Best product for a simple bluetooth speaker with sound active detection?

[Loodio]

Hi,

I am looking for your simplest product that supports this use case:

When bluetooth is paired with a device, and music is NOT playing after a certain time, I want to be able to detect this with my MCU and then switch to another music source.


Requirements:

-Pairing of several units
-Save settings in memory when off
-Stream good enough quality for small 3W speakers


Can someone guide me?

Thanks
Carl
