AWR1243: How to change chirp/profile of awr1243 without restart radar?

Part Number: AWR1243

We using awr1243 in cascading mode. We need to change microwave frequence,tx channel,time on the fly. But this process is not 100% success, sometime ok, sometime fail. Many times it produce error -7(Checksum value mismatched wrt to received data ),-8,(device failed to send response within time) .

We have set timeout to 1ms and using interrupt to process async event. We use mmWave Application Framework as software base archtecture.

Our process to update profile/chirp is that:

1. stop sensor;

2. re-set profile;

3. re-set chirp;

4. start sensor.

So how to change chirp/profile of awr1243 100% success ?

  • Hi,

    This should work normally. After the stop sensor command, you will need to wait for the ASYNC event from the device indicating successful sensor stop.

    Please ensure the master device is stopped first before stopping the slave devices.

    If you have more information on the sequences that generate the -7 or -8 error, do let us know and we can investigate. It helps if you can simplify the failing sequence a little.
