completely exhausted with idea of auto-pairing, after about month of extreme struggle - i did it, but only for S3, absolutely the same code not working on C3
is there some hardware limitation that i missed?
code are pretty basic, based on https://randomnerdtutorials.com/esp-now ... 2-esp8266/ tutorial
two stages, broadcast 0xFF, getting mac address of peers via callback, add them to peer list and then start unicast stage
broadcasting works fine, but unicast only for S3, tested both way (by one and in group)

Re: esp-now esp32 C3 vs S3
I think you must check the configuration settings in 'menuconfig' for both devices.
