nRF7002DK doesn't appear in nRF Wi-Fi Provisioner

[robinvice]

Hello Nordic Engineers and community members,

I received an nRF7002-DK 1.0.2. (S/N: 1050757935), from Digi-Key today.

I've been following the YouTube video, "Getting Started with the nRF7002 DK" published January, 2023.

I have "nRF Connect for Desktop" v5.1.0 loaded and running on my Windows 11 workstation.

At 1:40 in the video, I add the hex file, and with the correct device selected, click on "Erase and Write."

1st question:

What hex file should I be loading?  I've tried:

1. wifi_scan_sample_ncs2.9.0.hex

2. merged_CPUNET.hex

3. merged.hex

4. provisioner-merged_domains.hex

5. nrf-wi-fi-provisioner.hex

Every one of these files resulted in a timeout when running "nRF Wi-Fi Provisioner" v1.2.0 on my Android Galaxy S24 Ultra.  I installed and opened "nRF Wi-Fi Provisioner", select "Provision over Wi-Fi", note the SSID name of "nrf-wifiprov", and tap the "Start" button next to "Connect". The app starts "Searching for devices..." until it times out and gives the message "No devices found. Make sure the device you want to connect to is turned on and ready to connect."

2nd Question:

Do you see what I'm doing wrong?

Thanks,

robin

Hi Robin,

Could you link the youtube video you're reffering to? Is it this one from https://www.nordicsemi.com/Products/Development-hardware/nrf7002-ek/getstarted#infotabs, i.e  https://www.youtube.com/watch?v=VRHPMQP6Ldk?

Youtube is unfortunately not as frequently updated w.r.t renewing the getting started materials, so sometimes you are better of by following the written getting started guides, such as these: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/gsg_guides/nrf7002_gs.html, or even the getting started guide from the WiFi fundamentals course at our academy pages: https://academy.nordicsemi.com/courses/wi-fi-fundamentals/.

W.r.t the build files, you can see that there are many various files generated, and they are described here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/config_and_build/output_build_files.html 

The merged.hex contains all the hex files for all images you've built, so in this case it should be that image you want to program.

Kind regards,
Andreas

Thanks for your response Andreas.

Here is the link. It's different from the one you referred to.

Great.  I'll look at the links you provided.

W.r.t the build files

I haven't built anything myself yet.  I found those hex files listed above on the NordicSemi website wrt the nRF7002-DK.

Loading the "provisioner-merged_domains.hex" allows me to provision the WiFi, but only through Bluetooth.

I'm just now starting out on this project, so I haven't loaded any sample project code, or written any code myself.

I will be using the following for development as soon as I get the hw working properly:
1. Windows 11 Pro for Workstations (10.0.26100) Windows x64
2. VS Code v1.99.2:
 a. nRF Connect for VS Code v2025.4.106
 b. nRF Connect for VS Code Extension Pack v2025.4.4
 c. nRF DeviceTree v2025.4.22
 d. nRF Config v2025.4.26
 e. nRF Terminal v2024.9.14

If you can point me to the sample project code from which the current provisioning hex files were generated, I'd appreciate it.

Thanks,
robin

Noted,

Then I understand your starting point better. Thank you.

You can find the sample here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/wifi/scan/README.html#wifi-scan-sample, i.e <ncs>/nrf/samples/wifi/scan in your local NCS path, from this step: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/gsg_guides/nrf7002_gs.html 

The precompiled merged.hex from the zip should result in a running application from the download page https://www.nordicsemi.com/Products/Development-hardware/nRF7002-DK/Download?lang=en#infotabs (atleast it did for me just now).

Let me know if this answers your questions or if you have any follow ups

Kind regards,
Andreas
