Reachfar - RF-V40 Protocol

This page provides a public protocol context for using the Reachfar RF-V40 tracker with the Plaspy platform. It explains how the RF-V40 communicates in general terms with Plaspy, what connection settings are used, and what to check when configuring the device for reliable reporting and monitoring. The content here focuses on communication roles and compatibility considerations rather than manufacturer private internals.

The RF-V40 is a compact 3G pet tracker with GPS, AGPS, LBS and WiFi-assisted location capabilities and IP66 protection. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, but exact protocol behavior can vary by firmware version, hardware revision, and the manufacturer implementation. Use this overview to understand how the tracker and Plaspy interact and to guide setup or troubleshooting, and consult the official manufacturer documentation for device specific details.

Protocol Overview​

The communication protocol for the RF-V40 governs how the tracker reports position, status, and events to a remote server like Plaspy. At a high level the protocol ensures the device can identify itself, deliver location fixes and telemetry, and carry simple commands or status requests between the tracker and the platform.

  • Enables periodic and on demand reporting of GPS, AGPS, LBS and WiFi assisted location to Plaspy.
  • Provides telemetry reporting such as battery level, connectivity state, and SIM change notices for event handling.
  • Carries identifiers the platform uses to associate incoming messages with an account and a specific device.
  • Supports status and keepalive messages that help Plaspy maintain an accurate online view of the tracker.
  • Allows the device to be polled or to send alerts that trigger notifications and trace recording within Plaspy.

How Plaspy Detects the Protocol​

Plaspy accepts device reports at a single shared endpoint and automatically detects the tracker protocol so users normally do not need to choose a protocol manually inside the platform. Proper device configuration to report to Plaspy is typically the only step required for the RF-V40 to be recognized and to begin sending location and status updates.

  • Plaspy server domain is d.plaspy.com and Plaspy server IP is 54.85.159.138 for device reporting.
  • The port is 8888 and Plaspy uses the same port for all supported devices.
  • The device may be configured using UDP or TCP on port 8888 depending on device support and configuration.
  • Plaspy automatically detects the tracker protocol when the RF-V40 is correctly pointed to the Plaspy endpoint.
  • When configured to report to Plaspy, the RF-V40’s position and telemetry flow into Plaspy dashboards, alerts, and history views without manual protocol selection.

Transport and Connection Context​

Connection context covers how the RF-V40 reaches Plaspy over the cellular network and what network settings to use on the device. The RF-V40 sends data over cellular data channels and may use multiple transport options depending on firmware and configuration choices.

  • The device may use either UDP or TCP transport to communicate with Plaspy.
  • Configure the tracker to report to d.plaspy.com or to 54.85.159.138 as the destination host.
  • The device should be set to use port 8888 which is the shared port Plaspy uses for all devices.
  • Choose UDP or TCP on the device according to what the specific RF-V40 firmware supports and any operator network considerations.
  • Verify APN and SIM settings on the RF-V40 so the tracker can establish a data session before attempting to reach Plaspy.

Protocol Compatibility Notes​

  • Firmware differences can change the behavior of message timing, supported transports, and available telemetry fields.
  • Hardware revisions of the RF-V40 may introduce small variations in radio bands or GNSS performance that affect reporting reliability.
  • Manufacturer-side configuration options such as reporting intervals, on demand commands, and SMS fallbacks can alter how often the device contacts Plaspy.
  • Transport selection (UDP vs TCP) is device dependent; confirm which transport modes are supported by the RF-V40 firmware edition you have.
  • SIM configuration and APN settings must be correct for the device to open a data session to Plaspy.
  • Always validate compatibility and configuration steps against the latest Reachfar user manual and release notes.

Why Protocol Understanding Matters​

Understanding the RF-V40 communication protocol and connection context helps ensure correct initial setup, quicker troubleshooting, and long term reliability when the tracker is used with Plaspy. Knowing what the tracker is expected to send and how it reaches the platform reduces configuration errors and shortens time to reliable monitoring.

  • Ensures the device is pointed to the correct Plaspy endpoints and transport mode for successful reporting.
  • Helps diagnose common issues such as missing telemetry, delayed updates, or incorrect device identification in Plaspy.
  • Guides selection of reporting intervals and power settings to balance battery life with location freshness.
  • Clarifies when behavior differences stem from firmware or hardware rather than Plaspy configuration.
  • Supports coordinated testing during rollout of multiple devices to a single Plaspy account.

Why Use Plaspy with This Protocol​

Using the Reachfar RF-V40 with Plaspy provides a centralized way to manage pet tracking telemetry, alerts, and history alongside other devices. Plaspy’s ability to receive the RF-V40’s GPS, AGPS, LBS and WiFi assisted location updates, then present them in dashboards and mobile interfaces, makes it practical for owners and small operations to maintain situational awareness and respond to events like low battery and SIM changes.

Plaspy accepts reports at d.plaspy.com or 54.85.159.138 on port 8888, and the platform uses the same port for all supported devices while automatically detecting the tracker protocol.
