Just in the lab a bit and I wanted to know if I could use A2DP to create a bluetooth speaker, establish a connection, then receive the audio stream from my phone and send it to my ESP speaker. Once I successfully do that, I would like to use another speaker with ESPNOW & A2DP to receive that signal then mirror it to another speaker.
Essentially one would be a master ESP and the slave ESP's would mirror the audio from the speaker with BT connectivity then play simultaneously on all of the ESP speakers. This would almost be a repeater of the original signal.
