STM32W-RFCKIT
Low-cost RF control kit for STM32W108xx microcontrollers
1 Introduction
The STM32W-RFCKIT low-cost RF control kit is an easy-to-use tool for STM32W108xx RF
microcontrollers. This family of microcontrollers integrates a 32-bit ARM® Cortex™-M3
microprocessor and a 2.4 GHz, IEEE 802.15.4-compliant transceiver. The kit demonstrates
plug and play 2.4GHz RF point-to-point communications targeting general-purpose wireless
control systems.
The STM32W-RFCKIT RF control kit provides demonstration applications and
documentation which serve as a reference for creating your own applications and re-
programming the STM32W108xx microcontroller.
You can run the STM32W-RFCKIT RF control kit in several ways using the dedicated
software libraries (Simplified MAC, ZigBee RF4CE and ZigBee PRO). This kit provides
access to a set of straightforward HAL APIs enabling application engineers to easily develop
RF control capabilities such as LEDs, serial communication channels (virtual COM through
USB), MEM enabled pointers, etc. Moreover, thanks to the flexibility of STM32W
microcontrollers, developers will also be able to use the kit with other available protocol
network libraries: MAC based, RF4CE, ZigBee PRO or 6LowPan.

The MB950 application board can be powered as follows:
●Via batteries
●Via USB
To power on the MB951 USB dongle, simply plug it into a PC USB port.
2.3.2 Installing the ST Virtual COM port driver USB drive
To use the serial communication channel on the kit application boards, a Virtual COM port
driver for STM32F103xx must be installed. This driver can be directly downloaded from the
ST website at http://www.st.com/internet/com/SOFTWARE_RESOURCES/
SW_COMPONENT/SW_DRIVER/vcpdriver_v1.zip
2.3.3 Setting up the application serial communication channel
To setup a serial communication channel for the kit application boards, follow these steps:
1. On the MB950 application board, connect a mini-USB cable between the board’s mini-
USB connector and a PC USB port.
2. Plug the MB951 USB dongle into a PC USB port.
3. Using the mouse, right-click on My Computer, select Manage, Device Manager, and
open Ports (COM & LPT) to display the related USB COMx ports.
4. Open a Hyper Terminal on the corresponding USB virtual COMx ports with the
following configuration:
Bit rate: 115200; Data bits: 8; Parity: None; Stop bits: 1; Flow control: None

3 Running the STM32W-RFCKIT RF control kit
In the STM32W-RFCKIT RF control kit, the Simple MAC talk application is preprogrammed
on both kit boards.
The Simple MAC talk demonstration application is a simple application that demonstrates
point-to-point IEEE 802.15.4 wireless communications using the STM32W108xx MCU.
It allows basic RF control of the USB dongle LEDs by pushing the application board's
buttons. Further, it can be used as a wireless RS-232 cable replacement. For example, all
data received on the serial port will be sent wirelessly to the other board and all the data
received wirelessly will be sent to the serial port.
3.1 Installing the STM32W-RFCKIT RF control kit software tree
To install the specific kit software and documentation tree, download the related installer file
from the STM32W 32-bit RF microcontroller webpages, then start the installation process
on your destination folder.
3.1.1 Building and download the Simple MAC talk demonstration application
The Simple MAC talk demonstration application runs on all STM32W-RFCKIT RF control kit
boards.
Using the prebuilt talk binary image
To download and run the prebuilt talk binary image on the kit's board, use the
stm32w_flasher utility with the prebuilt talk.s37 binary file. For information on how to use the
stm32w_flasher utility, refer to Section 4.1: stm32w_flasher utility.
Using the talk IAR project
An IAR workspace is also provided for building the Simple MAC talk demonstration
application.
Follow these steps to build the talk demonstration application image talk.s37.
1. Open the IAR toolset.
2. From the File, Open, Workspace menu, open the talk.eww IAR project.
3. From the Project menu, select Rebuild All. A binary file talk.s37 is built in the specific
demonstration application directory under the selected installation path.
Note: For the talk application, two workspaces are provided:
1. STM32W108 used to build a binary image with no IAP bootloader support.
2. STM32W108-btl used to build a binary image supporting the IAP bootloader (file
iap_bootloader.s37 in the prebuilt folder).

3.1.2 Basic RF communication using the talk demonstration application
Once the talk application has been loaded on the kit's board, different RF communication
scenarios can be targeted as described in the table below.
Note: 1 When pressing a button on the application board, LED D1 is turned on, indicating a packet
is going to be sent.
2 When pressing a button on the application board, if something is wrong with the current RF
communication (packet transmission failed or no acknowledgment received from the USB
dongle), the application board LEDs D1 and D3 start blinking for few seconds.
For setting a “chat communication”, it is requested to setup a serial communication channel
on both kit's boards by following the steps described in Section 2.3.3: Setting up the
application serial communication channel.
Once the serial communication channels of the kit's boards are correctly configured, the two
talk demonstration applications can communicate by typing the “chat text” on the
corresponding HyperTerminal.
The above example application shows how an RS-232 cable connection between two
devices can be replaced with a wireless system using STM32W108xx microcontrollers.

4.1 stm32w_flasher utility
The stm32w_flasher utility allows you to download a binary file into the STM32W-RFCKIT
RF control kit's boards. This utility comes with the Simple MAC software installer file.
To download a binary image, follow these steps:
1. Connect the kit board to a PC USB port.
2. Using the mouse, right-click on My Computer, select Manage, Device Manager, and
open Ports (COM & LPT) to display the related USB COMx port.
3. Open a DOS Window on your PC and go to the utilities folder which is created after the
installation process.
4. Type the following command:
stm32w_flasher -p <COMx> -r -f <file_name.bin/.s37>
where COMx is the virtual COM related to the connected application board, and
file_name.bin/.s37 is the application image to be downloaded.
