- Sun Nov 29, 2015 2:30 pm #35280 Has anyone tried to receive and send broadcast messages over UDP? I am using the module for receiving Artnet messages. For directed messages everything works fine, but it seems that broadcast is completely "ignored" by the ESP8266...
If the module has e.g. a localIP of 192.168.1.25, it doesn't receive messages with an IP of 192.168.1.255 (which is used for Artnet Poll Requests).
On the other hand, the ESP doesn't send any packet, that is directed to a broadcast address, although the return values of udp.beginPacket, udp.write and udp.endPacket all are "successful" (1)...
Has anyone any idea how to fix that?

I am currently using ESP Version 2.0.0 rc-2.

Thanks!

- Mon Jan 18, 2016 12:43 pm #39161 I read some where in the forum about this has been fixed in the last version of the SDK.
Look here : http://www.esp8266.com/viewtopic.php?f=18&t=6735&p=35665&hilit=udp+broadcast#p35665
No ArduinoESP version use SDK 150 yet.


We will have to wait.
