IWR6843ISK: Long Range People Detection - How to Get Readable Data Over UART

Tool/software:

Hello,

I am working with the IWR6843ISK and have flashed the Long Range People Detection pre-built binary using UniFlash. I am using the Industrial Visualizer from:
radar_toolbox_2_30_00_12\tools\visualizers\Applications_Visualizer\Industrial_Visualizer

I have successfully sent the configuration file "6843_50m_2D.cfg" from:
radar_toolbox_2_30_00_12\source\ti\examples\Industrial_and_Personal_Electronics\Long_Range_People_Detection\chirp_configs

The visualizer shows some detections, so the setup seems to be working. However, my goal is to get the detection data over UART so that I can process it using another MCU.

What I Have Tried

• I connected the configuration UART to Tera Term (baud rate: 115200) and successfully sent the configuration commands.
• I connected the data UART to another Tera Term session. However, the output appears as junk characters, regardless of the baud rate I try.

Questions:

1. What is the correct baud rate and settings for receiving readable detection data over the data UART?
2. What is the expected format of the UART data? Is it binary, and does it require a specific parser?
3. Are there any additional steps or settings required to correctly receive and interpret the data?
4. Is there a recommended example code or tool for parsing and verifying the output from the data UART?

My goal is to detect a person/moving object and send the processed data over UART to another MCU. Any guidance on how to achieve this would be greatly appreciated.

Thank you!
