Re: [lwip-users] TCP Sockets Simultaneous Read andWrite

[PeterAdamsen]

Doing some more testing I have found that it isn't the Simultaneous Read and
Write that causes the pause.

It is the situation where the microcontroller received more than 7 messages
without being able to read them.

Sending more than 7 message to the loop below, will cause TCP
retransmissions, and large delays on PING's



   while (1)
   {
     lwip_read(sock2, str, 6);
     delay(5000);  // 5 sec
   }
