[lwip-users] Raw socket disconnection

[address@hidden]

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?
