Coban - GPS306 Protocol

This page provides a public protocol context for using the Coban GPS306 with the Plaspy platform. It focuses on how the device communicates over the network to report location and status updates and explains the connection points that Plaspy accepts for ingesting data from this tracker. Technical specifics that depend on firmware or private manufacturer settings are intentionally omitted; this document centers on the publicly relevant communication details needed for integration with Plaspy.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device reports to the Plaspy endpoint. Exact protocol behavior for the GPS306 can vary with firmware version, hardware revision, or manufacturer implementation, and those differences may affect available commands, reporting intervals, and optional features such as SMS fallback or customized alarms.

Protocol Overview​

The GPS306 communicates location and telemetry using the device reporting capabilities provided by its GSM GPRS connection and GPS satellite positioning. In a Plaspy deployment the tracker sends its reports toward the Plaspy endpoint and Plaspy interprets the incoming messages so the data becomes usable in the platform for mapping, alerts, and historical playback.

  • The protocol defines how the tracker identifies itself and transmits GPS coordinates, time, and status information to the server.
  • It enables periodic and event driven position reports such as movement alerts, geo fence triggers, and over speed alarms.
  • Reporting can occur over the device internet connection so Plaspy receives live updates for monitoring and fleet oversight.
  • Protocol messages provide the fields necessary for Plaspy to map a device to an account and to display location on a map.
  • Manufacturer features like SMS reporting or specific alarm types are part of the device capability set and influence how often and in what form data reaches Plaspy.

How Plaspy Detects the Protocol​

Plaspy accepts incoming connections on a single, shared endpoint and port and uses that input to detect and handle the tracker protocol automatically. When a GPS306 is configured to report to Plaspy, users typically do not need to manually select a protocol inside Plaspy for the device to be recognized and parsed correctly.

  • Plaspy server domain for device reporting is d.plaspy.com and the server IP is 54.85.159.138.
  • Plaspy listens on port 8888 for device reports and uses that same port across all supported devices.
  • The platform automatically detects the tracker protocol when a properly configured device reports to the Plaspy endpoint.
  • If a device is sending to the Plaspy endpoint with correct credentials or identifiers, Plaspy will match incoming data to the device record and process the messages.
  • Proper device configuration to point to Plaspy is the common requirement; once connected, protocol selection inside Plaspy is usually unnecessary.

Transport and Connection Context​

Connection and transport choices are an important part of getting the GPS306 to deliver data reliably to Plaspy. The GPS306 can deliver reports over the internet connection provided by GSM GPRS, and in many deployments the transport is either UDP or TCP depending on device capability and configuration.

  • The GPS306 may be configured to use UDP or TCP on port 8888 to send reports to Plaspy.
  • Devices can be pointed at the Plaspy domain d.plaspy.com or directly to the IP 54.85.159.138 as the reporting endpoint.
  • All devices supported by Plaspy use the same port number 8888 for reporting, simplifying configuration and firewall rules.
  • Choice of UDP versus TCP can affect delivery characteristics such as retransmission and ordering but is selectable based on the device firmware and settings.
  • Ensure your network allows outbound traffic to the Plaspy endpoint on port 8888 for reliable reporting.

Protocol Compatibility Notes​

  • Firmware differences across GPS306 units can change available commands, reporting intervals, and optional fields in messages.
  • Hardware revisions or regional variants of the GPS306 may have small protocol differences; validate behavior when deploying at scale.
  • Selecting UDP or TCP transport is a device configuration setting and must match what the device firmware supports and what your network allows.
  • Some features described in marketing materials such as SMS fallback or advanced alarm options depend on configuration and SIM service availability.
  • Plaspy automatically detects the protocol when the device reports to its endpoint, but correct device identifiers and reporting configuration are required.
  • Always confirm compatibility and expected behavior against the manufacturer documentation for the specific firmware build installed on each device.

Why Protocol Understanding Matters​

Understanding the GPS306 communication protocol helps with successful setup, ongoing troubleshooting, and maintaining reliable device reporting within Plaspy. It provides clarity on what data to expect, how to configure transport, and how device side settings interact with the Plaspy platform.

  • It reduces time spent troubleshooting by making it easier to verify that reports are reaching d.plaspy.com or 54.85.159.138 on port 8888.
  • Knowing whether the device is configured for UDP or TCP helps diagnose delivery issues related to firewalls or network policies.
  • Awareness of firmware and hardware variations helps explain differences in available telemetry and alarm behavior between units.
  • Clear expectations about protocol behavior aid in mapping device messages to the right device record inside Plaspy.
  • It supports operational planning for fleet scale deployments where consistent reporting intervals and alarm handling are important.

Why Use Plaspy with This Protocol​

Using the Coban GPS306 together with Plaspy gives organizations a practical way to convert device reports into live location views, alerts, and historical data for operations and safety monitoring. The GPS306’s support for real time internet reporting, geo fencing, movement alarms, and over speed alerts pairs with Plaspy’s ingestion and display capabilities to provide visibility across vehicles and assets.
