7002 scan parameter

[William.wei]

hi support team,

customer is asking about how to using 7002 to scan 2.4g wifi or 5g wifi only, and want to know if 2.4g only will accelerate the scan duration time.

i could not find the parameter to set this for scan_info. and want to know exactly the coding if possible from Nordic 7002 side

Regards,

William.

Hi William

What times do you measure here where you decide it's using the passive scan parameter? From scan requested to scan request complete there are multiple seconds in these screenshots, and from num ID to scan request done it seems much closer to the ACTIVE parameter of 50ms. That being said, are you sure these time stamps come from the application and not the logger, as the logger/serial port setting the timestamps will not necessarily be the correct times of when this occurs.

From the snippet you share, the default channels that are used to scan on the 5GHz band are channels should be channels 36, 40, 44, 48, 149, 153, 157, 161 and 165 on the 5GHz band when you set the 5GHz band only. I'm not sure I understand what you're asking as the logs you share also seem to coincide with these channels.

Best regards,

Simon

Hi Simonr，

could you please try ncs2.5.0 wifi demo :\v2.5.0\nrf\samples\wifi\scan

and default parameter is:

CONFIG_WIFI_MGMT_SCAN_DWELL_TIME_ACTIVE=50
CONFIG_WIFI_MGMT_SCAN_DWELL_TIME_PASSIVE=130

and make change to them, and see which parameter is working.

so far as i tested. we are using passive mode, not active mode, however, in our code it is active;

however, i can see that we set this to active scan:
