There are some common Aware Status values that are presented by sensors during communication. Ultimately to understand these values, you will need to interpret the value by breaking down the Aware and STS bits as per this article. Though the information below can help you quickly understand some common Aware Status values below.
0 = Non Aware
1 = Non Aware, sensor start up
2 = Aware
3 = Aware, sensor start up
16 = Non Aware, profile specific (example, temp is using default calibration and is not Aware)
17 = Non Aware, profile specific (example, temp is using default calibration and is not Aware), sensor start up
18 = Aware, profile specific (example, temp is using default calibration and is Aware)
19 = Aware, profile specific (example, temp is using default calibration and is Aware), sensor start up
