Arduino-ESP32-Midi-BLE-Proxy

What is it?

This code makes your ESP32 act as a simple proxy which takes MIDI commands from a Bluetooth Low Engergy (BLE) device (like a tablet or smartphone) and sends the MIDI commands out to the gear which is wired to your ESP32. This code uses the Arduino-BLE-MIDI library in Version 2.1.0. Also the ESP32 core (board) is needed like described below.

Hardware

Compile

You can compile the source code like any other Arduino sketch by using the Arduino IDE. If you like you can also use VSCode in combination with the Arduino plugin. A matching board configuration is available in .vscode/arduino.json.

1. Create a directory MIDI_BLE_PROXY and clone this repo

   mkdir MIDI_BLE_PROXY
   cd MIDI_BLE_PROXY
   git clone https://github.com/R0Wi/Arduino-ESP32-Midi-BLE-Proxy.git .

2. Copy the content of the lib folder into your Arduino libraries folder (for example to ~/Arduino/libraries). This will ensure that the Arduino-BLE-MIDI and it's dependencies are correctly installed on your system. Alternatively you can download the Arduino-BLE-MIDI version 2.1.0 through the Arduino IDE library manager using this link: https://www.ardu-badge.com/BLE-MIDI.
3. Open Arduino IDE and install ESP32 board

   

This step will also install the BLE core libraries from https://github.com/espressif/arduino-esp32/tree/master/libraries/BLE used in the sourcecode. Read more about boards here.

3. Under Tools->Board choose DOIT ESP32 DEVKIT V1
4. Compile & have fun.
