BLEMidi

BLEMidi is a helper class that adds support for sending and receiving MIDI Messages using the MIDI over Bluetooth LE

specification. BLEMidi supports the full standard MIDI protocol (including SysEx messages), and it also can act as the

hardware interface for the Arduino MIDI Library.

API

BLEMidi has the following public API.

Installing the Arduino MIDI Library

BLEMidi is easiest to use when combined with the Arduino MIDI Library. You will need version 4.3.0 or higher installed

before continuing with the example code.

Next, select Communication from the topic dropdown, and enter MIDI Library into the search box. Click the Install

button to install version 4.3.0 or higher of the MIDI Library.

The Bluefruit nRF52 Feather codebase is in an early BETA stage and is undergoing active development

based on customer feedback and testing. As such, the class documentation here is incomplete, and you

should consult the Github repo for the latest code and API developments: https://goo.gl/LdEx62
