Revision as of 11:08, 17 June 2025

Field	Size (bits)	Bit Range	Description	Breakdown
Header (10 Bytes)
Start byte	8	0–7	Starting character $ (ASCII value 36)
Data length	12	08–19	2-byte length of the data following the header
Number of data packets	5	20–24	Number of packets (0–32)	0–32
IMEI	50	25–74	Unique device identifier
Packet type	5	75–79	Type of packet	00 - Device Info
Data
Time	32		UTC Timestamp	UTC time in seconds
Time Zone	8		Timezone in quarter-hours (e.g., 22 = +5:30), quarter-hour increment means each unit represents 15 minutes. The value 22 represents 22 quarter hours. Ranges from -48 to 56, negative timezone to 2's complement representation	eg: 22 (+5:30) → 22×15=330 minutes → 330÷60=5.5 hours → 5 hours and 30 minutes
