modes, it can only be used when the Board Controller
is powered (i.e. J-Link USB cable connected). If debug access to the target device is required when the Board Controller is unpowered,
connect directly to the appropriate breakout pins.
The pinout of the connector follows that of the standard ARM Cortex Debug+ETM 19-pin connector. The pinout is described in detail
below. Even though the connector has support for both JTAG and ETM Trace, it does not necessarily mean that the kit or the on-board
target device supports this.

• a 3 V coin cell battery; or
• a USB regulator on the Radio Board (for devices with USB support only).

Figure 5.1. Power Switch
With the switch in the AEM position, a low noise 3.3 V LDO on the WSTK Mainboard is used to power the Radio Board. This LDO is
again powered from the debug USB cable. The Advanced Energy Monitor is now also connected in series, allowing accurate high
speed current measurements and energy debugging/profiling.
With the switch in the USB position, radio boards with USB-support can be powered by a regulator on the radio board itself. BRD4300A
does not contain an USB regulator, and setting the switch in the USB postition will cause the BGM111 to be unpowered.
Finally, with the switch in the BAT position, a 20 mm coin cell battery in the CR2032 socket can be used to power the device. With the
switch in this position no current measurements are active. This is the recommended switch position when powering the radio board
with an external power source.
Note: The current sourcing capabilities of a coin cell battery might be too low to supply certain wireless applications.
Note: The Advanced Energy Monitor can only measure the current consumption of the BGM111 when the power selection switch is in
the AEM position.

Power Supply and Reset
5.2 Board Controller Power
The board controller is responsible for important features such as the debugger and the Advanced Energy Monitor, and is powered
exclusively through the USB port in the top left corner of the board. This part of the kit resides on a separate power domain, so a different power source can be selected for the target device while retaining debugging functionality. This power domain is also isolated to
prevent current leakage from the target power domain when power to the Board Controller is removed.
The board controller power domain is not influenced by the position of the power switch.
The kit has been carefully designed to keep the board controller and the target power domains isolated from each other as one of them
powers down. This ensures that the target BGM111 device will continue to operate in the USB and BAT modes.
5.3 BGM111 Reset
The BGM111 Bluetooth Module can be reset by a few different sources:
• A user pressing the RESET button.
• The on-board debugger pulling the #RESET pin low.
• An external debugger pulling the #RESET pin low.
In addition to the reset sources mentioned above, a reset to the BGM111 will also be issued during Board Controller boot-up. This
means that removing power to the Board Controller (plugging out the J-Link USB cable) will not generate a reset, but plugging the cable
back in will, as the Board Controller boots up.

The starter kit has a set of peripherals that showcase some of the features of the BGM111.
Be aware that most BGM111 I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when
using the breakout pads for your application.
6.1 Push Buttons and LEDs
The kit has two user push buttons marked PB0 and PB1. They are connected directly to the BGM111, and are debounced by RC filters
with a time constant of 1 ms. The buttons are connected to pins PF6 and PF7.
The kit also features two yellow LEDs marked LED0 and LED1, that are controlled by GPIO pins on the BGM111. The LEDs are connected to pins PF6 and PF7 in an active-high configuration.

6.2 Memory LCD-TFT Display
A 1.28-inch SHARP Memory LCD-TFT is available on the kit to enable interactive applications to be developed. The display has a high
resolution of 128 by 128 pixels, and consumes very little power. It is a reflective monochrome display, so each pixel can only be light or
dark, and no backlight is needed in normal daylight conditions. Data sent to the display is stored in the pixels on the glass, which means
no continous refreshing is required to maintain a static image.
The display interface consists of an SPI-compatible serial interface and some extra control signals. Pixels are not individually addressable, instead data is sent to the display one line (128 bits) at a time.
The Memory LCD-TFT display is shared with the kit Board Controller, allowing the Board Controller application to display useful information when the user application is not using the display. The user application always controls ownership of the display with the
DISP_ENABLE signal:
• DISP_ENABLE = LOW: The Board Controller has control of the display
• DISP_ENABLE = HIGH: The user application (BGM111) has control of the display
Power to the display is sourced from the target application power domain when the BGM111 controls the display, and from the Board
Controller's power domain when the DISP_ENABLE line is low. Data is clocked in on DISP_SI when DISP_CS is high, and the clock is
sent on DISP_SCLK. The maximum supported clock speed is 1.1 MHz.
DISP_COM is the "COM Inversion" line. It must be pulsed periodically to prevent static build-up in the display itself. Please refer to the
display application information for details on driving the display:

The Si7021 I2C relative humidity and temperature sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The patented use of industry-standard,
low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and
hysteresis, and excellent long term stability.
The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This
ensures that the sensors are fully interchangeable, with no recalibration or software changes required.
The Si7021 is available in a 3x3 mm DFN package and is reflow solderable. It can be used as a hardware- and software-compatible
drop-in upgrade for existing RH/ temperature sensors in 3x3 mm DFN-6 packages, featuring precision sensing over a wider range and
lower power consumption. The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during
assembly (e.g., reflow soldering) and throughout the life of the product, excluding liquids (hydrophobic/oleophobic) and particulates.
The Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature,
in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.
The I2C bus used for the Si7021 is shared with the Expansion Header. The temperature sensor is normally isolated from the I2C line. To
use the sensor, SENSOR_ENABLE (tied high) must be set high. When enabled, the sensor's current consumption is included in the
AEM measurements.

Expansion Board
8.2 Push Buttons and LEDs
The Expansion Board contains two push buttons (marked BTN2 and BTN3 on the PCB) and two LEDs (LED2 and LED3, not marked
but placed correspondingly above the push button markings). One push button and one LED share the same I/O pin on the BGM111.
The push button is connected to the LED through a transistor, allowing the I/O to be used either as an input (for reading the push button
state) or as an output (to control the LED state on or off).
When configured as an input, "0" indicates that the button is being pressed and "1" that the push button is not being pressed. Likewise,
when configured as an output, "0" will turn the LED on and "1" will turn it off.
Pressing a push button will also light up the corresponding LED because the LED is controlled by the same line (state) regardless of
whether it is the BGM111 or the push button that pulls the line low.
The each button is debounced by an RC filter with a time constant of about 1 ms. Pressing the push button while having the pin configured as an output in high state ("1") will not cause damage, but will cause extra current to flow.
8.3 Joystick
The analog joystick offers 9 measureable positions. This joystick is connected to the BGM111 pin PD4. Each of the joystick output pins
are connected to a different resistor value to create a unique voltage that is measured by the internal ADC on the BGM111. The joystick
output is connected to AD Channel 0 (ADC0). The figure below shows the connection between the joystíck and the BGM111.

Advanced Energy Monitor
9. Advanced Energy Monitor
9.1 Introduction
Any embedded developer seeking to make his embedded code spend as little energy as the underlying architecture supports, needs
tools to easily and quickly discover inefficiencies in the running application.
This is what the Simplicity Energy Profiler is designed to do. It will in real-time graph and log current as a function of time while correlating this to the actual target application code running on the BGM111. There are multiple features in the profiler software that allows for
easy analysis, such as markers and statistics on selected regions of the current graph or aggregate energy usage by different parts of
the application.
9.2 Theory of Operation
The Advanced Energy Monitor (AEM) circuitry on the board is capable of measuring current signals in the range of 0.1 µA to 95 mA,
which is a dynamic range of alomst 120 dB. It can do this while maintaining approximately 10 kHz of current signal bandwidth. This is
accomplished through a combination of a highly capable current sense amplifier, multiple gain stages and signal processing within the
kit's board controller before the current sense signal is read by a host computer for display and/or storage.
The current sense amplifier measures the voltage drop over a small series resistor, and the gain stage further amplifies this voltage with
two different gain settings to obtain two current ranges. The transition between these two ranges occurs around 250 µA.
The current signal is combined with the target processor's Program Counter (PC) sampling by utilizing a feature of the ARM CoreSight
debug architecture. The ITM (Instrumentation Trace Macrocell) block can be programmed to sample the MCU's PC at periodic intervals
(50 kHz) and output these over SWO pin ARM devices. When these two data streams are fused and correlated with the running application's memory map, an accurate statistical profile can be built, that shows the energy profile of the running application in real-time.
At kit power-up or on a power-cycle, and automatic AEM calibration is performed. This calibration compensates for any offset errors in
the current sense amplifiers.

9.3 AEM Accuracy and Performance
The AEM is capable of measuring currents in the range of 0.1 µA to 95 mA. For currents above 250 µA, the AEM is accurate within 0.1
mA. When measuring currents below 250 µA, the accuracy increases to 1 µA. Even though the absolute accuracy is 1 µA in the sub
250 µA range, the AEM is able to detect changes in the current consumption as small as 100 nA.
The AEM current sampling rate is 10 kHz.
Note: The AEM circuitry only works when the kit is powered and the power switch is in the AEM position.
9.4 Usage
The AEM data is collected by the board controller and can be displayed by the Energy Profiler, available through Simplicity Studio. By
using the Energy Profiler, current consumption and voltage can be measured and linked to the actual code running on the BGM111 in
realtime.

On-Board Debugger
10. On-Board Debugger
The Wireless Starter Kit contains an integrated debugger, which can be used to download code and debug the BGM111. In addition to
programming the BGM111 on the kit, the debugger can also be used to program and debug external Silicon Labs EFM32, EFM8,
EZR32 and EFR32 devices.
The debugger supports three different debug interfaces used with Silicon Labs devices:
• Serial Wire Debug, is used with all EFM32, EFR32 and EZR32 devices
• JTAG, which can be used with EFR32 and some EFM32 devices
• C2 Debug, which is used with EFM8 devices
In order for debugging to work properly, make sure you have the appropriate debug interface selected that works with your device. The
debug connector on the board supports all three of these modes.
10.1 Host Interfaces
The Wireless Starter Kit supports connecting to the on-board debugger using either Ethernet or USB.
Many tools support connecting to a debugger using either USB or Ethernet. When connected over USB, the kit is identified by its J-Link
serial number. When connected over Ethernet, the kit is normally identified by its IP address. Some tools also support using the serial
number when connecting over Ethernet, this typically require the computer and the kit to be on the same subnet for the discovery protocol (using UDP broadcast packets) to work.
USB Interface
The USB interface is available whenever the USB Mini-B connector on the left hand side of the mainboard is connected to a computer.
Ethernet Interface
The Ethernet interface is available when the mainboard Ethernet connector in the top left corner is connected to a network. Normally,
the kit will receive an IP address from a local DHCP server, and the IP address is printed on the LCD display. If your network does not
have a DHCP server, you need to connect to the kit via USB and set the IP address manually using Simplicity Studio, Simplicity
Commander or J-Link Configurator.
For the Ethernet connectivity to work, the kit must still be powered through the USB Mini-B connector. See 5.2 Board Controller Power
for details.
Serial Number Identification
All Silicon Labs kits have a unique J-Link serial number which identifies the kit to PC applications. This number is 9 digits, and is normally on the form 44xxxxxxx.
The J-Link serial number is normally printed at the bottom of the kit LCD display.

10.2 Debug Modes
Programming external devices is done by connecting to a target board through the provided Debug IN/OUT Connector, and by setting
the debug mode to [Out]. The same connector can also be used to connect an external debugger to the BGM111 Bluetooth Module on
the kit, by setting debug mode to [In].
Selecting the active debug mode is done with a drop-down menu in the Kit Manager tool in Simplicity Studio.

10.3 Debugging During Battery Operation
When the BGM111 is powered by battery and the J-Link USB is still connected, the on-board debug functionality is available. If the USB
power is disconnected, the Debug In mode will stop working.
If debug access is required when the target is running of another energy source, such as a battery, and the board controller is powered
down, the user should make direct connections to the GPIO used for debugging. This can be done by connecting to the appropriate
pins of the breakout pads. Some Silicon Labs kits provide a dedicated pin header for this purpose.

Device Connectivity
11. Device Connectivity
The Wireless STK Mainboard provides several convenient ways to communicate with a target application without soldering or using
external hardware.
11.1 Virtual COM Port
When the target device drives the VCOM_ENABLE (PA5) signal high, a communication line to the Board Controller is enabled. The
target can then communicate to the host computer via the Board Controller using USART0, Location 0 (TX pin PA0, RX pin PA1).
When enabling VCOM, the Board Controller makes communication to the host computer possible on the following interfaces:
• Virtual USB serial port using a CDC driver.
• TCP/IP, by connecting to the Wireless STK on port 4901 with a Telnet client.
Note: Only one of these can be used at the same time, meaning that if a socket is connected to port 4901, no data can be sent or
received on the USB COM port.
