Dear forum members, Are there any examples available on how to do bluetooth communication between a micro:bit and X3 control board?
micro:bit does not support BLE scanning and connecting to other devices (Bluetooth Central mode). It can only receive connections (Bluetooth peripheral mode). For example - it can become visible to a smartphone, but it can’t search for other devices as smartphone does.
Although, this may be doable with micro:bit v2 (has new processor), but it came recently and it’s not that wide spread.
We have a tutorial how to control X3 from third-party products containing ESP32 processor: Use third-party boards - Totem Programming
