CC3220SF: Simplelinkevent for FIN command

Snr93

Part Number: CC3220SF

Hi!,

I receive a FIN command from the server to a CC32XX device.

Which member in the structure "SlSockEvent_t" should be checked for to identify which socket descriptor received a FIN command ?

Thanks!

Hi,

CC32xx devices does not have such feature. You can check if socket was closed, but there is no API for direct interaction with FIN packet. Only way will be bypass TCP/IP stack inside NWP and use own TCP/IP stack inside application processor.

Hi,

If the TCP socket is closed by peer device, you should get 0 as the return value from calling sl_Recv().
