    AP Scan Power consumption

      Hi,

       

      I am using SN8205, SDK3.1.2.

       

      My device is battery powered and frequently scans APs.

      The current consumption for a AP scan operation using wiced_wifi_scan_networks() is 157mA over 1.5 seconds.

       

      Is there any way to optimize and reduce this power consumption?

       

      Should I use WICED_SCAN_TYPE_ACTIVE/WICED_SCAN_TYPE_PASSIVE?

      Does wiced_wifi_scan_networks() have upper bound on the time it takes to scan? Currently it is 1500ms.

       

      Regards,

          Hi Karthikeyan,

           

          We have an application called ping_powersave under snip and also an application note. Let us know if you require more info related to this.

           

          Also WICED_SCAN_TYPE_PASSIVE should help you. If you look into wwd_wifi there are scan_params

            scan_params->params.active_time 

             scan_params->params.passive_time

           

          these should help you to change the time it takes to scan.
