Other Parts Discussed in Thread: IWR6843ISK
Hello everyone,

I don't quite understand what TLV is. what is the difference between numDetectedObj and numTLVs  ?
Is there a TLV structure diagram somewhere?

for the moment we suceed in parsing Header and  the object ( X,Y,Z and doppler) from recorded file in the mmwave demo but what comming next?
we use an IWR6843ISK whit SDK 3.5 and are unable to find a doccument like " mmw Demo Data Structure v0.1" pdf for SDK V1.0 which describe very well the data structure.

Thanks for your help.

    Hello

    What TLV means can be easily found on the web -->   Type–length–value - Wikipedia

    How each demo/lab  encodes their TLV is explained in the  User;'s guide.

    Please let u s know  which specific demo are you trying to understand the TLV for and could not spot the definition.

    Thank you

    Hello Vaibhav ,

    about the demo we use is "mmWave Demo Visualizer" wich is the out of the box demo for mmWave EVM (see attach the picture of the config tab of the demo).

    We already have the meaning of TLV but what i would know is when the EVM emit such mesure (for example, an object is detected when the EVM detect a peak in the radar signal).

    for the guides of uses I searched on everything I found (dyoxigen, resource explorer) and datasheet of all kinds find through the different topic e2e or on the TI page of the product the document "mmw Demo Data Structure v0.1" is very clear but it is not applicable for SDK 3.5 .

    thanks for your help and have a nice day.

    Hello,

    Please refer to the following resources to learn how the output TLVs for the OOB are structured:

    OOB Documentation:
    <MMWAVE_SDK_INSTALL_PATH>\packages\ti\demo\xwr68xx\mmw\docs\doxygen\html\index.html

    IWR6843ISK/ODS OOB User Guide:
    <MMWAVE_INDUSTRIAL_TOOLBOX_INSTALL_PATH>\labs\out_of_box_demo\68xx_mmwave_sdk_dsp\docs

    Hello,

    You asked for the documentation for the structure of data coming out of the radar device, that was provided. The role of this forum is for users to ask questions, not just state that they are stuck. If you have any specific questions that are tied to this thread with regards to the collateral I have provided then reply to this thread. If it is something not related then please start a new thread.

    Best regards,
