I am using a ConnectCore 9P 9215 with NET+OS 7.4.2.
I am have problems broadcasting on the local subnet only, using sendto() as I get an error - No such file or directory. I can broadcast to 255.255.255.255, but for a /16 prefix I can't send to the host broadcast address without an error, for example 192.168.255.255.
I have tried binding to the local IP address and port number and also setting the SO_DONTROUTE option, but these did not help.
Anyone who has had similar problems and knows a solution please let me know!
