Possibility of transmitting to more than 30 receivers?

[BryanWaya]

Can you connect more than 30 ESP receivers to one transfer using ESP-NOW or UDP broadcast system?

He is using broadcast packets. So the number of receivers doesn't count, I think.

with ESP-NOW even if you broadcast i think you need to address the devices (sort of pairing) - i'm not quite sure but i think there is a limit to it at 20 devices. UDP -> there is no limit.

When broadcasting to ff,ff,ff... with esp-now, there is no pairing, no reception ack, the number of receivers is unlimited.

I also confirm, no paring (esp_now_add_peer()) is needed. But as more and more devices are transmitting, the packet loss rate will increase.
As my test, at 200 hz, where will be 22% packet loss. (may vary with interference in the environment and the quality of antenna).
