The callback functions NoteOn and NoteOff are not working in my short program. I used the example 03-Receiving Data as is. After some issues with incompatible versions I compiled the last version of ESP32-BLE-MIDI (0.3.2) with NimBLE-Arduino version 1.4.3 as suggested in another post here. The callback function for controller change seems to work. Sending commands note on or note off is also working fine. My hardware platform is M5STACK-core. Has anyone an idea how to solve?
