Samuele Cornell / Mbed 2 deprecated MIDI-to-BLE-MIDI-bridge

This program enables a RedBearlab nRF51822 to be used as a "bridge device" with full bi-directional communication between MIDI through standard MIDI cables and BLE-MIDI. MIDI cables are connected to the UART. This allows for example to send MIDI data to synthesizers directly from a computer or a tablet via BLE-MIDI and vice-versa, "wires-free" . The Midi Manufacturers Association BLE-MIDI Specification is used. This project is inspired by Matthias Frick's "blidino" project which implements a USB-MIDI to BLE-MIDI bridge with the nRF51822 and is available at https://github.com/sieren/blidino. I owe to him all the BLE-MIDI to MIDI parsing part.
