Is it possible to know the channel state information (CSI) from nRF chips?

Hi,

I'm wondering if CSI is available on nRF chips. It can be used for advanced sensing purpose. There have been tons of works on WiFi sensing through CSI. Is it by any chance stored in some registers or someplace in the RAM that users can access? Or is there a mode that it becomes accessible under?

Nothing like that in BLE low-power chips but as this is kind of statistical thing you can try to achieve it on higher layers of your SW stack (you just need to develop your own radio stack or modify some open source project like Zephyr).

Thanks for the answer!
