Autoseeker - AT-25 Protocol
This page provides public protocol context for using the Autoseeker AT-25 GPS tracker with Plaspy. It explains how the tracker communicates in general terms, what connection settings are used to report data to Plaspy, and which aspects of device behavior are relevant to successful integration. The content here is intended to be informative and non sensitive while helping technical users understand how the AT-25 exchanges location and status information with a fleet server.
The AT-25 is compatible with Plaspy and supports reporting via SMS and GPRS TCP as well as modern 4G internet connectivity. 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 manufacturer implementation. Use this page as a high level reference and consult the device maker for firmware specific or advanced protocol details.
Protocol Overview
At a high level, the AT-25 communication protocol defines how the unit packages and sends position updates, alerts, and basic device status to a remote server such as Plaspy. The protocol enables the tracker to identify itself, report telemetry, and deliver event-driven messages that the platform can convert into locations, alerts, and history entries for operators.
- Enables periodic and event driven position reports so Plaspy can map and log vehicle location over time.
- Carries basic device identity and status information needed to associate incoming messages with a specific tracker.
- Transmits alerts and alarms such as overspeed, geofence events, low battery, and power loss so Plaspy can trigger notifications.
- Supports different reporting methods such as GPRS over cellular data and SMS fallback for resilient communication.
- Encodes reporting interval and status fields that allow the platform to present usable tracking history and operational insight.
How Plaspy Detects the Protocol
Plaspy receives incoming connections at a shared endpoint and automatically determines which tracker protocol each device is using. When an AT-25 is configured to send to the Plaspy endpoint, the platform will generally detect and interpret the reporting format without manual protocol selection in most cases.
- Plaspy listens on a single port for all supported devices and automatically detects the tracker protocol.
- Devices that are correctly configured to report to Plaspy do not usually require manual protocol selection inside the platform.
- The AT-25 can be set to report over GPRS TCP or via other supported transports and Plaspy handles detection at the server side.
- Proper device identity and consistent reporting help Plaspy match messages to records and avoid misclassification.
- If there are unusual firmware variants or non standard configurations, review manufacturer documentation to align reporting settings.
Transport and Connection Context
The AT-25 can use cellular data or SMS to deliver reports. For GPRS or 4G data reporting to Plaspy, the device may be configured to use either UDP or TCP on the common platform port. Plaspy exposes a stable endpoint that devices can target to ensure messages reach the fleet server.
- Plaspy server domain for device reporting is d.plaspy.com
- Plaspy server IP address is 54.85.159.138
- The platform uses port 8888 for device connections
- The device may be configured to use UDP or TCP on port 8888 depending on device support and carrier behavior
- All devices in Plaspy use the same port which simplifies device setup and firewall configuration
Protocol Compatibility Notes
- Firmware versions can introduce differences in message content, available fields, and behavior. Always note the device firmware when validating integration.
- Hardware revisions or regional variants of the AT-25 may have slightly different capabilities or default settings that affect reporting.
- Transport choice matters. Some networks prefer UDP for lightweight reporting while others use TCP for reliable delivery; confirm the device transport setting matches your needs.
- SMS based reporting is useful as a fallback but provides different data throughput and may not include the same set of telemetry fields as GPRS.
- Manufacturer default APN or server settings may need to be updated to point to the Plaspy endpoint for cloud reporting.
- Validate compatibility against the device user manual and the latest technical bulletins from the manufacturer.
Why Protocol Understanding Matters
Understanding how the AT-25 communicates helps ensure reliable installation, correct data interpretation, and faster troubleshooting when a device is not reporting as expected. Familiarity with the protocol and connection context reduces setup time and improves long term operational reliability for fleet managers.
- Reduces installation friction by aligning device server and transport settings with Plaspy expectations.
- Improves troubleshooting when data is missing or alerts are not arriving by narrowing the problem scope to transport, APN, or firmware differences.
- Helps optimize reporting intervals and battery tradeoffs to match operational needs and power constraints.
- Supports informed decisions about enabling features such as geofence, overspeed alerts, and remote engine cut based on device capability.
- Makes it easier to verify that messages arriving at Plaspy are being parsed and stored as intended.
Why Use Plaspy with This Protocol
Using the Autoseeker AT-25 with Plaspy gives organizations a practical way to collect location, status, and alert data from vehicles and present it in a centralized platform for monitoring and operational oversight. The AT-25 feature set such as timed reporting, SMS fallbacks, engine cut and various alarms pairs well with a cloud fleet server to deliver real time visibility and historical playback.
Plaspy is designed to accept device reports sent to a single endpoint and port, reducing configuration complexity across mixed fleets.
