I can't find good explanation what "presence profile" is. I am attempting to run "presence_single_output" sample with X4M03 Radar Development Kit. The error I got is "ERROR: load_profile_failed". According to "Low Level Protocol Documentation" page 17, that value for presence (0x014d4ab8) should be valid. Module connector version is 1.6.2. So, my questions are what is presence profile and why would it fail to load on X4M03?
