Unit: min.
2.3.4 Historical Door Open/Close Event, FPORT=3
CPL01 stores sensor values and users can retrieve these history values via the
The historical payload includes one or multiplies entries and every entry has the same payload as Real-Time open/
close status.
• Each data entry is 11 bytes and has the same structure as
, to save airtime and
battery, CPL01 will send max bytes according to the current DR and Frequency bands.
For example, in the US915 band, the max payload for different DR is:
a) DR0: max is 11 bytes so one entry of data
b) DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
c) DR2: total payload includes 11 entries of data
d) DR3: total payload includes 22 entries of data.
If CPL01 doesn’t have any data in the polling time. It will uplink 11 bytes of 0
