5.4 Warning for Plots and Frame Rate

The following are some guidelines for selecting the plots and frame rate:

  • If heatmap is selected, reduce the frame rate to less than 5 fps. (If this suggestion is not followed, then the target mmWave device intentionally halts and the user must reboot the device).
  • If heatmap is not selected but all other plots are selected, then depending on the scene parameters selected, the GUI performance can be sluggish and the user should ideally select 10 fps as the frame rate.

Alternatively, user can select higher baud rates for DATA_port in the "Serial port" dialog using custom values when using mmW demo from mmWave SDK 3.4 or later. Recommended custom values are 1834000 or 3125000.
