ArkNav - RV-8 Protocol
This page describes the public protocol context for using the ArkNav RV-8 GPS Fleet Tracker with Plaspy. It focuses on how the device communicates with the Plaspy platform in general terms, how the shared connection settings are used, and what integration considerations matter for reliable telemetry and position reporting. The guidance here is intended to help integrators and fleet managers understand connectivity and compatibility without exposing private implementation details.
Plaspy accepts connections from supported trackers using a shared endpoint and port and automatically detects the tracker protocol when the device is correctly pointed at the Plaspy endpoint. Exact protocol behavior, packet contents, and firmware features can vary by RV-8 firmware version, hardware revision, and manufacturer configuration, so device settings and capabilities should be validated against ArkNav documentation and the deployed firmware release.
Protocol Overview
The RV-8 tracker uses its onboard firmware to collect GNSS and vehicle telemetry, then transmit that data to a remote server for processing and visualization. The communication protocol defines how the tracker identifies itself, how position and event data are formatted and sent, and how optional encrypted channels are used to protect telemetry in transit.
- Enables periodic and event driven reporting of GNSS fixes, vehicle telemetry and alarm events to Plaspy for mapping and alerts.
- Provides device identification and session information so Plaspy can associate incoming data with the correct device record.
- Supports hybrid location reporting that combines uBlox GNSS fixes with cell based fallback to improve coverage in weak signal areas.
- Can use encrypted transport options available on the device such as AES256 and SSL256 to enhance data privacy.
- Carries diagnostic and peripheral data such as OBDII, CANBus, and accessory sensor telemetry alongside position updates.
- Allows for heartbeat or keepalive messages so the platform can monitor device online status.
How Plaspy Detects the Protocol
Plaspy is designed to accept connections from many different tracker models at a single, shared service endpoint and automatically determine which protocol a device is using when valid data arrives. This reduces setup steps inside the platform and streamlines device onboarding for mixed fleets.
- Devices should be configured to report to the Plaspy server domain d.plaspy.com or to the Plaspy server IP 54.85.159.138.
- Plaspy listens on port 8888 for incoming tracker connections and uses that same port for all supported devices.
- Plaspy automatically detects the tracker protocol when the device sends data to the Plaspy endpoint, so manual protocol selection in the platform is not typically required.
- Proper device identification and correct server settings are the usual prerequisites for automatic detection and successful data mapping.
- If a device is not detected automatically, common troubleshooting steps include verifying APN and SIM connectivity, confirming server address and transport type, and checking firmware compatibility.
Transport and Connection Context
The RV-8 can be configured to use different transport modes depending on device firmware and deployment preferences. For connectivity with Plaspy, the key connection parameters are the server host and the shared port used by the platform.
- The device may be configured to use UDP or TCP on port 8888 depending on device support and administrator choice.
- Devices may point to the Plaspy server domain d.plaspy.com or to the numeric server address 54.85.159.138.
- Plaspy uses the same port 8888 for all devices to simplify configuration and firewall rules for integrators.
- If encrypted communications are required, configure the device to use the device supported encryption options and verify compatibility with Plaspy during testing.
- Ensure the device APN and cellular settings allow outbound connections to the Plaspy endpoint and that any carrier firewalls permit the selected transport.
Protocol Compatibility Notes
- Firmware revisions can change protocol details and available features; always confirm behavior against the device firmware release notes.
- Hardware revisions and optional accessory modules may add or modify telemetry fields that the platform receives and displays.
- Transport selection between UDP and TCP can affect delivery characteristics; choose based on network reliability and application needs.
- Manufacturer side settings or regional device variants may alter default server settings or encryption capabilities.
- Verify that the device APN, SIM configuration and power wiring match ArkNav recommendations to avoid intermittent connectivity.
- Use staging or test devices to validate Plaspy integration before large scale deployment.
Why Protocol Understanding Matters
A practical understanding of the tracker protocol improves setup success, reduces troubleshooting time, and helps ensure reliable long term operation in Plaspy. Knowing what the device sends and how it connects lets integrators align network, security, and platform expectations for production use.
- Ensures the device is pointed at the correct Plaspy endpoint and port to allow automatic protocol detection.
- Helps diagnose connectivity issues such as wrong transport type, incorrect server address, or SIM and APN misconfiguration.
- Clarifies which telemetry fields are available from the device so Plaspy dashboards and alerts can be configured properly.
- Informs decisions about encryption and security settings to meet organizational policies.
- Prepares teams for firmware upgrade impacts on reporting behavior and available features.
Why Use Plaspy with This Protocol
