Reachfar - RF-V20 Protocol
This page summarizes the public protocol context for using the Reachfar RF-V20 tracker with Plaspy. It is intended to help technical users and integrators understand how the device communicates in general terms with the Plaspy platform and what to check when configuring the tracker for remote reporting and monitoring.
The RF-V20 is a versatile quad band GPS tracker with features such as anti theft alarms, magnetic and vibration sensors, a long life battery, and multiple reporting options from website and mobile apps to SMS. 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 manufacturer implementation. Always verify device specific behavior against the manufacturer documentation when needed.
Protocol Overview
The RF-V20 uses standard mobile data transport to send location, status, and alarm information to a server endpoint. The device firmware packages telemetry and events and transmits them over the cellular data link so a server such as Plaspy can ingest and present the data for tracking and alerts.
- The protocol governs how the tracker formats and transmits location, time, and event data to a remote server.
- It enables the tracker to identify itself to the server so data can be associated with the correct device in Plaspy.
- Transport and server addressing work together with the protocol to deliver position updates, alarms, and status reports.
- Protocol messages inform the platform about alarms such as vibration, magnetic tamper, low battery, and SIM change events.
- The protocol behavior visible to users can change with firmware updates or optional configuration settings on the device.
How Plaspy Detects the Protocol
Plaspy receives device reports at a single shared endpoint and uses automatic detection to determine the tracker reporting protocol. In most cases, a correctly configured RF-V20 that points at the Plaspy endpoint will be recognized without requiring users to manually select a protocol inside the platform.
- Plaspy uses the same port for all supported devices and automatically detects the tracker protocol.
- If the RF-V20 is configured to report to the Plaspy endpoint, the platform will match incoming messages to the device record.
- Users typically do not need to choose a protocol in Plaspy when the device is sending to the configured endpoint.
- Proper device identification and a stable cellular connection are the most important factors for automatic detection.
Transport and Connection Context
The RF-V20 can use standard TCP or UDP transport over the cellular GPRS data channel to send telemetry to a server. For Plaspy, configure the device to report to the Plaspy server domain or IP on the shared port used by the platform.
- The device may be configured to use either UDP or TCP on port 8888 depending on device support and configuration.
- Plaspy accepts connections at the domain d.plaspy.com and the public server IP 54.85.159.138.
- All devices in Plaspy use the same port, simplifying device configuration across models.
- Choose transport (UDP or TCP) based on device settings and network reliability; both are supported by the platform.
- Ensure the device APN and GPRS settings are correct so the RF-V20 can establish an outbound data connection.
Protocol Compatibility Notes
- Manufacturer firmware versions can alter message frequency, field contents, or optional features that affect parsing and display.
- Hardware revisions or variants of the RF-V20 may expose different sensor configurations or optional input channels.
- Some installer or dealer firmware builds add custom commands or reporting options that differ from retail firmware.
- Transport selection between UDP and TCP affects delivery semantics but not the high level role of the protocol.
- Validate compatibility by checking the device is sending data to d.plaspy.com or 54.85.159.138 on port 8888 and that Plaspy recognizes the device.
- When in doubt, consult Reachfar documentation for firmware specific behavior before making integration decisions.
Why Protocol Understanding Matters
A practical understanding of the RF-V20 communication protocol helps streamline initial setup, reduces troubleshooting time, and improves long term reliability when the device is used with Plaspy.
- Knowing which transport and server settings the device uses helps confirm it can reach the Plaspy endpoint.
- Recognizing how the device reports alarms and status allows correct mapping of events in Plaspy dashboards and alerts.
- Awareness of firmware dependent behavior prepares integrators for variations in message content and frequency.
- Understanding identification fields and reporting intervals aids in debugging devices that do not appear in the platform.
- Clear protocol expectations make it easier to coordinate with the device supplier or manufacturer when unusual behavior occurs.
Why Use Plaspy with This Protocol
Using the Reachfar RF-V20 with Plaspy gives organizations a straightforward way to receive location, alarm, and status data from the tracker through a single managed endpoint. Plaspy is designed to ingest standard tracker reports, automatically detect protocols, and present telemetry and alerts so teams can monitor assets and respond to events.
