AutoFon - Альфа-Маяк XL Protocol

This page describes the public protocol context for using the AutoFon Альфа-Маяк XL tracker with Plaspy. It explains how the device reports location and telemetry to Plaspy using commonly available transmission channels and the shared connection settings Plaspy exposes for compatible devices.

The Альфа-Маяк XL is a compact, long life GPS/GLONASS beacon designed to send position and status via SMS and GPRS. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device is pointed to the Plaspy endpoint. Exact protocol behavior can still vary by firmware version, hardware revision, and manufacturer implementation, so device behavior observed in the field may differ slightly from the general descriptions here.

Protocol Overview​

The protocol in this context refers to the device reporting behavior and the public-facing mechanisms the tracker uses to communicate position, state, and events to a remote monitoring platform. For the Альфа-Маяк XL, those mechanisms are primarily SMS and GPRS reporting over cellular networks, with a device-side buffer to retain data when connectivity is unavailable.

  • Enables delivery of periodic location fixes and event reports from the tracker to Plaspy.
  • Carries basic telemetry such as battery status, SOS triggers, and life signal messages for processing by the platform.
  • Supports dual delivery paths: SMS for messaging and GPRS for continuous reporting to cloud endpoints.
  • Provides reliable delivery through local buffering and retransmission when coverage is intermittent.
  • Allows remote configuration changes from the manufacturer or integrator that affect reporting frequency and behavior.

How Plaspy Detects the Protocol​

Plaspy receives incoming messages from devices at a single shared endpoint and uses that stream of incoming data to identify the device reporting format. In most deployments you do not need to manually select a protocol inside Plaspy when the tracker is correctly configured to report to the Plaspy endpoint.

  • Plaspy listens on a single, shared port for all devices supported by the platform.
  • Devices pointed to d.plaspy.com or to the Plaspy server IP are collected into the same intake pipeline.
  • When the Альфа-Маяк XL reports to the Plaspy endpoint, Plaspy will automatically detect the tracker reporting style and parse available fields.
  • Proper device configuration to the Plaspy endpoint is the primary requirement for automatic detection.
  • Users typically only need to ensure the device is configured to send to the Plaspy host and use the supported transport protocol.

Transport and Connection Context​

Transport context covers how the device sends its messages to Plaspy rather than the specifics of message encoding. The Альфа-Маяк XL can be configured to deliver reports over SMS or over GPRS. When using GPRS to reach Plaspy, the device may be set to use either UDP or TCP to send packets to the Plaspy endpoint depending on the device settings and carrier behavior.

  • Plaspy server domain for device reporting is d.plaspy.com and the public server IP is 54.85.159.138.
  • All Plaspy devices use the same listening port; the platform accepts device reports on port 8888.
  • The Альфа-Маяк XL may be configured to use UDP or TCP transport on port 8888 when reporting via GPRS.
  • SMS reports are delivered via the cellular network and are handled by the Plaspy intake system differently from GPRS messages.
  • Use of domain name or direct IP is possible; device configuration may accept either d.plaspy.com or the Plaspy server IP.

Protocol Compatibility Notes​

  • Firmware revisions can change report frequency, field names, or the exact behavior of event messages; always note firmware version when troubleshooting.
  • Hardware revisions or optional firmware builds may enable or disable features such as audio monitoring or extended telemetry.
  • Transport selection (SMS vs GPRS, UDP vs TCP) affects delivery reliability and battery consumption; choose based on deployment needs.
  • Some manufacturer-side configuration tools or accounts can alter device defaults used for Plaspy integration.
  • Local buffering behavior helps preserve data during outages but depends on the device configuration and firmware implementation.
  • Validate compatibility against official manufacturer materials and test a sample device before wide deployment.

Why Protocol Understanding Matters​

Understanding how the Альфа-Маяк XL reports to Plaspy helps ensure reliable setup, accurate troubleshooting, and predictable long term behavior for tracked assets. Knowing the transport and the kinds of messages the tracker will send reduces integration time and helps you interpret alerts and history data correctly.

  • Shortens setup time by ensuring device reporting is pointed to the correct Plaspy endpoint and transport.
  • Improves troubleshooting by clarifying whether an issue is network, transport, or device configuration related.
  • Helps optimize battery life by selecting appropriate reporting intervals and transport modes.
  • Ensures event handling such as SOS, life signals, and black-box delivery are correctly reflected in Plaspy alerts.
  • Supports planning for mixed fleets where some assets use SMS while others use GPRS reporting.

Why Use Plaspy with This Protocol​

Pairing the AutoFon Альфа-Маяк XL with Plaspy provides practical visibility for long term, low maintenance asset tracking. The tracker’s SMS and GPRS delivery options, combined with local buffering and event reporting, match common fleet and asset use cases where periodic reporting and reliable historical tracks are the priority.
