Custom PCB nRF7002 on 5340

[chromedev]

We have a new custom PCB that has been extensively reviewed that we believe is wire correctly.

The developer on the board uses Segger and wants to do some basic testing outside of installing nrfConnect and using Zephyr.  I saw a low level access to the 7002 in a library but don't see much documentation. 

Can anyone advise a simple test to prove that the 5340 and the 7002 are able to communicate on a new PCB?  

We do have zephyr running on our PCB, but looking for something lower level to do basic testing.

thanks in advance.

Hi,

 

What is the pin connection(s) between the nRF7002 and the nRF5340?

 

If you use the same pin out as the nRF7002-DK (which has the nRF5340 + nRF7002), you can re-use this board to run wifi samples.

Can anyone advise a simple test to prove that the 5340 and the 7002 are able to communicate on a new PCB?  

The very first sample that you should run is the wifi/radio_test sample, and run step 1 from this guideline document:

MAC address can be set on a firmware level (see https://github.com/nrfconnect/sdk-nrf/blob/v2.5.1-rc1/samples/wifi/scan/src/main.c#L322-L356), or you can set it in the nRF7002 OTP area if wanted. 

 

Kind regards,

Håkon
