Autoseeker - AT-17C Protocol

This page describes the public protocol context for using the Autoseeker AT-17C with Plaspy. It focuses on how the device reports location and status to Plaspy and what to consider when configuring the tracker for reliable ingestion into the Plaspy platform. The intent is to provide useful, non-sensitive protocol context that supports successful integration and troubleshooting.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the unit is reporting to the Plaspy endpoint. The AT-17C can report via SMS or GPRS over the cellular network, and Plaspy accepts device traffic pointed to d.plaspy.com or 54.85.159.138 on port 8888. The device may be configured using UDP or TCP on port 8888, and exact protocol behavior can vary with firmware version, hardware revision, and manufacturer implementation.

Protocol Overview​

The AT-17C uses a device reporting protocol that lets it identify itself to a back end and deliver usable telemetry such as position, time, and alarm events. When configured for GPRS reporting the tracker sends periodic telemetry to Plaspy; when configured for SMS it can deliver position and respond to queries. The protocol's role is to enable reliable delivery of location and status while preserving battery life in long standby deployments.

  • Enables the tracker to report location, battery status, tamper alarms, and basic sensor signals to Plaspy.
  • Supports both GPRS TCP reporting for continuous telemetry and SMS reporting for low bandwidth or out of network uploads.
  • Provides identifiers and status fields that allow Plaspy to associate incoming messages with the proper device record.
  • Allows configurable reporting intervals and scheduled tracking modes so deployments can balance update frequency with battery life.
  • Delivers alarm events such as tamper or removal so Plaspy can generate immediate alerts for security workflows.

How Plaspy Detects the Protocol​

Plaspy listens for incoming device traffic on a single, shared endpoint and automatically detects the tracker protocol when a properly configured device reports. In most cases you do not need to choose a protocol inside Plaspy if the AT-17C is pointed at the Plaspy ingestion endpoint and using one of the supported transports.

  • Plaspy accepts device connections sent to d.plaspy.com or directly to 54.85.159.138 and listens on port 8888.
  • Devices can use TCP or UDP on port 8888 when configured for GPRS reporting and Plaspy will process the incoming telemetry.
  • For SMS reporting the device sends position and status messages that Plaspy ingests and maps to the same device record.
  • Because Plaspy uses a common port for all supported devices, the platform focuses on automatic protocol identification rather than requiring manual selection.
  • Proper device identifiers and consistent reporting intervals help Plaspy detect and maintain correct protocol handling for the AT-17C.

Transport and Connection Context​

Connection choices affect how the AT-17C delivers reports and how Plaspy receives them. The device supports GPRS reporting over TCP and can also fall back to SMS for telemetry or queries. When setting up the tracker, confirm whether GPRS or SMS is preferred for your coverage and battery requirements.

  • The AT-17C may be configured to use UDP or TCP on port 8888 for GPRS uploads to Plaspy.
  • Plaspy’s public ingestion endpoint is d.plaspy.com and the platform also accepts connections to 54.85.159.138 on port 8888.
  • All devices in Plaspy use the same port, which simplifies network configuration and platform ingestion.
  • SMS reporting remains a viable transport for periodic queries, low bandwidth areas, or backup reporting.
  • Transport selection can influence battery consumption and reporting reliability depending on signal conditions and reporting frequency.

Protocol Compatibility Notes​

  • Firmware versions can change message timing, fields, or reporting defaults; check the device firmware level when diagnosing differences.
  • Hardware revisions or regional variants may alter supported bands or the default transport mode between SMS and GPRS.
  • Some deployments prefer SMS as a primary or fallback transport where GPRS coverage or APN configuration is unreliable.
  • Ensure device APN and cellular settings match your SIM and network requirements to enable GPRS reporting to Plaspy.
  • Because Plaspy automatically detects protocols, most compatibility issues stem from device configuration or firmware behavior rather than platform settings.
  • Validate device behavior in a controlled test before large scale deployment to confirm reports appear in Plaspy as expected.

Why Protocol Understanding Matters​

Understanding how the AT-17C communicates helps ensure a smooth setup, reliable ongoing reporting, and faster resolution when issues occur. Knowing which transport the device uses, how often it reports, and what events it sends lets you optimize deployments for battery life and operational requirements.

  • Faster troubleshooting of missing or delayed reports by checking transport and endpoint settings.
  • Better battery life planning through informed selection of reporting intervals and modes.
  • Reliable alarm handling by ensuring tamper and removal events are included in telemetry.
  • More predictable deployments by testing firmware behaviors that affect reporting and scheduling.
  • Accurate device mapping in Plaspy by confirming unique identifiers and consistent reporting formats.

Why Use Plaspy with This Protocol​

Using the Autoseeker AT-17C with Plaspy provides a practical solution for long term asset visibility, tamper detection, and scheduled reporting. The AT-17C’s combination of long standby life, strong magnetic mounting, and the option to report via GPRS TCP or SMS makes it well suited for trailer, container, equipment, and marine asset tracking. Plaspy consolidates incoming telemetry and alarm events so fleet managers and security teams can access live positions, histories, and alerts from a single platform.
