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 (110 Bytes)
Time	32	80-111	UTC Timestamp	UTC time in seconds
Time Zone	8	112-119	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

CELLULAR_MODULE_FV VERSION	80	352-431	10 Bytes, Character string	XX.YY.ZZZZ
CELLULAR_MODULE_FV BUILD NO	40	432-471	5 Bytes, Character string	YYDDD
MCU_APP_MODULE_FV NAME	40	472-511	5 Bytes, Character string	TSPJT
MCU_APP_MODULE_FV VERSION	80	512-591	10 Bytes, Character string	XX.YY.ZZZZ
MCU_APP_MODULE_FV BUILD NO	40	592-631	5 Bytes, Character string	YYDDD
MCU_BTL_MODULE_FV NAME	40	632-671	5 Bytes, Character string	TSPJT
MCU_BTL_MODULE_FV VERSION	80	672-751	10 Bytes, Character string	XX.YY.ZZZZ
MCU_BTL_MODULE_FV BUILD NO	40	752-791	5 Bytes, Character string	YYDDD
VN	80	792-871	10 Bytes, Character string	KL07CP8490
HWINFO	88	872-959	11 Bytes, Character string	PCB-0220-AB
Tail(2 Bytes)
End Character	8	0–7	Starting character * (ASCII value 42)
CRC	8	8–15	8-bit XOR CRC of data starting from $ to * (excluding $ and *)
