Title: send UDP subnet broadcast
Post by: cmalan on February 29, 2016, 04:10:15 PM

Hi
I am tying to send a udp broadcast to 192.168.0.255, but I don't see it with wireshark. If I use 255.255.255.0 for the IP it does send.
It looks like uTasker is looking for a apr entry for 192.168.0.255.
What must I do to be able to send to this broadcast address

uTasker 1.4
MCF52259

Regards
Christo

Hi Christo

Make sure that you have the subnet broadcast transmission enabled by using
#define SUPPORT_SUBNET_TX_BROADCAST
This support was added on 15.08.2012 so check in your ip.c, and arp.c file headers to ensure your version has it.
Also icmp.c allows pinging the subnet broadcast from 9.9.2012 to see how many nodes respond back.
