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)
