CSI demo question

BryanNiu — Wed, 22 Jul 2026 23:05:02 GMT

Hi,

This is Bryan form Quectel FAE team.

We are planning to prepare some CSI-related demos for the NXP trade show in September. Could you provide some assistance with demo examples?

For instance, I noticed you have examples similar to motion detection — I would like to know how to analyze and work with the CSI data captured on our board.

We have rw610 && rw612

Hi， @BryanNiu

For RW610 and RW612, both of them supports CSI.

We already have demo in the default SDK release: wifi_cli example.

The wifi_cli application is used to configure CSI generation and collection. The application is included in the SDK release. To generate CSI data, flash wi-fi_cli application onto the Wi-Fi device and run the following commands:

wlan-set-csi-param-header
wlan-set-csi-filter
wlan-csi-cfg
wlan-auto-null-tx

For the details, you can refer to:

AN14281: Channel State Information (CSI) on FreeRTOS | NXP Semiconductors

Please let me know whether still have any other concerns on this case, if no, please do not hesitate to mark my answer as a solution for this thread.

Best regards,

Christine.

Hi, @BryanNiu

By the way, to download our default SDK, you can just directly go to below link:

Select Board | MCUXpresso SDK Builder

Input and choose FRDM-RW612, then download the latest: SDK 26.06.00.

Best regards,

Christine.

Hi @Christine_Li

Thank you for the information. We have successfully run the basic wifi_cli example from the SDK.

We would like to go further and analyze CSI data to develop a demo. I came across the following repository for CSI motion detection on the RW61x — would this demo be compatible with our module?

https://github.com/nxp-appcodehub/dm-motion-detection-using-wifi-csi-on-rw61x

Or is there a similar demo you could recommend?

Thanks

Bryan

Hi, @BryanNiu

The demo you mentioned in the shared link is also designed for FRDM-RW612.

So, yes, it should work on FRDM-RW612.

If you are using a RW612 module, I think it should also work.

But from the SDK version, it is using SDK 25.09.00, a little older. Currently our latest SDK version is SDK 26.06.00.

You can have a try with our latest SDK 26.06.00, and according the the AN I provided to you to learn more info about CSI on RW612.

Please let me know whether still have any other concerns on this case.

Best regards,

Christine.
