our company uses the WizFi250 module with the official
FW version/HW version
220.127.116.11/WizFi250 Rev 1.0
We use the "SOCKET Extension Option"
FSOCK=6,0 (no auto-reconnect) when connecting as “TCP Client Normal” with command
and FSOCK=6,20 when activating TCP Listening Server with
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?
