Coban - GPS-109 Protocol

This page describes the public protocol context for using the Coban GPS-109 tracker with Plaspy. It focuses on how the tracker communicates with the Plaspy platform at a high level, what connection settings are used, and practical compatibility considerations without exposing private or sensitive implementation details.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, while exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation. The GPS-109 itself operates on GSM GPRS and GPS satellites, supports SMS configuration, and provides location and alarm reporting which affect how it should be configured to report to Plaspy.

Protocol Overview​

The tracker reporting protocol defines how the GPS-109 sends location, status, and alarm data to a remote server and how it receives configuration commands or acknowledgements. For integration with Plaspy, think of the protocol as the language the tracker uses to make its data usable by the platform and by downstream reporting tools.

  • Enables the GPS-109 to report location, speed, and movement or alarm events to a remote server for processing.
  • Carries device identity and status information so Plaspy can associate incoming messages with a specific tracker.
  • Supports multiple reporting methods including GPRS data sessions and SMS based configuration or fallbacks.
  • Allows the platform to receive periodic updates and alerts that are translated into usable telemetry for monitoring and history.
  • Facilitates remote configuration when the tracker and the server are both correctly addressed and reachable.

How Plaspy Detects the Protocol​

Plaspy receives tracker reports on a common endpoint and port and automatically detects the tracker protocol from incoming data patterns and device behavior. This means users generally do not need to select a protocol manually inside Plaspy as long as the device is configured to report to the Plaspy endpoint.

  • Plaspy servers accept tracker connections at the domain d.plaspy.com and the public IP 54.85.159.138.
  • The universal Plaspy port for all supported trackers is 8888 and Plaspy uses the same port for every device.
  • Devices may be configured to use either UDP or TCP to send data to Plaspy on port 8888 depending on device capabilities.
  • When a properly configured GPS-109 reports to the Plaspy endpoint, Plaspy will detect the tracker protocol automatically and associate the device with your account.
  • Because detection is automatic, correct server addressing on the tracker side is typically the key step for successful integration.

Transport and Connection Context​

Connection context is important when configuring the GPS-109 to report to Plaspy. The tracker can use the cellular network for GPRS data sessions to reach Plaspy, or it can use SMS for direct commands and fallbacks. Understanding the supported transport modes will help you choose the right settings for reliability and battery life.

  • The GPS-109 may be configured to use UDP or TCP on port 8888 when reporting to Plaspy.
  • Devices can be pointed to the Plaspy domain d.plaspy.com or directly to the IP address 54.85.159.138.
  • All devices in Plaspy use the same port which simplifies configuration lists and firewall rules.
  • Use TCP when you need connection oriented delivery and use UDP when the device expects lower overhead reporting, subject to device firmware support.
  • SMS remains a possible configuration and control channel for many Coban trackers and can be used for initial setup or emergency commands if data is unavailable.

Protocol Compatibility Notes​

  • Firmware versions can change message behavior and supported features, so the same model can behave differently across firmware revisions.
  • Hardware revisions and optional modules may add or remove capabilities that affect protocol interactions and available telemetry.
  • Manufacturer side settings and regional firmware builds can produce protocol variations between otherwise identical model numbers.
  • The choice of transport mode TCP vs UDP may affect delivery reliability and how the device establishes sessions to the server.
  • Ensure the device is configured to report to d.plaspy.com or 54.85.159.138 on port 8888 to allow Plaspy to receive messages.
  • Validate compatibility by comparing the device configuration options and manufacturer documentation with Plaspy connection requirements.

Why Protocol Understanding Matters​

A practical understanding of the communication protocol helps ensure successful setup and reliable operation when pairing the GPS-109 with Plaspy. Knowing what the device sends and how it reaches the server reduces setup time and simplifies troubleshooting.

  • Expedites initial configuration by focusing on correct server address and transport settings.
  • Helps diagnose reporting gaps by revealing whether an issue is network, transport, or firmware related.
  • Improves alarm and geofence reliability by aligning device reporting intervals and event reporting behavior with platform expectations.
  • Enables efficient battery and data usage planning by choosing appropriate reporting intervals and transport modes.
  • Assists in long term maintenance when firmware updates change reporting behavior or available features.

Why Use Plaspy with This Protocol​

Using the Coban GPS-109 with Plaspy gives organizations an efficient way to convert the tracker s raw location and alarm reports into continuous visibility and operational insight. Plaspy s automatic protocol detection and unified port approach reduce configuration complexity and let teams focus on monitoring, alerts, and analytics rather than device connectivity details.

If you need centralized tracking, historical playback, or rule based alerts from Coban GPS-109 devices, configuring the tracker to report to the Plaspy endpoint is a practical first step.
