MIDI (through standard 5-PIN DIN MIDI cables) to BLE-MIDI bridging with Arduino-compatible boards project.

This project was inspired by [Matt Sieren (sieren) blidino Arduino USB-MIDI to BLE-MIDI project] (https://github.com/sieren/blidino). I would like to thank him because his work made this possible as all the BLE-MIDI to MIDI parsing part is taken from his blidino project ( see BLEParser.h ).

The purpose of this project is to allow MIDI devices that doesn't support USB-MIDI (vintage synths for example) to communicate wires-free through the Midi Manufacturers Association MIDI over Bluetooth Low Energy (BLE-MIDI) protocol.

RedBearLab nRF51822

Currently the only board supported is the redbearlab nRF51822 Arduino-compatible Board.

This repo contains the code for the Arduino IDE but as this same board supports mbed OS ( see redbearslab nRF51822 description ) the program was originally developed using that platform (mbed Compiler) .

Also currently this Arduino IDE port here lacks of uart software buffering it should be ported in the future from the original program.

###As such i recommend, for now , to use instead the mbed OS version available here MIDI-to-BLE-MIDI-bridge (mbed OS).

#BLE-MIDI

The Midi Manufacturers Association MIDI over Bluetooth Low Energy (BLE-MIDI) Specification is available, upon free registration, here at Midi Manufacturers Association official site: https://www.midi.org/specifications/item/the-midi-1-0-specification.

Alternatively as the Midi Manufacturers Association de-facto adopted Apple BLE-MIDI Specification one can consult: Apple Bluetooth Low Energy MIDI Specification

This program can also be used to enable a Windows/Linux machine to communicate with BLE-MIDI hardware. There is no need for additional hardware only the board and a micro USB cable. The PC must run a Serial to MIDI software such as Hairless MIDI Serial. Also a software which enables multiple virtual MIDI ports is required on Windows such as loopMIDI.

Note: as MIDI standard 31250 baud rate is not supported by USB ports ( but there are workarounds especially in Linux ) change BAUD_RATE in config.h to a more common value for USB.
