Hi I am trying to Implement an artnet decoder using the new ethernet interface.Some functions of artnet require the use of broadcast packets but the udp socket doesn't seem to recognise them

if I set the the ip to a static address and run the example udp server it will print received packet from and my ip address quite happily but if I try to sent a packet with a broadcast address of 2.255.255.255 it will ignore this

is this a bug or something that hasn't been planned for ?

could I also add a +1 for the ability to send a broadcast packet from the mbed

many thanks for your time

Just revisited the mbed site to check on any Ethernet library progress and great news - a new library :-)

So tried it out for my UDP broadcast needs and immediately found this same problem. Is this going to be fixed (TX and RX) or am I back to my other development platform ?

A while back I had to figure out how to do UDP broadcasts myself. see https://mbed.org/forum/bugs-suggestions/topic/3921/ I've not yet progressed far enough to deal with receiving broadcasts, and had assumed they'd just work.

Also, take a look at this project I did to do UDP broadcasting; https://mbed.org/users/nkhorman/code/Test_Udp_Broadcast/

We added support and examples for Broadcast and Multicast:

• Broadcasting
• Multicasting
