BLE with the arduino framework
-
We are using the M5core2 and we want to run a BLE-based application using the Arduino programming framework. We download the library for the ESP architecture: https://www.arduino.cc/reference/en/libraries/esp32-ble-arduino/
But, it seems that the library is not compatible with this architecture. We got the following error when initializing the library.

Rebooting...***
Does the M5core 2 support the BLE communication? Is there any Arduino-based library to handle the communication?
We have tested the library with the M5stack core hardware and it run properly.

Hello. Not sure if you managed to get this working yet, but if not, there is a ble library that ships with M5Stack Core2 Arduino install.
#include <BLEDevice.h>
on my computer this was installed at this location: .//Library/Arduino15/packages/m5stack/hardware/esp32/2.0.3/libraries/BLE/src/BLEDevice.h
Hence I did not have to install the package separately.
I have implemented a project using this just recently using a variety of BLE technology so confident that it works on at least my copy of Core2.If you go to the docs link from the library link you posted (https://github.com/nkolban/ESP32_BLE_Arduino) you can see that the project has now been directly incorporated into Arduino. The lib version you may have downloaded may be out of date. You can find BLEDevice.h/BLEDevice.cpp on your machine and check against the main Arduino source.
Hope this helps?
