For directed messages everything works fine, but it seems that broadcast is completely \"ignored\" by the ESP8266...\r\nIf 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).\r\nOn 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)...\r\nI sniffed with wireshark, but the ESP doesn't send anything, if I use \"192.168.1.255\" as ip.\r\n\r\nHas anyone any idea how to fix that?\r\n\r\nI am currently using ESP Version 2.0.0 rc-2.\r\n\r\nAny thoughts on this are welcome, thank you!"},"comment":{"url":"https://api.github.com/repos/esp8266/Arduino/issues/comments/161600512","html_url":"https://github.com/esp8266/Arduino/issues/1134#issuecomment-161600512","issue_url":"https://api.github.com/repos/esp8266/Arduino/issues/1134","id":161600512,"user":{"login":"me-no-dev","id":12663778,"avatar_url":"https://avatars.githubusercontent.com/u/12663778?v=3","gravatar_id":"","url":"https://api.github.com/users/me-no-dev","html_url":"https://github.com/me-no-dev","followers_url":"https://api.github.com/users/me-no-dev/followers","following_url":"https://api.github.com/users/me-no-dev/following{/other_user}","gists_url":"https://api.github.com/users/me-no-dev/gists{/gist_id}","starred_url":"https://api.github.com/users/me-no-dev/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/me-no-dev/subscriptions","organizations_url":"https://api.github.com/users/me-no-dev/orgs","repos_url":"https://api.github.com/users/me-no-dev/repos","events_url":"https://api.github.com/users/me-no-dev/events{/privacy}","received_events_url":"https://api.github.com/users/me-no-dev/received_events","type":"User","site_admin":false},"created_at":"2015-12-03T11:08:28Z","updated_at":"2015-12-03T11:08:28Z","body":"what is the size of the broadcast packet that you want to send?\r\nRecently the starting size of the UDP buffer was reduced and I experienced such things trying to broadcast packets larger than that initial buffer."}}
