ESP32 wifi driver source code

[sherindeena]

Hi,

I am planning to use ESP32 S3. I want to know what level of exposure can I get into the wifi firmware? Is only API level exposure is provided or can I get the internal details, is it open source? I might want to get details like txsent interrupt time, tsf time, rxend interrupt time. My purpose of this is to achieve time sync between multiple wireless devices.

looks like the API esp_wifi_80211_tx is not exposed in the IDF. What are the typical txdelay of phy and mac when using this API for tx? Also is there any plan to support QoS data tx in the near future?
