Utility class for MIDI over Bluetooth LE

Dependencies:   BLE_API mbed nRF51822


Using MIDI over Bluetooth LE

This class enables sending and receiving MIDI packets.

Set up an "BLEMIDI" class instance

Create an instance, and set up to start using it.


#include "mbed.h"
#include "BLEDevice.h"
#include "BLEMIDI.h"

BLEDevice device;
BLEMIDI bleMidi(&device);

void disconnectionCallback(Gap::Handle_t handle, Gap::DisconnectionReason_t reason) {
    bleMidi.onBleDisconnection(handle, reason);

void connectionCallback(Gap::Handle_t handle, Gap::addr_type_t type, const Gap::address_t addr, const Gap::ConnectionParams_t *params) {
    bleMidi.onBleConnection(handle, type, addr, params);

int main(void) {
    for (;;) {

Changing the device name

The default device name is 'MIDI'.
If the another name is preferred, use this constructor. The maximum length of device name is 4 bytes.

Constructor with device name

BLEDevice device;
// BLEMIDI bleMidi(&device);
BLEMIDI bleMidi(&device, "NAME");

Sending MIDI events

For example, send a note on event:

send a note on event

bleMidi.sendNoteOn(0, 63, 127);

About other events, see the BLEMIDI class reference.

Receiving MIDI events

For example, receive note on events:

receive note on events

void onNoteOn(uint8_t channel, uint8_t note, uint8_t velocity) {
    // do something with Note On event


About other events, see the BLEMIDI class reference.
