RAK4631 BLE UART example in Arduino IDE

Please include the following information, in order for us to help you as effectively as possible.

My question in why do I have to select “Adafruit Feather nRF52840 Express” in the Arduino IDE board manager for this sketch instead of “RAK wireless nRF boards\Wisblock RAK4631”? I’m relatively new at this and I spent a couple of days trying to figure out why the compiler couldn’t find the <bluefruit.h> library.

Which version of ArduinoIDE do you use?

It compiles fine with

  • Arduino IDE V1.8.19
  • Visual Studio Code with Arduino Extension

It throws an error with

  • Arduino IDE V2.2.3

No idea why.

Thank you for the reply. I’m using Arduino IDE Version 2.3.4
