Wi-Fi Combo

Not applicable

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,

Karthikeyan.T

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.
