UDP例子
I find that UDP works very well and had one transmitter and multiple receivers running for over 18 months.

Broadcast is not very reliable. Sending Unicast would be much better, but you would need to send once to each ESP.
This would be a good starting point. You would not need the reception part, just send duplicate the send.
