GPRS Configuration
GPRS (General Packet Radio Service) communication is the main data transmission channel for Rinho devices. It enables sending position reports, status updates, and alerts to tracking servers via 2G/3G/4G networks.
What is it used for?
| Use case | Description |
|---|---|
| 📡 Report transmission | Send GPS positions and events to server |
| 🔄 Redundancy | MAIN and BACK channels for high availability |
| 🌍 Roaming | Switch carriers when crossing borders |
| 🔧 FOTA | Remote firmware updates |
| 📊 Telemetry | Send CANBUS data, sensors, etc. |
Available Commands
🌐IP - IP Destinations
Configuration of destination IP addresses (7 destinations)
→📶COPS - Carrier
Telephone carrier selection (roaming)
→🔌GPRSH - Disconnection
Forced socket disconnection
→🌍MC - Country Change
Triggers for country change (MCC)
→IP Destination Architecture
The system supports 7 IP destinations organized in channels to ensure redundancy:
| Channel | Destinations | Function | Priority |
|---|---|---|---|
| 🟢 MAIN | IP0, IP1, IP3 | Main reporting channel | High |
| 🟡 BACK | IP4, IP5, IP6 | Secondary simultaneous channel | Medium |
| 🔵 FOTA | IP2 | Reserved for OTA updates | System |
Automatic redundancy: If IP0 fails, the device tries IP1, then IP3. The BACK channel can simultaneously send to another server for backup.
How does redundancy work?
- Active MAIN channel: Device attempts to connect to IP0
- If IP0 fails: Automatically tries IP1, then IP3
- Parallel BACK channel: Can send copy to IP4/IP5/IP6 simultaneously
- Reconnection: When IP0 recovers, returns to main destination
