UDP receive issue

Hi,

I can't receive the UDP packets sent from SockTest (SERVER) to the Wi Fi module (CLIENT).

I connect the Wi Fi module via TeraTerm, configure it and then sent an "AT+S.SOCKON=192.168.32.255,4999,u,ind" to prepare the Wi Fi module to listen for udp packets.
Now, from SockTest, I sent a message to 192.168.32.255 (or the specific IP of theWi Fi module) / port 4999 but I don't receive nothing (I should receive the WIND:55 indication).

I try to test even with the CubeExpansion WIFI1 V2.1.0 - Client_Socket firmware for IAR, the sent function is OK but I can't receive the message from the Server (SockTest ) on the Wi Fi Module.

I only change the protocol from "t" of TCP to "u" UDP.
If I use the with TCP protocol it work well.
I need to have the UDP packets receive.

The FW is 160129-c5bf5ce

Regard.
Stefano.
