some-bluetooth-thing

Bluetooth messaging between Arduino Uno R4 and Raspberry Pi 5

Steps to remember for other devices

1. install the R4 core: arduino-cli core install arduino:renesas_uno
2. fqbn and device path: arduino-cli board list
3. easy compile step: arduino-cli compile --fqbn arduino:renesas_uno:unor4wifi some-bluetooth-thing.ino
4. upload arduino-cli upload -p /dev/ttyACM0 --fqbn arduino:renesas_uno:unor4wifi some-bluetooth-thing.ino
