Hi,
I am using LWIP version 1.3.2, ATMEL UC3A port with freeRTOS.
I have to develop an application that acts as a server listening for a connection from a client.
Each of the clients is setup to connect to the server using the exact port number.
Example:
Client1 -> Connects to 192.168.0.1 port=1234
Client2 -> Connects to 192.168.0.1 port=1234
Client3 -> Connects to 192.168.0.1 port=1234
Under freeRTOS I have created 3 Tasks, each of the Tasks, bind and listen for a connection on port 1234.
Here is my problem.
When Task 1 is created it binds and listens to accept a connection from port 1234 using netconn_accept, this works fine.
But when Task 2 and 3 are created to listen to the same port, netconn_accept returns an error:
LWIP_ERROR("netconn_accept: invalid acceptmbox", (conn->acceptmbox != SYS_MBOX_NULL), return NULL;);
How do I resolve this problem.
Kind regards
