Summary
Currently, BluetoothSerial makes it impossible to run both arduino-esp32 and NimBLE.
How to reproduce the original problem
esp-idf version: release/v4.4
arduino-esp32 version: 2.0.1
Steps:
idf.py menuconfigComponent Configuration / Bluetooth / Bluetooth Hostand set it toNimBLE.Impact
This Pull-Request makes it possible to use arduino-esp32 with NimBLE, by making the compilation BluetoothSerial optional. To fix the issue, you thus need to:
idf.py menuconfigArduino ConfigurationInclude only specific Arduino librariesEnable BluetoothSerialWe could probably, additionally, make that option depend on the BLE host, but I'm not sure how to do so, nor whether it's a good idea to.
