Hi Team, I am working on TCP webserver on mbed. The Wizfi 250 module connects to AP and obtains the IP address, then I SCON command for TSN socket and then MEVTMSG command which give error. After this When I try to check loading the IP address on my mobile, it doesnt display the HTTP response that I am sending from the application. I checked the console, but dont see any response. Following are the output on console, Command = AT [OK] Command = AT+MECHO=0 [OK] Command = AT [OK] Command = AT+WNET=1 [OK] Command = AT+WSET=0,testAP [OK] Command = AT+WSEC=0,password [OK] Command = AT+WJOIN Joining : testAP Successfully joined : testAP [Link-Up Event] IP Addr : 192.168.43.94 Gateway : 192.168.43.1 [OK] Command = AT+WSTATUS IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) STA/testAP/192.168.43.94/192.168.43.1/00:08:DC:51:3D:B6/31/55 [OK] WIFI connected to hotspot The target IP address is ‘192.168.43.94’ Command = AT+SCON=O,TSN,80,0 [OK] Command = AT+SMGMT=?

I think your WizFi250 firmware does not support the command. So, I recommand you to use latest firmware !![:slight_smile:](https://emoji.discourse-cdn.com/twitter/slight_smile.png?v=12) it is available below Thanks, --- Source: https://maker.wiznet.io/forum/12486
