Original question:

IWR6843: How can I take data multiple times with mmWaveStudio CLI Tool?

IWR6843: Repeated soft reset will make the system unresponsive.

Part Number: IWR6843

I am doing continuous testing using deviceRestart, which you answered in the link below.
https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1062839/iwr6843-how-can-i-take-data-multiple-times-with-mmwavestudio-cli-tool/

For the first hour, the measurement and deviceRestart are repeating smoothly, but at some point, deviceRestart stops working.
Pressing the HardReset button on the IWR6843 restores it, but after a few measurements and deviceRestart, it stops working again.
Can you tell me what is causing this?

The board of the IWR6843 is hot, but the datasheet says "Operating junction temperature range" up to 105C, so I don't think there is a problem.

    Hi, 

    As mentioned in the other thread back to back data capture stop-start was not being verified with Studio CLI. Can you please let us know what is the target use case here?

    I am sorry, I did not understand the meaning you described.

    I am doing the following test.
    1. Run mmwave_studio_cli.exe
    2. Start capture
    3. quit execution
    4. repeat from number 1

    The mmwave_studio_cli.exe has been modified to execute deviceRestart at startup in addition to the link below.

    C:\ti\mmwave_platform_1_2_1\tools\studio_cli\gui\mmw_cli_tool\serial_comm\mmwave_comm.c

    		else
		{
			gUartComPortHandle = gMmwaveCommCfg.commHandle;

+			printf("DeviceRestart\n");
+			serialComm_Write(gUartComPortHandle, "deviceRestart \r\n");

			retVal = serialComm_CmdWrRd(gMmwaveCommCfg.commHandle, rlDevGlobalCfgArgs.ccsDebug

    If you repeat the test, deviceRestart will not work and you will have to press the Hard Reset button to recover.

    Hi, 

    I am not sure about the command that you are mentioning. below are the commands supported by ti\mmwave_studio_02_01_01_00\mmWaveStudio\ReferenceCode

    Can you please let us know if "deviceRestart" is a command that you have implemented? Please confirm. 

    The example using MATLAB to do the capture with CLI tools is attached here. Please refer to the same for back to back capture.

    Hi,

    "deviceRestart" is not implemented in mmwave_studio_cli.exe by default.
    I have implemented it by using the method described in the following URL.

    Hi, 

    If you look towards the end of the thread, it is recommended that it is not suitable for repeated resets. 

    "I was afraid of this only, as I mentioned that back to back data capture stop-start was not being verified with Studio CLI"
