İpv4 udp socket creating problem

I have adapted udp sock example in docs to ipv4 version.

However i am getting " Error creating UDP sock " problem. I could not figure it out why.

This is the cliend side code. In docs example i have successfuly run it in ipv6 and in java i received messages at server side.

Hardware: Board=esp8266-esp-12x

Thanks for your help


GNRC does not support IPv4. Check out lwIP [1] as an alternative that supports that protocol.
