Hi,
I have write a service on my STM32F4 microcontroller board that listen
to port 1000 and 2000 using the rawsocket(without rtos) and lwip-1.3.2.
After i have write a client program for pc that connect to this ports
and every 100ms read data from it, but after 30/40 second of perfect
work the rawsocket of the lwip seems don't work, so the pc client after
timeout(10sec) disconnect the communication, and retry to connect.
With wireshark when the port seems lock i find this error:
8670 117.669053 172.30.1.237 172.30.1.20 TCP [TCP
Retransmission] 61949 > sightline [PSH, ACK] Seq=7610 Ack=1030698
Win=64240 Len=6
Do you have same suggestion for solve this disconnection?
