+		To programmatically establish a Bluetooth MIDI driver connection to a LE MIDI peripheral,
+		the following steps must be completed in order.
+		
+		1. Using CoreBluetooth API, scan for the peripheral's advertised LE MIDI service.
+		2. Using CoreBluetooth API, connect to the desired advertised peripheral.
+		3. Upon successful connection, call MIDIBluetoothDriverActivateAllConnections.
+		4. Using CoreMIDI API, confirm the peripheral's registration by locating its MIDIDeviceRef.
+		5. If present, CoreMIDI now owns a connection the peripheral.
+		6. Using CoreBluetooth API, disconnect from the peripheral now managed by CoreMIDI.
