Tool/software: Code Composer Studio

Hi,

I am getting the error in sl_NetAppDnsGetHostByName() function which is causing to disconnection with server again and again.

lRetVal = sl_NetAppDnsGetHostByName((signed char *)host_name, strlen((const char *)host_name), &g_ulDestinationIP,SL_AF_INET);

The error is close socket (241) operation failed to transmit all queued packets.

Can I know why?

Thanks

Hi Black_Robot,

What server are you using here? Can you try another server and get the same error?

Best regards,
Sarah

Hi,

I am getting the same error with other server also.

I think that it should not be happen but it is happening again and again.

That's why I want to know the reason.

Hi Black_Robot,

Socket error codes are in socket.h. -241 is SL_ESEC_LENGTH_ERROR or record layer length error, which I would not expect with a non-secured socket.

What servers are you trying? Do basic websites like google.com work for you?
Please try testing with the getting_started_with_wlan_station example. You can change the HOST_NAME define at the top of main.c, and this is used for a sl_NetAppDnsGetHostByName call once the device connects to an AP.

Best regards,
Sarah
