Re: [lwip-users] netconn_write/recv from two different tasks..

Hi Sylvian

Just to be clear.

So I do have todo something like with a small receive timeout for the
netconn:

CombinedTXAndRXTask()
{
      // Do connections handlign
      WaitForLink();
      xNetConn = netconn_new(NETCONN_TCP);
      netconn_connect ( xNetConn, &remote_ip, sPortNumber );

      // Receive and transmite
      while(1)
     {
         // RX
        nReceiveErr = netconn_recv(xNetConn, &buf);

        if(nReceiveErr  == ERR_OK)
        {
             // Recevie all buffers here
             // Handle the data --> schedule some data for TX
        }

        // Any TX
        if(AnyTXData())
        {
           netconn_write(xNetConn, byTXBuffer, ETH_RAW_SIZE, NETCONN_COPY);
        }
       vTaskDelay(1); // 
     }// while loop

}

or is it better to use a semaphore around the netconn_recv and
netconn_write, so no write can be done during receiving and no receive
during wrie?

How does you handle it?
