UG338: BGM13P22 Blue Gecko Module Radio Board User's Guide
Introduction
1. Introduction
The BGM13P22 Blue Gecko Module is featured on a radio board that plugs directly into a Wireless Starter Kit (WSTK) Mainboard. The
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 mainboard contains sensors and peripherals that demonstrates some of the many capabilities of the
BGM13P22. A 20 pin expansion header (EXP header) is also provided that allows connection of expansion boards (EXP boards) to the
kit.
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 when the BGM13P22 Blue Gecko Module Radio Board (BRD4306A) is
combined with a Wireless STK Mainboard. The combination of these two boards is hereby referred to as a Wireless Starter Kit (Wire-
less STK).
1.2 Ordering Information
BRD4306A can be obtained as a separate radio board, SLWRB4306A. The radio board is intended to be used together with a Wireless
STK Mainboard that can be obtained with any Silicon Labs Wireless Starter Kit.

3.1 J-Link USB Connector
The J-Link USB connector is situated on the left side of the Wireless Starter Kit Mainboard. Most of the kit's development features are
supported through this USB interface when connected to a host computer, including:
• Debugging and programming of the target device using the on-board J-Link debugger
• Communication with the target device over the virtual COM port using USB-CDC
• Accurate current profiling using the AEM
In addition to providing access to development features of the kit, this USB connector is also the main power source for the kit. USB 5V
from this connector powers the board controller and the AEM. It is recommended that the USB host be able to supply at least 500 mA
to this connector, although the actual current required will vary depending on the application.
3.2 Ethernet Connector
The Ethernet connector provides access to all of the Wireless Starter Kit's development features over TCP/IP. The Ethernet interface
provides some additional development features to the user. Supported features include:
• Debugging and programming of the target device using the on-board J-Link debugger
• Communication with the target device over the virtual COM port using TCP/IP socket 4901
• "VUART" communication with the target device over the debug SWD/SWO interface using TCP/IP socket 4900
• Accurate current profiling using the AEM
• Real-time radio packet and network analysis using the Packet Trace Interface
• Access to advanced configuration options using the admin console over TCP/IP socket 4902
Please note that the Wireless Starter Kit cannot be powered using the Ethernet connector, so in order to use this interface, the USB
connector must be used to provide power to the board.

3.4 EXP Header
The EXP header is an angled 20-pin expansion header provided to allow connection of peripherals or plugin boards to the kit. It is loca-
ted on the right-hand side of the mainboard and it contains a number of I/O pins that can be used with most of the BGM13P 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 availa-
ble on fixed locations in the connector. The rest of the pins are used for general purpose IO. This allows the definition of expansion
boards (EXP boards) that can plug into a number of different Silicon Labs Starter Kits.
The figure below shows the pin assignment of the EXP header. Because of limitations in the number of available GPIO pins, some of
the EXP header pins are shared with kit features.

3.5 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 BGM13P 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 "De-
bug 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.

Note: The pinout matches the pinout of an ARM Cortex Debug+ETM connector, but these are not fully compatible as pin 7 is physically
removed from the Cortex Debug+ETM connector. Some cables have a small plug that prevent them from being used when this pin is
present. If this is the case, remove the plug, or use a standard 2x10 1.27 mm straight cable instead.

BRD8010A STK/WSTK Debug Adapter is an adapter board which plugs directly into the debug connector and the Simplicity Connector
on the mainboard. It combines selected functionality from the two connectors to a smaller footprint 10-pin connector, which is more
suitable for space constrained designs.
For versatility, the debug adapter features three different 10-pin debug connectors:
• Silicon Labs Mini Simplicity Connector
• ARM Cortex 10-pin Debug Connector
• Silicon Labs ISA3 Packet Trace
The ARM Cortex 10-pin Debug Connector follows the standard Cortex pinout defined by ARM and allows the Starter Kit to be used to
debug hardware designs that use this connector.
The ISA3 connector follows the same pinout as the Packet Trace connector found on the Silicon Labs Ember Debug Adapter (ISA3).
This allows the Starter Kit to be used to debug hardware designs that use this connector.
The Mini Simplicity Connector is designed to offer advanced debug features from the Starter Kit on a 10-pin connector:
• Serial Wire Debug (SWD) with SWO
• Packet Trace Interface (PTI)
• Virtual COM port (VCOM)
• AEM Monitored voltage rail
Note: Packet Trace is only available on Wireless STK Mainboards. MCU Starter Kits do not support Packet Trace.

4.1 Radio Board Power Selection
The BGM13P on a Wireless Starter Kit can be powered by one of these sources:
• The debug USB cable
• A 3 V coin cell battery
• A USB regulator on the radio board (for devices with USB support only)
The power source for the radio board is selected with the slide switch in the lower left corner of the Wireless STK Mainboard. The figure
below shows how the different power sources can be selected with the slide switch.

Figure 4.1. Power Switch
With the switch in the AEM position, a low noise 3.3 V LDO on the mainboard is used to power the radio board. This LDO is again
powered from the debug USB cable. The AEM 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. BRD4306A
does not contain an USB regulator, and setting the switch in the USB postition will cause the BGM13P 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 AEM can only measure the current consumption of the BGM13P when the power selection switch is in the AEM position.

4.2 Board Controller Power
The board controller is responsible for important features such as the debugger and the AEM, 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 BGM13P device will continue to operate in the USB and BAT modes.
4.3 BGM13P Reset
The BGM13P 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 BGM13P will also be issued during board controller boot-up. This
means that removing power to the board controller (unplugging the J-Link USB cable) will not generate a reset, but plugging the cable
back in will, as the board controller boots up.

5. Peripherals
The starter kit has a set of peripherals that showcase some of the features of the BGM13P.
Be aware that most BGM13P 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.
5.1 Push Buttons and LEDs
The kit features two user push buttons, marked PB0 (BUTTON0) and PB1 (BUTTON1), and two yellow LEDs, marked LED0 and LED1.
BUTTON0 and LED0 share the connection to GPIO pin PF6, and BUTTON1 and LED1 are both connected to PF7.
To use the push buttons as inputs to the BGM13P, each button's GPIO pin must be configured as an input. Configure the pins as out-
puts to control the LEDs. Note that LEDs are connected to GPIO pins in an active-low configuration.
The push buttons are debounced by RC filters with a time constant of 1 ms.

5.2 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 addressa-
ble, instead data is sent to the display one line (128 bits) at a time.
The Memory LCD-TFT display is shared with the kit's board controller, allowing the board controller application to display useful infor-
mation 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 (BGM13P) has control of the display
Power to the display is sourced from the target application power domain when the BGM13P 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_EXTCOMIN is the "COM Inversion" line. It must be pulsed periodically to prevent static build-up in the display itself. Refer to the
display application information for details on driving the display:

The MX25R series are ultra low power serial flash devices, so there is no need for a separate enable switch to keep current consump-
tion down. However, it is important that the flash is always put in deep power down mode when not used. This is done by issuing a
command over the SPI interface. In deep power down, the MX25R typically adds approximately 100 nA to the radio board current con-
sumption.

5.4 Si7021 Relative Humidity and Temperature Sensor
The Si7021 I2C relative humidity and temperature sensor is a monolithic CMOS IC integrating humidity and temperature sensor ele-
ments, 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 EXP header. The temperature sensor is normally isolated from the I2C line. To use
the sensor, SENSOR_ENABLE (PD15) must be set high. When enabled, the sensor's current consumption is included in the AEM
measurements.

Peripherals
5.5.1 Host Interfaces
Data sent to the board controller through the VCOM interface is available in two different ways to the user. At the same time, data can
be sent to the target device using these interfaces:
• Virtual COM port using a standard USB-CDC driver.
• TCP/IP, by connecting to the Wireless STK on TCP/IP port 4901 with a Telnet client.
When connecting via USB, the device should automatically show up as a COM port. Some examples of device names that can be as-
sosiated with the kit:
• JLink CDC UART Port (COM5) on Windows hosts
• /dev/cu.usbmodem1411 on macOS
• /dev/ttyACM0 on Linux
Note that these are only examples of what the device might show up as, and the actual assignment depends on the operating system,
and how many devices are or have been connected previously. Data sent by the target device into the VCOM interface can be read
from this port, and data written to this port is transmitted to the traget device.
Connecting to the Wireless STK on port 4901 gives access to the same data over TCP/IP. Data written into the VCOM interface by the
target device can be read from the socket, and data written into the socket is transmitted to the target device.
Note: Only one of these interfaces can be used at the same time, with the TCP/IP socket taking priority. This means that if a socket is
connected to port 4901, no data can be sent or received on the USB COM port.
5.5.2 Serial Configuration
By default, the VCOM serial port is configured to use 115200 8N1, with flow control disabled/ignored. (115.2 Kbit/s, 8 databits, 1 stop
bit). The configuration can be changed using the Admin Console:
WSTK> serial vcom config
Usage: serial vcom config [--nostore] [handshake <rts/cts/rtscts/disable/auto>] [speed <9600,921600>]
Using this command, the baud rate can be configured between 9600 and 921600 bit/s, and hardware handshake can be enabled or
disabled on either or both flow control pins.

5.5.3 Hardware Handshake
The VCOM peripheral supports basic RTS/CTS flow control.
VCOM_CTS (target clear to send) is a signal that is output from the board controller and input to the target device. The board controller
de-asserts this pin whenever its input buffer is full and it is unable to accept more data from the target device. If hardware handshake is
enabled in the target firmware, its UART peripheral will halt when data is not being consumed by the host. This implements end-to-end
flow control for data moving from the target device to the host.
VCOM_CTS is connected to the RTS pin on the board controller, and is enabled by setting handshake to either RTS or RTSCTS using
the "serial vcom config" command.
VCOM_RTS (target request to send) is a signal that is output form the target device and input to the board controller. The board control-
ler will halt transmission of data towards the target if the target device de-asserts this signal. This gives the target firmware a means to
hold off incoming data until it can be processed. Please note that de-asserting RTS will not abort the byte currently being transmitted,
so the target firmware must be able to accept at least one more character after RTS is de-asserted.
VCOM_RTS is connected to the CTS pin of the board controller, and is enabled by setting handshake to either CTS or RTSCTS using
the "serial vcom config" command in the Admin Console. If CTS flow control is disabled, the state of VCOM_RTS will be ignored and
data will be transmitted to the target device anyway.

the host to the target device.

Board Controller
6. Board Controller
The Wireless STK Mainboard contains a dedicated microcontroller for some of the advanced kit features provided. This microcontroller
is referred to as the board controller, and is not programmable by the user. The board controller acts as an interface between the host
PC and the target device on the radio board, as well as handling some house-keeping functions on the board.
Some of the kit features actively managed by the board controller are:
• The on-board debugger, which can flash and debug both on-board and external targets.
• The Advanced Energy Monitor, which provides real-time energy profiling of the user application.
• The Packet Trace Interface, which is used in conjunction with PC software to provide detailed insight into an active radio network.
• The Virtual COM Port and Virtual UART interfaces, which provide ways to transfer application data between the host PC and the
target processor.
• The admin console, which provides configuration of the various board features.
Silicon Labs publishes updates to the board controller firmware in the form of firmware upgrade packages. These updates may enable
new features or fix issues. See 9.1 Firmware Upgrades for details on firmware upgrade.
6.1 Admin Console
The admin console is a command line interface to the board controller on the kit. It provides functionality for configuring the kit behavior
and retreiving configuration and operational parameters.
6.1.1 Connecting
The Wireless Starter Kit must be connected to Ethernet using the Ethernet connector in the top left corner of the mainboard for the
admin console to be available. See 8.1.2 Ethernet Interface for details on the Ethernet connectivity.
Connect to the admin console by opening a telnet connection to the kit's IP address, port number 4902.
When successfully connected, a WSTK>prompt is displayed.

Advanced Energy Monitor
7. Advanced Energy Monitor
7.1 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. In real-time, the Energy Profiler will graph and log current as a function of
time while correlating this to the actual target application code running on the BGM13P. There are multiple features in the profiler soft-
ware 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.
7.2 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 Instrumentation Trace Macrocell (ITM) 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 appli-
cation'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, an automatic AEM calibration is performed. This calibration compensates for any offset errors in
the current sense amplifiers.

Advanced Energy Monitor
7.3 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.
7.4 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 BGM13P in
realtime.

On-Board Debugger
8. On-Board Debugger
The Wireless STK Mainboard contains an integrated debugger, which can be used to download code and debug the BGM13P. In addi-
tion to programming a target on a plug-in radio board, the debugger can also be used to program and debug external Silicon Labs
EFM32, EFM8, EZR32, and EFR32 devices connected through the debug connector.
The debugger supports three different debug interfaces for Silicon Labs devices:
• Serial Wire Debug is supported by all EFM32, EFR32, and EZR32 devices
• JTAG is supported by EFR32 and some EFM32 devices
• C2 Debug is supported by EFM8 devices
In order for debugging to work properly, make sure that the selected debug interface is supported by the target device. The debug con-
nector on the board supports all three of these modes.
8.1 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, however this typically requires the computer and the kit to be on the same subnet for the dis-
covery protocol (using UDP broadcast packets) to work.
8.1.1 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.
8.1.2 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 4.2 Board Controller Power
for details.
8.1.3 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 nor-
mally on the form 44xxxxxxx.
The J-Link serial number is normally printed at the bottom of the kit LCD display.

On-Board Debugger
Note: For "Debug IN" to work, the kit board controller must be powered through the Debug USB connector.
8.3 Debugging During Battery Operation
When the BGM13P 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 off 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.
