At this time (December 2020) the Wi-Fi ToF, driver EDMA, USB Host & ULP coprocessor (state machine) features are still unsupported, and are planned for ESP-IDF v4.3.
---
ESP-IDF version 4.2, currently in development, will include support for the ESP32-S2 chip. This post lists the status of various ESP-IDF features on ESP32-S2.
For each feature, the status (Supported/Not supported) is given. An internal issue reference (such as "IDF-1234") is listed at the end of the feature description to help us keep this list up to date.
This list will be updated as the support for ESP32-S2 is being developed.
