Bluetooth Transmitter

Hey Guys,

is it possible to transmit the audio signal via bluetooth to some speakers?

Yes. The easiest way to do this would be to purchase a bluetooth transmitter that will plug into the analog audio output of the Pi or a DAC with analog outputs, and use that to connect to the speakers.

(I do this all of the time to listen to the TV on bluetooth earphones.

Yes, it is possible but you need to pair the Bluetooth devices
