IWR6843AOPEVM: Vital Signs With People Tracking

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843AOP

Hi,

I try to work Vital Signs with People Tracking demo.

When I asked a previous question, I received the following answers.

>Q: 1. How could I log both of heart rate and breath rate (ex. csv).

>A: 1. It is not possible to log directly through the visualizer but you can send the .cfg through tera term and log the UART output and you need to decode the TLV to extract the heart rate and breathing rate

So, I tried the steps below. I want get heat rate, breath rate and heart and breath wave data.

・STEP1: Connect to IWR6843AOP with TeraTerm

   [setting] speed: 115200

・STEP2: CLI Inputs (Same content as .conf)

Here, the content output to the terminal appears to be garbled.

Do you know what the cause is?

Also, is there a list of CLIs somewhere?

Best Regards,

  • Hi,

    You will have to store the data in teraterm as binary to collect the correct data.

    Another method that you can make use of is the save button on the Industrial Visualizer

    It will store the TLV received and you need to decode the vital signs TLV from the received TLVs

    1. Vital Signs TLV contains a header and Vital signs information 
    1. TLV header contains the TLV type and length information. TLV type is 0x410 and length is 136 (0x88) bytes 
    1. Vital signs information contains ID, Rangebin, Breathing deviation, Heart rate, Breathing rate, Heart rate circular buffer and Breath rate circular buffer

     

    Locate 0x410 in the saved log to locate the vital signs TLV and you can extract the 136 bytes in the TLV to decode heart rate and breath rate

  • Thank you for your response.

    I have some questions.

    Q1. Which Visualizer?  "radar_toolbox_1_30_00_05" ?

     I've been using Visualizer of the Visualizer of Industrial Toolbox (4.12.1) so far. 

    Q2. If Q1 is YES, where can I find the configuration file of Radar Toolbox (1.30.00.05) for the vital sign?

     I cannot find the folder for the vital sign at <RADAR_TOOLBOX_INSTALL_DIR>\src\ti\examples\

     So, currently, I use configuration file of Industrial Toolbox (4.12.1).

    Q3. Under the following conditions, there are errors as the pic.. Do you know what the cause is?

     ・Visualizer: Radar Toolbox (1.30.00.05)

     ・Configuration file: Industrial Toolbox (4.12.1)

     In the case of the Visualizer of Industrial Toolbox (4.12.1), there are no same problem.

    Q4. I wrote code to output UART information and the following output result is obtained, but is the output correct? I'm going to try the decoding process.

    Q5. I can use vital sign demo of Industrial Toolbox (4.12.1). But, when I restart the visualizer, the following error occurs. Do I have to press the NRST switch every time I start it?

    Best Regards,

  • Hi,

    You need to use the visualizer in the radar tool box. radar_toolbox_1_30_00_05

    1. You can use the below link to install radar tool box. 

    https://dev.ti.com/tirex/explore/node?a=1AslXXD__1.00.01.07&node=A__AGvTEJkh-csqqwXnVhDbTQ__radar_toolbox__1AslXXD__LATEST

    2.Have you correctly used the vital_signs_tracking_6843AOP_demo.bin? This is the binary applicable for IWR6843AOP. Also, the correct cfg would be vital_signs_AOP_2m or vital_signs_AOP_6m. This is typically the case if any of the above is a mismatch

    3. Please use the Save UART button in the visualzer. That would store the recieved TLV

    4. Please use the demo in the radar tool box. The visualizer in the industrial tool box is not supported

    Regards

  • Thank you very much for your support.

    I was able to decode against the saved file.

    Let me ask you three more questions.

    1. In Vital Signs With People Tracking, what is the difference between what is provided in Radar Toolbox and Industrial Toolbox?

    2. The installation position of the sensor is described as follows, but is it difficult to measure from an oblique top? For example, a sensor is installed at a height of about 2.0 m to acquire data on a sitting person. Or will it be feasible in the settings?

        > The EVM needs to be mounted at a height of ~1 - 1.5 to face a seated person

    3. When executing with the correct file (.bin and .cfg), the following error occurs, what is the cause?

    Best Regards,

  • Hello, 

    Much of the mmWave radar support team is out of the office right now. Responses may be delayed until the beginning of January. Your patience is appreciated.

    Best Regards,

  • Hi

    1.Earlier, Radar applications were divided into Automotive toolbox and Industrial Toolbox. Now, it is offered as Radar Toolbox

    Radar toolbox will contain the latest updates and any bug fixes from the earlier Industrial tool box. Please use Radar tool box as support for the components in it would be easier

    2.Sensor should be mounted right in front of the person and should point to the chest area of the person. Please reduce the height of the sensor in the configuration as well as in the setup. It might be incorrectly mentioned in the reference cfg. Sensor should be right in front of the sitting person and should be at the same height as the chest of the person

    3.The error indicates that visualizer is unable to extract some of the fields in the UART data sent by the sensor. Statistics data is not decoded by the visualizer. It should affect any of functionality. You will be able to see Vital signs related data still displayed in the visualizer

    Regards

  • Thank you very much for your support.

    Regarding question 3,
    it is stated that "It should affect any of functionality.", but,
    I think that "It should not affect any of functionality." from the preceding and following sentences.

    Which is correct?

  • Sorry, It is a typo.  "It should not affect any of functionality."

    Regards
