CC3200MOD: When Working as AP mode and is connected to a station, how does the other station know CC3200 at AP mode is connected?

Dear sir,

    Our device works as an access point by the help of CC3200, working at AP mode.

When it is connected to a station, say tablet A, other tablets are not allowed to connect.

The question is: how shall the other tablets check to know that CC3200 at AP mode is already connected so that it can prevent from trying to connect to the AP mode CC3200?

Thanks for your time.

Best Regards,

Luke

    Hi Luke,

    I think there is no way how your tablet can detect that AP in CC3200 is occupied by another client. You have this information available when your connection attempt to CC3200 AP failed.

    I think best way is to migrate to CC3220 which supports up to four clients in AP mode.

    Dear Jan,
    Thanks for the reply. When CC3200 as AP mode is occupied, and some other station tries to connect, what kind of failure shall the station get?
    Authentication error or time out error? Is there any event, for example, when the station is running on the Android platform?
    On the other hand, is there any guidance help us to transfer the code for CC3200 to the code for CC3220? Could you show us the way to migrate to CC3220?

    Thanks for your time.

    Best Regards,
    Luke

    Hi Luke,

    I am sorry, I am not familiar with Android connection APIs. I am not able to answer your question. Maybe someone from TI team will know more. But if you know how to use Android connection APIs, you can easily check this by yourself.

    Migration from first to 2nd generation depends on how your code is designed, but according my experiences is relatively easy. Latest migration guide you find here ( dev.ti.com/.../SimpleLink_Gen1_to_Gen2_SDK_Migration_Guide.html ) or at CC3220 SDK. Changes in brief:

    - some sl_ APIs was changed (generally it is only about "syntax", philosophy of SimpleLink APIs is still same)
    - peripheral drives was changed from driverlib to RTOS driver (driverlib is still there and can be used)
    - OS abstraction layer was changed from osi.h to POSIX layer (after small changes at osi layer from CC3200, it can be used)
