Bluetooth: Peripheral HIDs Example¶
The Peripheral HIDs Example demonstrates how to use the Bluetooth Low Energy HID GATT Service. The report map used is for a generic mouse.
Before you start building, the Zephyr development environment should be set up correctly:
Build the example¶
You can find the source code and the project file of the example in the following folder: examples/zephyr/bluetooth/peripheral_hids.
Build the example by performing the following steps:
Open terminal and navigate to the
m2devkitdirectory created in the Setup the toolchain section:
westto build the example:
west build -b nrf52840_m2 nrf52840-m2-devkit/examples/zephyr/bluetooth/peripheral_hids
If a build system is present, make the build folder pristine before building:
west build -t pristine
Flash the example¶
After compiled successfully, the firmware is located in
m2devkit/build/zephyr with the name
Connect the debugger USB port to your PC using the provided USB-C Cable. A disk drive called M2-DOCK will be automatically detected by the computer.
Run the following command to flash the board:
Test the Peripheral HIDs Example application by performing the following steps:
Connect the debugger USB port to your PC
screen /dev/cu.usbmodem14102 115200
Press RESET button, and observe the output of the terminal:

Use a computer with Bluetooth Low Energy supported to connect the device. Here goes with macOS: Go to System Preferences -> Bluetooth Preferences, observe that the BLE HID Mouse named Test HoG mouse is found and click Connect.
You will be asked for a passkey. Enter the passkey printed in the terminal, then click Connect:
