Each sample is coded on 2 bytes:
1 for presence: 8 unsigned bits. Represents occupancy rate (in %) during the concerned period.
•
Example: 50% = a presence detected half the time.
1 for brightness: 8 bits unsigned in %. Example: 50 => 50% brightness
•
Maximum number of samples per frame:
LoRaWAN 868: 24 samples

Presence state when sending the frame:
•
0: no presence detected
1: presence detected

Description
Frame code
Frame counter: 4
Bit1@0: LowBat not detected
A presence is currently detected
0x1E = 30 => a presence has been detected 30%
of the time during the concerned period (t-1 to t0)
0x32 = 50 => luminosity measured: 50%
0x00 = 0 => No presence detected during the
concerned period (t-2 to t-1)
0x20 = 32 => luminosity measured: 32%
Description
Frame code
Status byte
0: inactive alarm (end of presence)
1: active alarm (beginning of presence)
Measured luminosity when alarm has occurred
Description
Frame code
Frame counter: 4
Bit1@0: LowBat not detected
Presence detected
50 => luminosity at 50%
