I am using the Out of Box Demo with AWR6843AOP to detect static objects closer than 1 meter. I used the GUI to select and save config settings into a cfg file. I have not been able to run the live GUI demo, I just run the application in on my own hardware. I am receiving xyz data over UART, but have some questions:
- I am not receiving "Side Info" TLVs (#7) that include SNR values. I did earlier in development, but no longer. According to the header, I only get two TLVs: xyz (#1) and range profile (#2). My config file includes the line to enable side info:
guiMonitor -1 2 1 0 0 0 0 - How would you recommend I configure our radar for our setup? I want to detect objects at a max range of one meter. I am also separating the distance from radar to objects by over 5 cm. I have used the OOB Demo GUI to generate config files, but have not found detailed information on how to use each setting.
- My team has previously used the Vital Signs demo. I would like to mimic their settings as much as possible in the Out of Box demo. Previous conversations with TI support mentioned that we could mimic the chirp configuration settings of our vital signs app in the out of box demo. I tried copying these chirp configurations directly into my OOB cfg file, but then received no data. Which specific settings should be copied to best match our vital signs config?
Thank you for the help!
