esp32-s2的usb otg和WiFi tof能否做更多的说明？

[tumuyan]

在开发文档里明确写了暂时还不支持usb otg和WiFi tof，但是我对此部分很感兴趣。能否帮忙多做一些说明？
S2的usb只支持host模式不能作为usb-hid设备被pc使用嘛？
WiFi tof百度搜索不到有效的信息，能否提供一些技术原理上的说明？
谢谢

The integrated USB OTG peripheral is not supported

Documentation not updated for ESP32-S2 in most places

Peripheral drivers and power saving modes are a work in progress

No hardware security features or cryptographic accelerator support

Time-of-Flight (TOF) measurements with normal Wi-Fi packets is not supported

Hi tumuyan,

The USB OTG peripheral on ESP32-S2 supports both Host & Device modes. Basic support for Device mode is already added: https://github.com/espressif/esp-idf/tr ... herals/usb however more practical device modes are not supported yet. Support for the ESP32-S2 becoming a USB HID device is planned. Thanks.
