IWR6843: Advanced frame configuration with numOfBurstLoops other than 1

Part Number: IWR6843

Hello Community,

Is it possible to set numOfBurstLoops to 4 if  more burst loops we want get in one subframe. I have seen this value, numOfBurstLoops  = 1 in all advanced configuration file.

If not why ?

Please let me know your suggestion.

Thanks and Regards,

Neil

    Hello Neil, 

    The valid range for number of bursts in a subframe is 1 to 512. 

    Please refer to the mmWave Interface Control document or ICD (API - AWR_ADVANCED_FRAME_CONF_SB) for more specific details.

    I want to send 128 chirps first followed by 8 chirps in burst loop of 4. Please let me know if above configuration is correct for that. 

    Thanks and regards,

    Neil

    Hello Neil, 

    Please refer to the profile_advanced_subframe.cfg profile in the mmW demo profiles directory for example Advance frame usage. 

    Here is the path : mmwave_sdk_<version>\packages\ti\demo\xwr68xx\mmw\profiles\profile_advanced_subframe.cfg

    This will help you use the correct APIs for your chirp configuration. 

    Regards,

    Ishita
