happily received your message today and tested it immediately:
After installing BT support, the first reboot produced an error (sth. like “Installation went wrong.”) but after a second reboot everything was fine:
I connected a BT Speaker (as receiver) and my tablet (as source).
They both work and even output to my stereo system is correct! (Cirrus/Wolfson card via LineOut).
Great work from you and the others on the team!
Big “Thank You” for implementing this!
