ArkNav - AT-5000 Protocol

This page describes the public protocol context for using the ArkNav AT-5000 with Plaspy. It focuses on how the tracker communicates with the Plaspy platform at a high level and what to expect when configuring the device to report location and status to Plaspy. The goal is to provide clear, non-sensitive protocol guidance to assist setup and troubleshooting while encouraging verification against manufacturer resources.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol once the device is reporting to the Plaspy endpoint. Exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation, so configuration and message details may differ across firmware builds of the AT-5000.

Protocol Overview​

The device protocol defines how the AT-5000 formats and sends location, status, and event information to a remote server so Plaspy can ingest, decode, and display the data. This documentation keeps protocol discussion general and implementation neutral while explaining the role the protocol plays in reliable reporting to the Plaspy service.

  • Enables the AT-5000 to package position, movement, and status data for transmission to a remote server.
  • Lets the tracker identify itself so Plaspy can associate incoming data with the correct device record.
  • Handles periodic reporting and event driven messages such as movement, timer wakeups, and low battery alerts.
  • Determines whether messages are sent over UDP or TCP depending on device settings and network conditions.
  • Supports auxiliary features reported by the device such as AGPS fixes, cell based location, and power management states.

How Plaspy Detects the Protocol​

Plaspy accepts incoming connections on a shared endpoint and automatically detects the tracker protocol for devices that report to that endpoint. In most cases a correctly configured AT-5000 will not require manual protocol selection in Plaspy; the platform matches incoming data patterns to the appropriate device parser and routing logic.

  • Plaspy listens on a single standardized server endpoint to simplify device configuration.
  • When an AT-5000 reports to the Plaspy endpoint, the platform inspects the incoming data and associates it with the device record.
  • Users typically configure the device to report to the Plaspy server and let automatic detection handle protocol mapping.
  • Automatic detection reduces the need for manual protocol selection inside the Plaspy interface.
  • Ensure the device identification settings (IMEI or device ID) are correctly set on the AT-5000 so Plaspy can link messages to the right device.

Transport and Connection Context​

The AT-5000 can send data over the network using commonly supported transport methods. For Plaspy integration the connection and transport choices are standardized to simplify device setup and to support a broad range of cellular environments.

  • Devices may be configured to connect to the Plaspy server domain d.plaspy.com or directly to the server IP 54.85.159.138.
  • Plaspy accepts both UDP and TCP connections on port 8888 depending on device support and configuration.
  • All devices in Plaspy use the same port which simplifies provisioning and firewall configuration.
  • Choose UDP when lower overhead and simpler retransmission behavior is preferred, or TCP when session reliability is required, subject to AT-5000 firmware support.
  • Confirm APN and network settings on the AT-5000 so it can reach the Plaspy endpoint from the cellular network.

Protocol Compatibility Notes​

  • Firmware variations across AT-5000 units can affect available features and message formats; verify the firmware version when troubleshooting.
  • Hardware revisions or optional modules may introduce minor protocol differences that affect how certain telemetry is reported.
  • Some features such as AGPS, phone call location request, or SMS hyperlinks depend on both device firmware and operator network behavior.
  • Transport selection (UDP vs TCP) is a device configuration choice; ensure the chosen transport is supported by the deployed firmware.
  • Plaspy automatically detects the tracker protocol, but accurate device identification (IMEI or device ID) is essential for proper mapping.
  • Always validate compatibility and configuration recommendations against the official ArkNav documentation for the exact device variant.

Why Protocol Understanding Matters​

Understanding how the AT-5000 communicates with Plaspy reduces configuration errors and speeds up troubleshooting when devices do not appear online or report unexpected data. A practical grasp of the communication flow also helps with network provisioning and lifecycle maintenance.

  • Helps ensure correct APN and reporting endpoint settings on the AT-5000 to reach d.plaspy.com or 54.85.159.138.
  • Aids in choosing the appropriate transport mode on the device when both UDP and TCP are supported.
  • Makes it easier to confirm that the device is sending its identification so Plaspy can automatically detect and map the protocol.
  • Supports informed decisions about power management, reporting intervals, and event triggers to match operational needs.
  • Provides context when coordinating with ArkNav support or cellular operators about connectivity and message delivery.

Why Use Plaspy with This Protocol​

Using the ArkNav AT-5000 with Plaspy provides a streamlined way to collect long term location and asset telemetry from rugged trackers designed for remote and harsh environments. Plaspy's automatic protocol detection and standardized endpoint simplify initial provisioning so devices can begin reporting with minimal platform-side configuration.
