The protocol **BluetoothTransmitterDelegate** defines functions that allow to pass bluetooth activity information from the
BluetoothTransmitter class to a specific transmitter class. Example when a disconnect occurs, the BlueToothTransmitter class
handles the reconnect but the delegate class can for instance show the connection status to the user. It will be informed about
the connection status via the function centralManagerDidConnect in the BluetoothTransmitterDelegate
