AWR1843AOPEVM: sensorStart sometimes returns success and AWR1843AOPVM works with the online demo visualizer, and sometimes does not return and won't work.

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: AWR1843AOP,


I am using the AWR1843AOPEVM to test the AWR1843AOP sensor and sometimes when I try to use the online demo visualizer to test the sensor it will work wonderfully; however, sometimes sensorStart will not return success and the sensor will not output anything. Each time I use the evaluation module I set it up the same way: use the USB cable that came with the board, plug the board into my computer, launch the online demo visualizer, set up the serial ports & configuration values the same way, and send the configuration to the mmWave device.

Sometimes this works and I am able to see data from the sensor:

Other times it won't work and the log will stop at mmwDemo:/>sensorStart with no "Done" response from the sensor:

I have tried changing the calibration and sending calibrations from the demo files as specified in the ReadMe, but I haven't been able to find a fix. I am on Windows 10 and running the demo visualizer through Google Chrome.

Any help with this would be appreciated.

Thank you

  • Hi,

    Does this behavior happen after powering ON the evm?

    You should not change the calibration. You should try to load the configuration from PC.

    If this is performed...

    The only thing I can think that could cause this behavior is the USB cable. We have seen issues in the past caused by USB cables.

    Please also

  • Please also try to send the commands through a serial emulator such as tera term

    thank you
