One sender, many receivers #2
Description
Never used ESP-NOW before.... Is there a reason this will not work in the opposite direction? I need the sender to be the gateway, broadcasting to a number of receivers every few seconds.
I have modified the code to have the sender be gateway and the receivers pair themselves to it as peers. Both sender and receiver(s) report correct initialization and pairing (receivers) but the receivers never receive a msg. I tried a broadcast send AND specific MAC address with no difference. Happy to contribute my code if this is possible and I can get it to work.
