BOOSTXL-AOA: Time of Flight (ToF) measurement from Raw IQ data collected on AoA board

Part Number: BOOSTXL-AOA

Can we get Time of Flight (ToF) measurement from Raw IQ data collected on AoA board (once we can the timestep of each package)? Clément

As I have been able to run the demo code rtls_aoa_iq_with_rtls_util_export_into_csv.py in tutorial task 4 - get IQ data, and I modify the python code a bit to save down current timestep into .csv, and we got different package coming with different timestep.

So we can get the time difference between each package, if the TX is always transmitting, does the time difference mean the ToF? Or else, the TX is transmitting in a intermittent way, what is the period and duty cycle?

Best Regards.

Hi Jet,

I recommend looking at the SLA AoA course and the AoA chapter in the User's Guide. The timing behavior with AoA and the packets is discussed in the User's Guide. I recommend looking into that section and seeing if it answers you question. Can you verify if this is the case?

Sincerely,

Jan

Thanks, I did go over that, but the description does not match with the raw data I collected.

Best.

Hi,

To me, nothing here will allow you to perform Time Of Flight measurement.
