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

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
