nrf7002 provisioning sample - wifi_nrf_disp_scan_zep: rpu_ctx_zep is NULL

[rf]

I would like to test he Wi-Fi Provisioning Service sample (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/wifi/provisioning/sample_description.html)

sdk v2.2.0 or v2.2.0 rc1

A use the app on android nrf Wifi provisionner.

When I request a provisionning with app I have "Scanning error Received error responce"

and on debug uart "wifi_nrf_disp_scan_zep: wifi_nrf_disp_scan_zep: rpu_ctx_zep is NULL"

see full log :

Hi Remi,

It might be that you have the revision A of 7002 board. You could check if the option nRF7002 Rev A is set in nRF Kconfig configuration. You can access this option by going to VS Code -> Actions -> Kconfig -> right click on Kconfig -> Configure -> then type 7002 in search box -> Device Drivers -> nRF7002 Rev A.

Best regards,
Dejan
