Part Number: AWRL1432
Other Parts Discussed in Thread: IWRL1432

Tool/software:

Hi engineers,

        I want to ask if there are any ways to improve the cold start time(From the first power-on to the time it outputs target information) of the IWRL1432? Our demo board’s cold start time is approximately 500ms. Could you tell me what methods can be used to improve the cold start-up time.

BR

    Hi, there:

    What is the application you are working on?  Which demo you have been testing with?

    Best,

    Hi，

        We are working on liquid level meter，the demo project is level Sensing in the *\radar_toolbox_2_20_00_05\source\ti\examples\Level_Sensing\high_accuracy_low_power_sensors\src

    BR，

    Hi

    The Level sensing demo should send the first measurement around 50ms from the time the device is powered on. 

    From the time NRESET is de-asserted, application load and running the application takes around 40ms. For the application to run and send the data over UART it should take around 10ms. You can try by disabling the range data in guiMonitor CLI

    Hi,

         "he Level sensing demo should send the first measurement around 50ms from the time the device is powered on. " are you sure ？we tested the time is about 500ms,and I think the time by disabling the range data in guiMonitor CLI only few micro seconds.I believe the main time consumption is in the power-up RF startup and some configuration processes. Is there any way to reduce this time?

    Hi,

    Yes, the startup time will be around 50ms. How are you sending the configuration? 

    In your case, configuration needs to be hard coded, so that CLI commands are picked up directly from the binary

    Bootup will take around 40ms and for the first measurement it will be 10ms.  

    Regards
