Question:
In the profile.cfg file, I have set the frameCfg parameter as follows:
frameCfg 0 2 16 12000 5 1 0
When loopNum is set to 16, the mmWave radar can be started to collect data. However, when I set loopNum to 1, it fails to collect any data, using the following configuration:
frameCfg 0 2 1 12000 5 1 0
However, in Wmare Studio, I am able to set the "No of Chirp Loops" to 1, which corresponds to the loopNum in frameCfg. In Wmare Studio, I can successfully acquire data, but when using CLI commands controlled by a Python script, I am unable to collect data.
Is there a parameter that is not configured correctly? Or is it not supported to set loopNum to 1?
