UDP communication through ESP-Link #442

Are the ESP-Link from Jeelabs or any of it's forks able to comunicate using UDP protocol ? If so, how to configure the ESP-Link to use UDP instead of TCP ?

I see this is more complicated than I thought. I'm trying to send binary data from Matlab to Arduino via ESP-link. To change protocol in Matlab it comes down to changing function name from tcpip to udp, and to be honest in case of ESP-Link I have no clue how to use this example just to read the binary data. But thanks anyway.

maybe this example is too complicated but you need

int err = udp.begin(udpServer, udpPort, SOCKET_UDP, udpCb);

and udpCb for. data receive

Thank You, I will try.

maybe you can also check ELClientSocket.cpp for clue, you can find there some examples
