Device Info Packet
| 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 |
