The uplink payload is encoded in hex
Firstly you need to divide the uplink payload into individual bytes (from left to right)
The 1st Byte is always Mode = it tells in what the device operates ()
The 2nd Byte is always Event = it tells what action triggered this message (e.g. short press, periodic report, breached the threshold, etc.) ()
The 3rd Byte - a. If the decimal value of 2nd Byte is lower than 128: i. The 3. Byte is appended payload mask () ii. The 4.–12. Bytes are the appended payload
b. If the decimal value of 2. Byte is higher than 127: i. The 3.–12. Bytes are Event specific payload
