Wi Fi ncs example gremlins ...

[andywe]

I am working through the ncs wi-fi samples on an nRF7002 DK board ...

I can get the shell example to work ... so I know that authentication with my access point (AP) and

DHCP  is working correctly.

When I build and try to run the sta (station) example it hangs at the scanning stage ...

Output from shell example (SSSID and password crossed out) ...

Wifi scan … output

Help and suggestions would be much appreciated, especially some

guidelines and advice on how to troubleshoot this problem.

Hi

Have you set up the IP address, SSID and password correctly in the prj.conf file of your STA project? You need to set the CONFIG_STA_SAMPLE_SSID to whatever SSID you want to connect to, as well as set the security to what level your AP uses with either of the security levels below, and change the CONFIG_STA_SAMPLE_PASSWORD if applicable.

# Below configs need to be modified based on security
# CONFIG_STA_KEY_MGMT_NONE=y
# CONFIG_STA_KEY_MGMT_WPA2=y
# CONFIG_STA_KEY_MGMT_WPA2_256=y
# CONFIG_STA_KEY_MGMT_WPA3=y
CONFIG_STA_SAMPLE_SSID="Myssid"
CONFIG_STA_SAMPLE_PASSWORD="Mypassword"

The prj.conf file is also where you change your IP address if you would like a custom IP address to be set statically.

Best regards,

Simon

I tried this
I also want to set ssid and password but I facing an error: attempt to assign the value '"UH_home"' to the undefined symbol STA_SAMPLE_SSID

[Simonr]

Hi

What sample have you added this CONFIG in? It needs to be set in the Kconfig file and in the nRF Connect SDK only the WiFi/STA and WiFi/sr_coex samples have these by default.

config STA_SAMPLE_SSID
	string "SSID"
	help
	  Specify the SSID to connect

Best regards,

Simon

I was trying it on wifi shell sample code
Actually want to set ssid and password through ble, can I do it in wifi shell sample code or need to flash some other sample code?

[Simonr]

Hi

The Wi-Fi shell sample has another way of working with the Wi-Fi credentials library, explained in the documentation here. You can use wifi_cred add <SSID> <Passphrase> <Band> to add network credentials for an AP in order to later auto connect to it. You will need to add the aforementioned config to set the SSID in your .conf file.

Please create a new case if you need further help, as this is getting out of topic for the initial ticket

Best regards,

Simon
