Audio via Rasberry Pi bluetooth

Is it somehow possible to stream the audio of a Digital radio HAT over bluetooth to a bluetooth speaker?, i do have a Bose speaker who after it´s latest software update became a dumb bluetooth speaker and is out of use since then (Bose decided to terminate the preset stations functionality).

i do see an analog output on the HAT, in the most extreme case i can connect it via 3.5mm jack but i think it must be somehow possible to stream audio via the Pi over BT?.

Yes, this is possible. The Raspberry Pi can capture the radio audio through I2S and send it to a paired Bluetooth speaker.

We will look into adding a Bluetooth Output option to the web interface in a future update.
