Thanks for your reply. This wouldn't work anyway. When counting CPU clock cycles, the jitter in the timing before any code actually runs in response to a WiFi event/interrupt is huge (can be dozens or even hundreds of CPU cycles). I could live with that jitter, hypothising that since my WiFi task co...

Hi everyone, To implement Time-Of-Flight scenarios, I need to know the exact packet arrival time (accurate to ESP32 clock of 240MHz - 4 nanosecond) in the promiscuous mode callback. The current `rx_ctrl->timestamp` field received in the payload is not sufficient as it is precise only to the current ...
