ST67W: WiFi CSI - Channel State Information - for sensing ?

Andrew Neil · ‎2026-06-02

Use of WiFi CSI for sensing seems to be getting quite some attention lately; eg,

So: do the ST67W provide access to CSI ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hello Neil,

You are right. Channel State Information (CSI) is getting some attention.
Our ST67W HW includes CSI data and we plan to make them available through API.
We'll keep you updated when the feature will be released (no commitment date for the time being).

Br,
Benoit
