Hi ,

    We are trying to output a range doppler heatmap over UART with SDK 5.3, in mmwDemo_TransmitProcessedOutputTask() fuction:

    

    Below is part of the output data:

    

    The data doesn't look right. What changes should I make to get the correct data?

    Hello, 

    Please let me know exactly which demo software you are evaluating. SDK 5.3 contains 3 example demos, I believe you are running the "mmwave_demo" located at <MMWAVE_SDK5_INSTALL_DIR>/examples/mmw_demo/mmwave_demo, please confirm. 

    Also besides the changes in mmwDemo_TransmitProcessedOutputTask() which you have shown above, have you made any other modifications to the demo software?

    Please also provide more details about the configuration file you are sending to the device. Are you using a default .cfg file from the SDK? Have you made any modification to the .cfg file?

    Best Regards,

    Josh

    Hi Josh,

        I checked the configuration, found that the problem was "compRangeBiasAndRxChanPhase" error.

        Now the data looks right.  Thank you!
