Compiler/CC3200: [SOCK ERROR] - close socket (241) operation failed to transmit all queued packets and post status -112.

Hi,

Do you always get '241' in the async socket error handler? That number is actually not an error number, but it refers to the socket handle which had the error. Are you performing an sl_Close() right before getting that error? It typically occurs if you try to close a non-blocking socket before the network processor has time to send out all of the data queued from an sl_Send(). Try putting a small delay before closing your socket and see if that fixes things.

As for the HTTP error, what do you mean when you say that you are getting this for some devices but not all? Are you testing with multiple CC3200 devices? If so, I would make sure that all of the CC3200 boards have the latest servicepack flashed on them. Another thing to try is to perform your POST to another server, and seeing if it also fails with the same error. If it doesn't fail when POSTing to another server, then the problem might lie on the server side.

Hi,

Yes, I am getting always '241' in the async socket error handler. No, I am not performing any sl_close() function. I am using to the function HTTPCli_construct(httpClient)  and HTTPCli_connect(httpClient, (struct sockaddr *)&addr, 0, NULL); and I am using HTTPCli_disconnect(&httpClient); HTTPCli_destruct(&httpClient); HTTPCli_delete(&httpClient); for closing. I have given the small delay between connection and dis-connection.

I am not using any sl_Send() and sl_Close() function.

Please let me know "how can I rectify this issue" because my device is hanging after this socket error.

Thanks

Hi Black_Robot,

The underlying implementation of HTTPCli_connect() will perform sl_Send() and likewise the implementation of HTTPCli_disconnect() will perform a sl_Close().

Just to clarify, are you performing many HTTP requests in your application before the error occurs, or does it happen immediately on the first request you try to perform? Also, can you please clarify the following from your previous posts:

1. What do you mean when you say that you are getting this for some devices but not all?
2. Are you testing with multiple CC3200devices? If so, I would make sure that all of the CC3200 boards have the latest servicepack flashed on them.
3. Have you tried performing your POST to another server, and seeing if it also fails with the same error? If it doesn't fail when POSTing to another server, then the problem might lie on the server side.
