@vanvught Thanks for your report.
May I know why you are considering using the ESP32-S series chips to run ESP-AT? Have you explored alternative chips with better cost-performance, such as the ESP32-C series (ESP32-C3 or ESP32-C2)? Click ESP Product Selector for more details.

Current Status of ESP32-S2

The esp-at project doesn't support ESP32-S and ESP32-H series of chips on master, but we have restarted the support for ESP32-S2 chip with a low priority. If your product/project needs it in a hurry, please consider to speed up it by business, or uses a deprecated version.

Why isn't ESP32-S2 supported?

In fact, a few years ago, the ESP-AT project did support ESP32-S2. However, there were almost no real mass-produced products that required ESP-AT to run on ESP32-S2. As a result, the support priority for ESP32-S2 gradually decreased and was eventually removed.
