Original question:

CC3200: sl_WlanGetNetworkList is returning only one AP

CC3235S: How long does one network scan cycle take?

Hi,

I want to get complete list of networks as soon as possible after starting network scan.
How long should I wait after I enable SCAN POLICY?

BR,

Masashi

    Hi Masashi,

    If there are no scan results available yet (or if they are old), calling sl_WlanGetNetworkList() will immediately trigger a one-shot scan and return. You shouldn't have to set a delay in the application.

    Best regards,

    Hi Sarah,

    Thank you.

    sl_WlanGetNetworkList() sometimes return empty list or few APs even though there are many APs around.

    In particular, it seems that 5GHz APs are often missed.

    Setting the channel mask did not change the situation.

    Is there a solution to this?

    Best Regards,

    Masashi

    Hi Masashi,

    (Edited) Please try using sl_WlanGetExtNetworkList(). This should scan the 5GHz channels by default.

    Is the latest servicepack version flashed to the file system? Is 5Ghz enabled? (This can be done in the application or in the radio settings in ImageCreator.)

    What channel is the desired network on? What country code is being used?

    Keep in mind the network list will only returns APs with a RSSI above the threshold (default -95 dBm), and the network list is filled at 30 entries.

    Best regards,

    Sarah
