| 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 | |
| ICCID | 160 | 20 Bytes, Character string | 8991000903297069053F | |
| VID | 32 | 4 Bytes, Character string | TRAN | |
| CELLULAR_MODULE_FV NAME | 40 | 5 Bytes, Character string | TSPJT | |
| CELLULAR_MODULE_FV VERSION | 80 | 10 Bytes, Character string | XX.YY.ZZZZ | |
| CELLULAR_MODULE_FV BUILD NO | 40 | 5 Bytes, Character string | YYDDD | |
| MCU_APP_MODULE_FV NAME | 40 | 5 Bytes, Character string | TSPJT | |
| MCU_APP_MODULE_FV VERSION | 80 | 10 Bytes, Character string | XX.YY.ZZZZ | |
| MCU_APP_MODULE_FV BUILD NO | 40 | 5 Bytes, Character string | YYDDD | |
| MCU_BTL_MODULE_FV NAME | 40 | 5 Bytes, Character string | TSPJT | |
| MCU_BTL_MODULE_FV VERSION | 80 | 10 Bytes, Character string | XX.YY.ZZZZ | |
| MCU_BTL_MODULE_FV BUILD NO | 40 | 5 Bytes, Character string | YYDDD | |
| VN | 80 | 10 Bytes, Character string | KL07CP8490 | |
| HWINFO | 88 | 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 *) | |
