4.3. History frame

A history frame is sent every 12 hours, regardless of the frequency of data transmission.
Each history frame contains a reading of the last 12 measurements made. The measurements are organised from the most recent to the oldest.
The product records 1 value per hour except for the period of 12 hours.
To find the timestamping of measurements, the following formula must be applied:
Data 1 = history frame reception time - time tag
Data x = history frame reception time - time tag - x times the sample rate
Example:
FF 19 44 46 06 14 04 00 19 03 07 AD 02 00 00 00 00 2F 2F 01 13 00 02 08 07 00 B5 15 00 00 00 02 36 30 BF
