Bluetooth Broadcast Audio Technology

Hi Guys,

I am doing some research into qualcomms "Broadcast Audio Technology" in order to link multiple portable speakers together. (Much like JBL does with their connect system)

I am looking into the CSR8675 Bluetooth SoC but cannot find any real source of documentation explaining how to enable the Broadcast audio mode on the chip or how to use it.

The most I have found is to short the "KeyCom" pin to the "Prev" pin to enter transmitting mode and thats it!

If anyone could shed some light on if this sounds correct or how to enable/use broadcast audio between 2 CSR8675 chips, it would be greatly appreciated. Or if anyone knows of any better bluetooth modules to use or a different way of linking multiple bluetooth modules together then I am all ears.


Thanks!
