Reachfar - RF-V03-SOS Protocol

This page describes the public protocol context for using the Reachfar RF-V03-SOS tracker with Plaspy. It focuses on how the tracker communicates with Plaspy servers in broad, non-sensitive terms so fleet managers and integrators understand connection expectations, transport options, and the role of the protocol in reporting location, events and telemetry.

Plaspy accepts data from supported trackers using shared connection settings. For Plaspy the server endpoint is d.plaspy.com and the server IP is 54.85.159.138 using port 8888. Devices can be configured to report over UDP or TCP to port 8888. Plaspy uses the same port for all supported devices and automatically detects the tracker protocol. Exact behavior can vary by firmware version, hardware revision, and manufacturer implementation, so consult the device maker for firmware specific details.

Protocol Overview​

The device communication protocol defines how the RF-V03-SOS reports position, status, events and alarms to a backend like Plaspy. In public terms the protocol ensures the tracker can identify itself, transmit telemetry that Plaspy can interpret, and support event reporting such as SOS, ignition state, and vibration alarms.

  • Enables periodic and event driven location updates from the device to Plaspy for live tracking and history.
  • Conveys device identity and status so Plaspy can associate incoming messages with the correct asset and telemetry fields.
  • Delivers event signals such as SOS presses, vibration alerts, and remote engine status that Plaspy surfaces as alerts and workflow triggers.
  • Supports buffered data upload after connectivity resumes so stored dead zone points reach Plaspy for history playback.
  • Operates over standard cellular transport so Plaspy can display location, alerts and telemetry without device specific app changes.

How Plaspy Detects the Protocol​

Plaspy is designed to accept connections from many trackers at a common endpoint and to detect the sending device protocol automatically. When an RF-V03-SOS is configured to report to the Plaspy endpoint the platform matches incoming sessions to the right protocol handler without requiring a manual selection in most setups.

  • Devices must be pointed to d.plaspy.com or the server IP 54.85.159.138 and use port 8888 to reach Plaspy.
  • Plaspy uses the same port for all devices which simplifies device configuration and onboarding.
  • Plaspy automatically detects the tracker protocol when the device reports to the endpoint so manual protocol selection is usually unnecessary.
  • Proper device configuration on the tracker side is required for automatic detection to succeed.
  • If behavior varies after setup, checking firmware version and device transport (UDP or TCP) is a practical first step.

Transport and Connection Context​

Connection context covers the network transports and endpoint settings the RF-V03-SOS can use to reach Plaspy. The device supports cellular reporting and stores data locally when coverage is lost, then uploads buffered points when connectivity returns.

  • The tracker may be configured to send data over UDP or TCP on port 8888 depending on device support and chosen settings.
  • Devices can point to the Plaspy domain d.plaspy.com or use the IP address 54.85.159.138 when configuring the server endpoint.
  • Plaspy uses the same listening port 8888 for all supported devices to simplify integration.
  • Choose UDP when light, low latency reporting is preferred and the device firmware supports it; choose TCP where reliable delivery and session persistence are important.
  • Ensure the cellular provider and any intermediate firewall allow outbound traffic to the Plaspy endpoint and port.

Protocol Compatibility Notes​

  • Firmware versions and hardware revisions can change how a device formats messages or which features are enabled; verify firmware on the tracker before deploying.
  • Manufacturer regional variants and radio module types can affect supported transports and available features, for example voice monitoring availability on certain variants.
  • Transport selection between UDP and TCP can be limited by device firmware or SIM provider network behavior.
  • Dead zone storage behavior and the maximum buffered point count depend on device firmware settings and storage configuration.
  • Because the RF-V03-SOS has been listed as out of production by the manufacturer, confirm availability and recommended alternatives with the maker.
  • Validate compatibility by comparing manufacturer release notes with Plaspy onboarding requirements for reliable integration.

Why Protocol Understanding Matters​

Understanding the communication protocol helps ensure correct configuration, faster troubleshooting, and predictable long term behavior when integrating the RF-V03-SOS with Plaspy. Clear expectations around transport, endpoints and event reporting reduce downtime and improve alert fidelity.

  • Helps confirm the device is pointed to the correct Plaspy endpoint and port so data arrives reliably.
  • Makes it easier to diagnose issues such as missing telemetry, incomplete event reporting, or delayed buffered uploads.
  • Supports informed choices about transport selection and firmware updates that affect functionality like voice monitoring or engine shutdown.
  • Assists operations teams in aligning device behavior with Plaspy alerting and reporting needs for safety and compliance.
  • Reduces surprises when migrating devices or updating fleet firmware by anticipating protocol-related changes.

Why Use Plaspy with This Protocol​

Pairing the RF-V03-SOS with Plaspy provides centralized visibility for fleets and asset owners who require reliable real time location, alerts and history playback. Plaspy receives the tracker telemetry and presents ignition status, SOS events, movement alarms and stored history in dashboards that support operational decision making and incident response.
