Part Number: AWR1642BOOST
Other Parts Discussed in Thread: DCA1000EVM

I want to tranismit  a continuous wave, but there is not much document? So I want to ensure the device can be changed to CW mode from FMCW mode. If it can, how to change?

    Yes this device supports CW mode.

    You can use either mmwave studio or mmwavelink test application to enable this feature.

    .

    Look for rlSetContModeConfig and rlEnableContMode APIs

    .

    Thanks for your response, but I cann't find rlSetContModeConfig and rlEnableContMode APIs on mmwave studio, there are so many buttons, can you upload a picture?

    Sincerely, 

    Mayo.

    Hi,

    In mmwave studio you can go to ContStream tab for continuous streaming configuration.

    Here is a screenshot for the same - 

    In the StreamConfig area set the values of the parameters and click set(1). Then set the StreamEnable Enable(2). Now you will be able to transmit a continuous wave.

    Otherwise in mmwavelink test application go to main_mss.c and search for gLinkContModeTest. This global variable is set false by default, to use the device in CW mode you need to set this as true.

    Thanks,

    Hi,

    Thank you very much.I followed your answer, when I click capture(4) and then discature, DCA1000evm continuously cllects data( the light keeps flashing), I cann't stop it. What's the reason?  Is there any error?

    And I want to konw what button set(3) means? Is this preprocessing of received data?

    Sincerely，

    Mayo

    Hi,

    Query 1:

    It seems with the current version of the studio it is an small issue, let me check on that with my team and get back to you by tomorrow.

    Quick Fix1: In mmwave_studio_02_01_01_00\mmWaveStudio\PostProc  you will find DCA1000EVM_CLI_Control.exe. Open a command prompt and run the command "DCA1000EVM_CLI_Control.exe stop_record cf.json". 

    Quick Fix2: If above fix doesn't work then you can try resetting the DCA1000EVM itself. That will stop the capturing and save the captured data. 

    Query 2:

    This set(3) button is applicable for Basic Configuration for Analysis block. It helps you configure the parameters for analysis tool. 

    [P.S: Whenever you click a button, it calls a specific function and you can check that in the output window. Now in the Lua shell, type "help ar1.<function_name>". That will display the function details. You can check details of any function here.] 

    Thanks,
    Anirban

    Hi,

    Have your team found the problem? I still haven't found a solution to first question.

    Thanks,

    Hi Mayo,

    Yeah, it is a small issue with the mmwave studio version 02.01.01.00. For now, please use the suggested quick fix for stopping the device from capturing data infinitely.

    Thanks,
