[nRF5340 + nRF7002] nRF7002 wifi probe failure on custom project

[Sagar.K]

Hello,

Development Environment :

SDK version: nRF Connect SDK v2.7.0

Toolchain version: nRF Connect SDK Toolchain v2.7.0

Development environment: Ubuntu 22.04

Development tool: Visual Studio Code

Development board: nrf5340dk_nrf5340_cpuapp_ns + nrf7002ek shield

Example refference path: ~/ncs/v2.7.0/nrf/samples/wifi/sta

We are using a custom board for our project, on it we have a nrf7002 wifi chip interfaced with nrf5340 SoC over SPI interface.

Till now our project code was based on ncs v2.7.0, with the sdk everything was working fine, including wifi. Note, Our project has https, wifi, and ble. We have enabled the ble co-existence.

Now, we have migrated our code from ncs v2.7.0 to ncs v3.0.0 and the wifi has stopped working with our project.

We are getting a wifi probe failure at bootup. The wifi configuration is same as the sample code in our project.

We have tested wifi sta sample code mentioned above. We don't get the probe failure with the sample code.

We need an assitance on what could be interfering with the wifi operation on our project firmware.

Attaching the error logs of wifi probe failure and of wifi sample code as well.

Thanks.

Hi, 

Try to create a sysbuild.conf to include SB_CONFIG_WIFI_NRF70=y and build with sysbuild. 

Regards,

 @Amanda Hsieh ,

The project already have a sysbuild.conf with SB_CONFIG_WIFI_NRF70=y and It is built with sysbuild.

Thanks.

The issue is duplicated [nRF5340 + nRF7002] nRF7002 wifi probe failure and wifi connection timeout issue, and my colleague is working on it. Please use that thread to continue the discussion. I will close this case.
