Hi,my embedded application send to Cosm some sensor data every 15 secs. Everything works fine for about 20 connections. At some point there is a TCP retransmission due to, I am supposing, a missing ACK. After that no data is received from the Cosm Server and the connection doesn't complete properly.
In attach the pcap captured for the connections. Any suggestions is welcome. I am using lwip 1.3.2. Thanks Jaws
