UDP Broadcast address problem
xAPPO last edited by xAPPO
If I use an address of say 192.168.1.255 with udp.send to broadcast a message to my subnet, or anything ending in 255, I am getting the following
Error: EACCES (permission denied)
Specific non broadcast IP address do work.. and RX is working OK from broadcast. What am I doing wrong ?

bind, followed by
setBroadcast(true)on the socket. Then you can send messages using
FYI, the API is made to be compatible with Node.js API https://nodejs.org/api/dgram.html.
