We have developed a gateway that sends data gathered from some devices
to a server. Via LAN -> WAN this works fine and reliably for months
without failure. Now a customer has connected a GSM rounter instead. In
principle this works, too. But after a not predictable time (minutes,
hours, ... ) the GSM-router locks. When trying to establish a
TCP-connection via "netconn_connect" I get -10 (connection aborted).
I don't see how I could change the behavior for the connect command --
either it works or it does not. Actually I think the problem is with the
GSM-router, but may be, just may be anyone knows a trick or a special
consideration to get rid of this connection problem.
The connection gets closed after each transmission and the repetition
rate is about 5 minutes. Thus the amount of data cannot be the problem.
Thanks for any hint!
