Autoseeker - AT-12 Protocol

This page describes the public protocol context for using the Autoseeker AT-12 tracker with Plaspy. It focuses on how the device communicates with Plaspy servers in non-sensitive terms and what integrators and administrators should understand about on‑device reporting and connection behavior.

The AT-12 is a compact vehicle tracker with quad band GSM/GPRS capability and support for reporting via SMS and GPRS (TCP). 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 the manufacturer's implementation. Review the manufacturer documentation for device specific details when needed.

Protocol Overview​

The communication protocol of the AT-12 defines how the tracker reports location, status, and alarms to a remote server and how it can receive commands or configuration updates. For integration with Plaspy the important aspects are the device's ability to establish a data session and to send standard tracking events that Plaspy can map to its platform.

  • Enables the tracker to report GPS position, movement state, and basic status to a remote endpoint.
  • Supports reporting over cellular networks using SMS and GPRS TCP modes as provided by the device.
  • Allows the tracker to identify itself to the server so incoming messages are associated with the correct device record.
  • Transmits periodic and event driven messages used for live tracking and history records.
  • Interacts with on device features such as motion detection and power management to control reporting frequency.

How Plaspy Detects the Protocol​

Plaspy receives device reports at a single shared endpoint and automatically identifies the tracker protocol so users generally do not need to select a protocol manually within Plaspy when the device is correctly configured to report. Proper device configuration to point at the Plaspy endpoint is typically the main step required.

  • Plaspy server domain for reporting is d.plaspy.com.
  • Plaspy server IP is 54.85.159.138.
  • Plaspy uses port 8888 for device connections.
  • Devices may be configured to use either UDP or TCP on port 8888 when reporting to Plaspy.
  • Plaspy uses the same port for all supported devices and automatically detects the tracker protocol.
  • If a tracker is configured to point to the Plaspy endpoint and can reach the server, Plaspy will attempt to decode the incoming messages and associate them with the correct device.

Transport and Connection Context​

The AT-12 can report data over the cellular data channel and may also support SMS for alerts or fallback. When integrating with Plaspy, the transport choice and the configured server address determine how the device reaches Plaspy for regular tracking.

  • The device may be configured to use UDP or TCP on port 8888 depending on device support and user configuration.
  • Devices can point to the Plaspy domain d.plaspy.com or to the server IP 54.85.159.138; either address routes reports to Plaspy.
  • Plaspy accepts device connections on port 8888 for all supported trackers.
  • Using TCP may be preferable for persistent sessions while UDP can be used where the device firmware favors stateless reporting.
  • Ensure the device APN and GPRS settings are correct so the tracker can establish a data session to reach the Plaspy endpoint.
  • SMS reporting is commonly used for alerts or fallback but requires separate handling outside standard TCP/GPRS reporting.

Protocol Compatibility Notes​

  • Firmware versions may change how frequently the device reports, which event types are sent, or which transport modes are available.
  • Hardware revisions can introduce small differences in behavior; verify device model and revision when troubleshooting.
  • Some device behavior, such as automatic time zone adjustment and power management, is controlled on device and affects timestamping and reporting cadence.
  • Transport selection (TCP vs UDP) should match what the device firmware supports and what is configured on the device.
  • Manufacturer settings and optional features (for example motion detection sensitivity) can affect the volume and type of reports sent to Plaspy.
  • Always validate compatibility against the official Autoseeker documentation for the specific AT-12 firmware level you are deploying.

Why Protocol Understanding Matters​

Understanding how the AT-12 communicates helps ensure reliable setup, efficient use of cellular data, and faster troubleshooting when devices do not appear in Plaspy. Clear expectations about reporting behavior make it easier to align device configuration with operational needs.

  • Helps confirm the device is pointing to the correct Plaspy endpoint and using the supported transport.
  • Improves troubleshooting speed when messages are delayed or missing by narrowing scope to network, device config, or firmware.
  • Guides decisions about reporting intervals and power management to balance battery life and location freshness.
  • Enables more predictable integration when using advanced features like motion triggered reporting or scheduled daily reports.
  • Supports validation of device identity and mapping of incoming messages to the correct asset in Plaspy.

Why Use Plaspy with This Protocol​

Using the Autoseeker AT-12 with Plaspy provides a straightforward way to collect location and status data from vehicles and bring that data into a single platform for monitoring, reporting, and operational oversight. Plaspy’s automatic protocol detection and shared connection settings reduce the need for manual protocol selection when a device is correctly configured to report to the Plaspy endpoint.
