    Hi,

    There no API for such purpose at CC3200 host driver. You can count number of socket by yourself when you using (sl_Open and sl_Close API) but your will not be able determine whether socket was closed by opposite side.

    Why you need to count number of opened sockets?

    Hi,

    CC3200 supports up to 8 sockets. Two of them can be secured (SSL/TLS).

    If you need more sockets, you should cosier to use CC3220 (16/6) or CC3235/CC3230 device (16/16). CC3220/CC3235 supports also linger option for closing socket, which allow to better management of sockets.

    update: But if you want to stay with CC3200 device, reasonable way how to overcome issue with number of secured sockets is to wait 10sec before opening new secured socket after calling sl_Close() API. This will be enough time for closing socket by timeout even secured socket was not closed by opposite side.

    Hi Linga,

    I agree with Jan's answer, but I also wanted to add that the SL_ESECTOOMANYSSLOPENED error is not fatal. You can check for this error when you create a new socket, and then wait for a few seconds before trying again.

    Best regards,

    Sarah
