Thank you Cesar.

I calculated the data payload size based on your suggested URL and "CSI2_16_Raw8_format.pdf" in https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/693093/awr1243-data-packet-packing-format-for-raw8-mode-8-bit.

Chirp profile information + The actual chirp number : 16 Bytes
Raw data : 512 * 3 (i.e. # of Rx) * 4 (i.e. I/Q) = 6144 Bytes / chirp
Chirp quality data : 8 Bytes

So the transferred data size (the data payload size) per chirp is 6168 Bytes in our case?

Hello Ken,

If they are using only 3Rx (not 4) , then the raw data calculation is correct. 

CP data is always 16 buts (if the user is enabling CP data, else its zero)

CQ data will depend on the which CQ user is enabling , CQ1, CQ2, how many slices they are enabling etc. Do you know if the customer is using CP and CQ data?

Hello Vivek,

It's my mistake. The number of Rx is 4. 

Let me check if the customer is using CP and CQ data.

Best regards,

Ken

Sure Ken.
