Reachfar - RF-V43 Protocol

This page describes the public protocol context for using the Reachfar RF-V43 tracker with Plaspy. It focuses on how the device communicates at a high level, what role the tracker reporting protocol plays in sending location and alert data, and how those messages are delivered to the Plaspy platform. The RF-V43 is a compact 4G pet tracker that supports GPS, LBS, and WiFi positioning, plus features such as geofence alerts, a controllable LED, sport data, and battery status reporting.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device is properly configured to report to the Plaspy endpoint. Exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation, so this page focuses on public, non sensitive protocol context and practical integration guidance rather than firmware specific internals.

Protocol Overview​

At a high level the RF-V43 communication protocol defines how the tracker sends position updates, status reports, and alerts to a server and how remote commands or acknowledgements are optionally exchanged. For pet tracking the protocol's primary goals are reliable location reporting, timely geofence and low battery alerts, and support for any remote control features such as the LED or call function.

  • Enables periodic and event driven location and status reports from the RF-V43 to a server
  • Carries identification and status fields so Plaspy can associate messages with the correct device
  • Conveys geofence and low battery alerts that Plaspy can surface to users
  • Allows remote control or configuration commands when supported by the device and firmware
  • Supports multiple positioning sources including GPS, LBS, and WiFi to improve accuracy in different environments

How Plaspy Detects the Protocol​

Plaspy receives incoming device connections on a single shared endpoint and port and will automatically identify the tracker protocol when messages arrive from a properly configured device. In most cases a user does not need to manually select a protocol inside Plaspy as long as the tracker is pointed at the Plaspy endpoint.

  • Plaspy server endpoint can be reached at d.plaspy.com and its public IP address 54.85.159.138
  • Plaspy accepts device reports on port 8888 and all devices use the same port for reporting
  • The device may be configured to use either UDP or TCP on port 8888 depending on the RF-V43 firmware and settings
  • When the tracker sends its first messages to the Plaspy endpoint the platform uses those incoming messages to detect and apply the correct protocol handling automatically
  • For reliable detection ensure the device identification and reporting interval are enabled in the tracker configuration

Transport and Connection Context​

Connection setup for the RF-V43 is primarily determined by the device transport option and cellular configuration. The RF-V43 supports 4G connectivity and can submit its reporting data over TCP or UDP to the Plaspy endpoint. Transport selection may affect retry behavior and latency but does not change the fact that Plaspy uses the same port and automatic detection for all devices.

  • Devices may point to the hostname d.plaspy.com or the IP address 54.85.159.138 for reporting
  • Reporting uses port 8888 and the tracker may be configured to use either UDP or TCP on that port
  • All Plaspy supported devices share the same port 8888 for incoming reports
  • Cellular APN, signal quality, and carrier settings determine whether 4G connectivity can be used consistently
  • Firewall or NAT environments must allow outgoing TCP or UDP traffic to the Plaspy endpoint on port 8888

Protocol Compatibility Notes​

  • Firmware versions can change message fields, reporting behavior, and supported commands; always check the device firmware notes
  • Hardware revisions or SKU differences may alter available features such as WiFi scanning or specific alert types
  • Manufacturer configuration options like transport selection UDP versus TCP can affect how the device behaves on cellular networks
  • Some features such as sport data tracking or voice call support can be firmware dependent and may not be present on every unit
  • Plaspy automatically detects the incoming protocol but a misconfigured tracker endpoint will prevent detection
  • Validate device compatibility by comparing the tracker configuration against Plaspy connection requirements and manufacturer documentation

Why Protocol Understanding Matters​

Understanding the RF-V43 communication protocol helps ensure a smooth setup, reliable reporting, and easier troubleshooting when integrating the tracker with Plaspy. Knowing the general role of the protocol and the connection context shortens time to first fix and reduces uncertainty during deployments.

  • Helps determine whether a device is properly configured to report to d.plaspy.com or 54.85.159.138 on port 8888
  • Guides transport choices between UDP and TCP to match network conditions and device firmware
  • Makes it easier to interpret device behavior such as reporting intervals, geofence alerts, and battery notifications
  • Supports effective troubleshooting when a device is not visible in Plaspy by isolating network, transport, or firmware causes
  • Aids in planning firmware updates or feature rollouts by highlighting which functions are protocol dependent

Why Use Plaspy with This Protocol​

Using the Reachfar RF-V43 with Plaspy provides organizations and pet owners a practical way to centralize location, alerting, and device status information. The RF-V43 combines multiple positioning methods with weatherproof hardware and pet oriented features, while Plaspy offers a single endpoint and automatic protocol detection to simplify fleet or pet tracker onboarding.
