Autoseeker - AT-9 Protocol

This page describes the public protocol context for using the Autoseeker AT-9 tracker with Plaspy. It focuses on how the AT-9 communicates with the Plaspy platform at a high level and which shared connection settings are used to route device reports into Plaspy for real time tracking and telemetry.

Plaspy uses a single shared endpoint and port for all supported trackers and automatically detects the device protocol once the tracker is configured to report to the Plaspy endpoint. Exact packet behavior, command availability, and feature handling can vary by AT-9 firmware version, hardware revision, and manufacturer settings, so this page describes public, non sensitive integration context and practical considerations for setup and troubleshooting.

Protocol Overview​

The communication protocol for the AT-9 defines how the device reports location, sensor telemetry, alarms, and optional two way voice or SOS events to a backend platform like Plaspy. In general terms the protocol enables identification, periodic or event driven reporting, and delivery of status information that Plaspy can present to users and APIs.

  • Carries GNSS and assisted positioning data plus fallbacks such as Wi Fi and LBS so Plaspy can display location and history.
  • Transmits alarm and sensor events including motion, vibration, tamper, displacement, and low battery to trigger alerts.
  • Delivers telemetry such as battery state and network status to support operational monitoring and reporting.
  • Supports event driven messages for SOS and two way voice initiation so incident workflows can be created in Plaspy.
  • Allows configuration commands and remote settings when supported by the device and manufacturer provisioning.

How Plaspy Detects the Protocol​

Plaspy accepts device connections at a shared endpoint and port and will attempt to identify the tracker protocol automatically when a device begins reporting. In practice this means that properly configured AT-9 units will be recognized by Plaspy without requiring manual protocol selection in most deployments.

  • Plaspy listens on a single port for all devices and automatically detects the tracker protocol.
  • Devices should be configured to report to the Plaspy server endpoint to enable automatic detection and ingestion.
  • The common Plaspy server domain is d.plaspy.com and the public Plaspy server IP is 54.85.159.138 for direct addressing.
  • The shared port used for device reporting is 8888, which Plaspy uses across supported devices.
  • If the AT-9 is set to send data to the Plaspy endpoint over the network, Plaspy will process incoming reports and map them into the tracking workflow.

Transport and Connection Context​

The AT-9 can be configured to use either UDP or TCP transport depending on the device configuration and network environment. Plaspy supports both transports on the shared Plaspy port so administrators can select the mode that best matches device firmware and connectivity reliability.

  • Devices may be configured to send reports to d.plaspy.com or directly to 54.85.159.138.
  • Plaspy uses port 8888 for both UDP and TCP reporting and all devices in Plaspy use the same port for consistency.
  • Choose UDP when lower overhead and simpler NAT traversal are acceptable, or TCP when delivery confirmation and session orientation are preferred by the device firmware.
  • Ensure carrier APN and SIM provisioning allow outbound connections to the Plaspy endpoint and port.
  • Network elements such as firewalls and NAT should permit the chosen transport on port 8888 so the tracker can reach Plaspy reliably.

Protocol Compatibility Notes​

  • Manufacturer firmware revisions can change message content, feature flags, or optional command sets that affect integration with Plaspy.
  • Hardware revisions or optional accessories may expose additional telemetry channels that Plaspy can ingest when present.
  • Transport selection between UDP and TCP may be limited by device firmware; confirm which transport modes your AT-9 unit supports.
  • Some features such as two way voice or accessory inputs depend on carrier support and local regulatory or network conditions.
  • Validate device SIM provisioning, APN settings, and server address configuration against the manufacturer documentation before wide deployment.
  • When in doubt, consult official Autoseeker materials for firmware specific behaviors and configuration steps.

Why Protocol Understanding Matters​

Understanding the AT-9 communication protocol and how it interfaces with Plaspy helps ensure a smooth setup, reliable reporting, and faster troubleshooting when issues arise. Clear protocol context reduces guesswork when validating device connectivity and interpreting telemetry behavior in the platform.

  • Speeds up initial provisioning by matching AT-9 reporting settings to the Plaspy endpoint and transport.
  • Improves fault isolation for intermittent reports by clarifying whether issues are network, SIM, transport, or device related.
  • Helps tune reporting intervals and alarms to balance battery life and operational visibility.
  • Ensures alarm and SOS workflows behave as expected in Plaspy by confirming which events the tracker will send.
  • Reduces deployment risk by aligning expectations around firmware and hardware limitations prior to roll out.

Why Use Plaspy with This Protocol​

Using the Autoseeker AT-9 with Plaspy provides durable, low power asset tracking combined with a consistent server endpoint and automatic protocol detection. For organizations managing vehicles, containers, or remote equipment, the AT-9’s rugged design, multi mode positioning, and alarm set integrate with Plaspy to deliver situational awareness, historical routes, and alerting without requiring complex per device configuration inside the platform.

Plaspy accepts AT-9 reports on the shared Plaspy endpoint and port and will automatically detect the device protocol when the tracker is configured to report to the platform.
