I was looking for a way to connect to several wireless clients(by Bluetooth preferably) and send data to them all at once(, not simultaneously). I was interested to use esp32 or esp8266, to connect to bluetooth speakers and stream audio to all of them in order to sync them. But I realized it can only talk to one client at a time.

Can you suggest some other options to do so? Would SPI master slave style connection work?

Thank you

 

Being it is just audio and you could handle some bit errors without issue, I would recommend one way UDP protocol.

 

There is a standard that applies to your problem. Search for “Audio over IP”

Okay I will search into that. Thank you !

So not possible for bluetooth?

I did and it does look promising, Thanks!

 

The HC-12 digital radio module is generally used like Bluetooth, with 2 units connected, but it actually can have "one master, many slaves" as long as only 1 unit transmits at a time.

That is pretty much what I want. Thank you let me research on that too
