Thank you for your reply, I have been reading the code and there are some things that I am not sure to understand.
- The Espargos code uses rxstart_time_cyc & rxstart_time_cyc_dec for the ns timestamp calculation
- Both values are not documented in the Espressif code and just marked as /*< reserved */
- The timestamp parameter is documented but it is in "microseconds"
Is there anywhere I can find more documentation on the "rxstart_time_cyc" and "rxstart_time_cyc_dec" fields? Are these cycle counters from the wifi chip?
