Installing CircuitPython on the microcontroller according the instruction.
-
Add CircuitPython library files. Can be download from the official libraries on the CircuitPython website. Required libriaries are:
- /adafruit_ble
- /adafruit_ble_adafruit
- /adafruit_bluefruit_connect
- /adafruit_bus_device
- /adafruit_hid
- /adafruit_lsm6ds

To have control with battery charging current download the latest version of seeed_xiao_nrf52840.py or take it from release and place directly on the CIRCUITPY drive.
Note: seeed_xiao_nrf52840.py is included in the release files but may be out of date. If you don't care about the latest versions, you can skip this step.
Copy the files onto the CIRCUITPY directly.
For the right controller change file name right_config.py to the config.py. File left_config.py can be deleted.
For the left controller change file name left_config.py to config.py. File right_config.py can be deleted.
Reconnect device. Will be visible for Bluetooth and ready to connect.
