The ESP32 CSI Toolkit provides researchers access to Channel State Information (CSI) directly from the ESP32 microcontroller.
An ESP32 flashed with this toolkit can provide online CSI processing from any computer, smartphone or even standalone.
These features along with the ESP32's small size gives researchers the ability to perform tasks such as Wi-Fi Sensing and localization with CSI in new ways.
All without requiring complicated firmware hacks.
