Publishing for Bluetooth Asia 2018 developer session: mesh session. This repo is for GenericOnOff client side firmware.
EULA
PLEASE READ MESH_DEMO_TUTORIAL_EULA.TXT BEFORE START DEVELOPMENT.
Overview
This sample demonstrates Bluetooth Mesh functionality on micro:bit. It doesn't need provisioning because all the credential material (DevKey, NetKey, AppKey, Key Index, IVI and Unicast address) is pre-configured. This sample work as a GenericOnOff client:
- Pressing Button A on micro:bit will send GenericOnOffSet access message with on or off state alternatively and specific group address;
- Pressing Button B on micro:bit will switch the group address from 0xC000 to 0xC003 and back to 0xC000 again like round robin;
Requirements
micro:bit board
Building and Running
0. Download source code, it's zip file, the link is on this page, Download repository
.
1. Following below link to set the development environment up on your Windows computer. http://docs.zephyrproject.org/getting_started/installation_win.html . Please make sure git checkout this commit, commit: 88dfd399f480b1593a8e13f5a68d512921a55502 , the detail is here, https://github.com/zephyrproject-rtos/zephyr/commit/88dfd399f480b1593a8e13f5a68d512921a55502
2. copy zip file into ./zephyr/sample/
in the Zephyr tree.
3. unzip the file by "Extract Here".
3. access into the extracted folder and rename prj_bbc_microbit.txt
to prj_bbc_microbit.conf
4. if adopting Windows Command Prompt, use it to access into the unzip folder and type following commands on the console:
mkdir build & cd build
cmake -GNinja -DBOARD=bbc_microbit ..
ninja
if adopting MSYS2, use it to access into the unzip folder and type following commands on the console:
mkdir build & cd build
cmake -GNinja -DBOARD=bbc_microbit ..
ninja
5. connect micro:bit with your computer by USB cable, the board will be enumerated as a massive storage device;
6. drag the hex file (which is in ./zephyr/sample/[unzip folder]/build/zephyr/zephyr.hex
) into
Microbit massive storage device to flash the firmware;
7. micro:bit is ready to work as a GenericOnOff client.
