➢
Each data entry is 11 bytes and has the same structure as Real-Time open/close status , to
save airtime and battery, LDS03A 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 LDS03A doesn’t have any data in the polling time. It will uplink 11 bytes of 0
