Question

Hi all.

I am using an FMB001 and having problem with the tcp data link close delay from the device when it gets ack from the server.

The gprs record setting is: open link time out: 30s, response time out: 30s.

The data acquisition setting on stop / home: min period: 0, min saved records:1, send period: 5

when FMB001 is plugged, server get the trace below. everything is fine but I was expecting the device to close the tcp connection as soon as it get ack from the server, but it takes > 30 sec.

Is there a specific setting so that the device closes the tcp communication right away when it get the ack?  (the server parses data packet on tcp close....)

thank you for your help.

regards.

Denis

Answer 1

and to complète my question, sometimes the tcp close happens very quickly. (cf trace below). by the way, what is this 0 event? can I get rid of this?
