0x01

0x08
0xA4
0x09
(channel 0,

0x22
0x13
0x17
0xDE
Bytes 2 and 3 indicate the transmission period, here 60 minutes (so a sample is measured every 30 minutes).
•
First sampling is 0x012C (3°C) / 0x2213 (8723 %RH)
•
Second is 0x08A4 (22.12°C) / 0x17DE (61.10 %RH)
NOTE
This example is valid for the product with a LoRaWAN module. In the case of Sigfox, the size of an uplink is 12Bytes and therefore this frame is divided in two.
Alert measurement frame
a high threshold being exceeded on channel 1 (virtual probe), the frame will be:
Octet
1
2
3
4
0x8D
(new generation alert frame)
0x58
(exceeding high threshold channel 1, temperature measurement)
0x02
0xC9
The sampling that triggered the higher threshold deals with 0x02C9 (7.13 °C)
