Data code explanation
Data Format
Configurable parameters
The data frame contains 9 bytes, 2 bytes of frame head, 2 bytes of distance value (Dist_L and Dist_H), 2
bytes of signal strength (Strength_L and Strength_H), 2 bytes of temperature (Temp_L and Temp_H) and
1byte of checksum. All the data and commands are transmitted in hexadecimal format.
