TRRS connector is used for connecting speaker and microphone to FM device. Communication is
half-dulpex, so you can’t listen and speak at the same time (you have to use a switch). To initialize
a conversation - you need to call from your phone to SIM card number, which is inside the device.
Device will automatically answer this call. More information about TRRS is stored in TRRS
connector specification.
