BLE library for Beetle Bluno BLE with AVR architecture (ATmega328)

Question

When I try to #include <ArduinoBLE.h> in my Arduino program, I get the error:

WARNING: library ArduinoBLE claims to run on samd, megaavr, mbed, apollo3, mbed_nano, mbed_portenta architecture(s) and may be incompatible with your current board which runs on avr architecture(s).

Apart from potentially trying to import an incompatible library, am I doing something wrong? If not, are there any Arduino libraries for AVR architectures that will allow me to transfer data through Bluetooth via dealing with Services, Characteristics, Descriptors, etc.?

The Beetle Bluno BLE board is based on:

• ICSP1: ATmega 328P
• ICSP2: CC2540

• Juraj: ArduinoBLE is not compatible with CC2540. the CC2540 on Bluno Beetle has AT commands

Answer 1

The device is not an Arduino device (Uno, Mega, Nano, Mkr, etc) and ArduinoBLE was made only for Arduino devices with built-in Bluetooth.

• Juraj: it is an Arduino, just the BLE IC is not supported by the ArduinoBLE library
