Scan for nearby Wi-Fi networks using the nRF7002-DK.

[ChiragBhavsar]

We are using SDK v2.6.1 for our application and would like to search for nearby Wi-Fi networks using the nRF7002-DK.

Could you please assist us with this? If any reference code is available, we would greatly appreciate it.

Hi

Please check out the Wi-Fi: Scan sample available in nRF Connect SDK to see how to do scanning with the nRF7002 DK. Alternatively, we also have the Wi-Fi Shell sample if you want some more runtime configurables using a shell. It also has scanning capabilities.

Best regards,

Simon

thank you for your support,

I used SDK v2.6.2 for the Wi-Fi scan sample.

Currently, I can read the scan data only once. How can I modify the code to read the data at regular intervals? Below are the logs for your reference.

Scan requested

Hi

The wifi_scan(); function is only called once in the main() loop, so you'll need to change how it is called by for example repeating the function every X seconds or so.

I thought the wifi_scan() function in the Wi-Fi scan sample code was being called at regular intervals because the message 'Scan requested' is printed inside the wifi_scan() function.

However, the NET_EVENT_WIFI_SCAN_RESULT event is triggered only once. How can I ensure that the callback enters the NET_EVENT_WIFI_SCAN_RESULT case repeatedly?

case NET_EVENT_WIFI_SCAN_RESULT:

handle_wifi_scan_result(cb);

Hi

Ah, okay. Sorry about the misunderstanding. Yes, this is handled in the wifi_mgmt_event_handler() and it will return the scan_result or scan_done event depending on the callback. I guess you can change it to always return the scan results instead of the "DONE" message if you'd like, or to add results to the handle_wifi_scan_done() function.

Best regards,

Simon
