There are certain conditions to which the RF-PHY must comply in order to be able to work for phase-based ranging, such as access to I / Q signals and a PLL that continues between TX / RX switching. Does the ESP32 complies with this or is this a limitation by the ESP32?
I think the hardware actually should have support for this (with a few restrictions, as in, if I recall correctly it only works for certain encodings), however the drivers do not have functionality to output the associated data yet. Also, the functionality is mostly untested so we don't know if it works in practice.
Hold that thought: something has been recently merged. Does https://esp-idf.readthedocs.io/en/latest/api-guides/wifi.html#wi-fi-channel-state-information do what you want?
