Is it possible to perfrom CSI data extraction using nexmon tool happens in the following phones with the respective firmware patches given below and how?
Samsung Galaxy S22 Plus - 20_82_42_sta (r994653)
Google Pixel 7 and 7 Pro - 20_101_36_2 (r994653) and 20_101_57 (r1035009)
Google Pixel 8 - 24_671_6_9 (r1031525)

Our current extractor that can be found at https://github.com/seemoo-lab/nexmon_csi only support the Nexus 5 and Nexus 6P. In theory, this can be done on any device that features a BCM43-family Wi-Fi SoC.

So, can the same steps that are used to extract CSI data from Nexus 5 and Nexus 6P, be used to extract the CSI data from any device with BCM43-family Wi-Fi SoC.

[jlinktu]

At least similarly.
We will publish a remake of our extractor not too far in the future that supports also newer chipsets, i.a. those you are asking for.

[internrayiot]

How long will take to release the firmware to extract the CSI data using these devices?

[jlinktu]

There is no fixed date. We are done when we are done.

Hi I was looking for Samsung S20 firmware patches for Extraction of CSI data, for BCM4375b1 WiFi chipset.

Let me know if its available, since I could not find any patches.
