This demo shows how to run a BLE MIDI Service
You should be able to connect to the Bluetooth MIDI Interface with your computer.
E.g. MacOS: in Audio/MIDI Config, MIDI Window, press Bluetooth Configuration button: the "MIDIbox" device should show up, and you should be able to connect.
The demo will send Note On/Off messages each second, in addition, incoming MIDI messages will be loopbacked
Re-usable component is located under components/blemidi - please see the README.md for programmers there.
Please optimize the app configuration with "idf.py menuconfig":
- Compiler Options->Optimization Level: set to -Os (Release)
- Component Config->ESP32 Specific: set Minimum Supported ESP32 Revision to 1 (if you have a newer device...)
- Component Config->ESP32 Specific: set CPU frequency to 240 MHz
- Component Config->FreeRTOS: set Tick rate (Hz) to 1000
