LAUNCHXL-CC3235SF: TCP socket automatically connects after power off and restart

Hi team,

My customer want to connect to the server and create TCP socket  automatically when the CC3235SF is power off and restarts.

Is there any way to do it?

Could you help to check it?

Regards,

Kevin

    Hi Kevin,

    To clarify, is your customer trying to reconnect after a full reset, or after just an lpds cycle, or perhaps a hibernate cycle?

    After a reset, the CC3235 MCU and NWP state is cleared, so the TCP socket will be disconnected, as well as your connection to the AP. The customer's code will need to wait for reconnection to the AP (automatic if auto-connect is enabled with a Wi-Fi profile provisioned), then reconnect to the TCP socket manually. There is no option to have the NWP handle the TCP socket for you automatically.

    Regards,

    Michael
