TM4C1294KCPDT: Ethernet communication issue

Yuvaraj V

Part Number: TM4C1294KCPDT

Hi,

I am using TM4C1294KCPDT for my application, in that i am developed code for Ethernet TCP/IP socket communication based on Ti-RTOS examples.

Communication working good always. I am configured my board as Server.

I need a add on on this, in my code whenever data received on TCP/IP, controller generate the receive task.

inside same task i am able to send reply data to client. Once i come from the task, not able to send the data to client.

Some times i need to send the data without any request from client, but first time client creates the connection with my board with new enquiry.

Regards,

Yuvaraj

Hi,

I'm not clear with your question. Are you referencing the tcpecho example? This example will create the tcpWorker task after the server accepts the client connection. Once the tcpWorker task started, it remains in the task waiting for data to receive from the client and then echo back. This is basically how it works. If you want to send something to the client, you can create another task that calls the send command.

Hi,

My issue is after receiving data my code entered to receive task.

Inside the receive task I am able to transmit the data using send task.

But I am not able to send data outside the receive task using send command.

Hi,

Can you try create a different task and issue the send command in that task. You may need semaphore between the tasks or some type of task_sleep inside the task so that kernel can switch between the two tasks.
