WizFi250 Timeout Settings

Question

Hello, our company uses the WizFi250 module with the official FW version/HW version 1.0.3.3/WizFi250 Rev 1.0 We use the “SOCKET Extension Option” FSOCK=6,0 (no auto-reconnect) when connecting as “TCP Client Normal” with command AT+SCON=O,TCN,,,1 and FSOCK=6,20 when activating TCP Listening Server with AT+SCON=SO,TSN,,1 This works in the laboratory and in field tests. But our customer assumes now that the TCP timeout is to short for establishing TCP connections from Europe to Australia. I can’t prove it, but can measure a rather short timeout on establishing TCP connection of 5 seconds. I tried the command AT+FSOCK=1, with no success. The options 6 and 8 are clearly not what we want. A) Is there a posibility to increase the TCP connect timout? I also could measure a 10 second TCP timeout after sending a packet to a meanwhile disconnected server. B) Is it possible to change this value? Thanks!

Hi, GOHS Can I get some materials regarding your questions? GOHS: I tried the command AT+FSOCK=1, with no success. The options 6 and 8 are clearly not what we want. A) Is there a posibility to increase the TCP connect timout? → How did you use the AT command? Did you try like this? ‘AT+FSOCK=1,15000’ If you didn’t, try like that. Or if you did like that, please attach the screenshot to check the DBG messages. GOHS: I also could measure a 10 second TCP timeout after sending a packet to a meanwhile disconnected server. B) Is it possible to change this value? → I think it is also same things. please try ‘AT+FSOCK=1,20000’ (max.20000ms) Thanks!

Hi, GOHS I misunderstood some parts. There is no way to set a TCP timeout value. As you know, in case of disconnected environment, there is how to reconnect every specific seconds. AT+FSOCK=6,20 → try to reconnect per 20s I am sorry for this. Thanks,

Thanks for the info. Would be nice if the exact timeouts would be mentioned in the WiFi250 wiki. Greetings!
