IWR6843ISK: question about calibdata configuration command in mmwave demo

moon sangik

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVE-DFP

calibdata configuration command is boot time RF calibration save/restore command .

There are many environmentally sensitive items that are calibrated by this command.

but there is no environment setting for this calibration in the "mmwave_sdk_user_guide"

Is it possible to run this command without setting a specify environment ?

(e.g., if you bring your hand to the radar sensor during calibration, it will not correct the wrong value)

second question

b1 APLL tuning (Ignore while restore)

In above , what means "ignore while restore"

thanks

Hello

Can you please clarify which Calibration command are you exactly referring to

The one in DFP API call for RF calibration

The one in OOB demo for angle, offset calibration.

Thank you,

Vaibhav

Hi Moon

In summary, below steps are required:

Save boot cal file in factory (interference free environment) and
In field, restore the saved cal file. Skip below boot calibrations using “AWR RFInit calib config” API before issuing “RFInit” API.

The below section is taken from the mmWave-DFP Release Notes:
