hello, can esp8266 receive espnow broadcast messages? all my tests show that it can't do it, at least in case of esp32 sender.
Documentation says that 8266 couldn't use multicast and broadcast until some release but that's in the past. Now 8266 can work in unicast mode and transmit broadcast messages but not receive them... It's really strange, there is no big difference between frame transmitted in unicast and broadcast mode (my opinion). And second question - is there a way to disable acknowledgment for unicast - maybe disable encryption?

Disabling acknowledgment for unicast is not directly supported in ESP-NOW, but disabling encryption might provide a more broadcast-like behavior without ACKs.
