AutoFon - Маяк 4.5 Protocol

This page describes the public protocol context for using the AutoFon Маяк 4.5 tracker with Plaspy. It focuses on how the device reports position and telemetry to a server and how that communication is interpreted from a platform integration perspective. The content here is intended to help administrators and integrators understand expected behavior without exposing sensitive implementation details.

The AutoFon Маяк 4.5 can report position by SMS and by sending interval GPRS packets to a chosen monitoring server. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device is configured to report to the Plaspy endpoint. Exact protocol behavior can vary by firmware, hardware revision, and manufacturer configuration, so device-specific behaviors should be validated against the manufacturer documentation when necessary.

Protocol Overview​

At a high level, the tracker protocol is the set of rules the AutoFon Маяк 4.5 uses to send location, status, and event data to a remote server or to authorized numbers by SMS. For Plaspy integration, the protocol determines how the device identifies itself, which telemetry fields it sends, and how alerts such as motion or power loss are encoded and delivered.

  • Enables periodic position reporting from the device to a remote monitoring endpoint over GPRS interval mode.
  • Allows SMS-based reports and remote commands as a fallback or alternative reporting channel.
  • Conveys status telemetry such as motion detection, battery state, and external power disconnect to the monitoring platform.
  • Supports event reporting for alarms, tamper or movement triggers so the platform can generate immediate alerts.
  • Forms the basis for Plaspy to map incoming messages to live map markers, history trails, and event notifications.

How Plaspy Detects the Protocol​

Plaspy receives device traffic at a single shared endpoint and port and automatically detects the tracker protocol used by an incoming device when messages arrive. In most cases users do not need to select a protocol manually inside Plaspy if the device is configured to report to Plaspy’s server.

  • Plaspy’s public server domain is d.plaspy.com which resolves to the platform endpoint.
  • The Plaspy server IP address is 54.85.159.138 for cases where numeric addressing is required.
  • Plaspy listens on port 8888 for device traffic and uses the same port for all supported devices.
  • Devices may be configured to use either UDP or TCP transport to deliver telemetry to Plaspy.
  • When a Mayak 4.5 is pointed at the Plaspy endpoint and sends reports, Plaspy identifies and processes its messages automatically.

Transport and Connection Context​

The transport and connection context describes how the AutoFon Маяк 4.5 reaches the server and which addressing options are commonly used. This context is useful for configuring APN settings on the device, firewall rules in networks, and for ensuring reliable delivery of telemetry.

  • The Mayak 4.5 can send GPRS interval packets to a configured monitoring server or send SMS reports to authorized numbers.
  • For Plaspy connectivity the device may use UDP or TCP transport on port 8888 depending on device configuration and firmware support.
  • Devices can be pointed to the Plaspy domain d.plaspy.com or the numeric address 54.85.159.138 as the destination for GPRS reports.
  • All devices in Plaspy use the same port, which simplifies firewall and network configuration for monitoring deployments.
  • Use the device’s configuration controls (SMS or configuration interface) to set the server address and transport if required by the tracker firmware.

Protocol Compatibility Notes​

  • Compatibility can depend on firmware version and hardware revision; different firmware builds may offer slightly different reporting options or field sets.
  • Transport mode (UDP vs TCP) is selectable on many devices and must match the device configuration to ensure delivery to Plaspy’s port 8888.
  • SMS reporting is a practical fallback for devices or networks where GPRS is intermittent, but SMS payloads and commands may vary by firmware.
  • Hardware variants or discontinued units may omit features listed on newer product pages; verify feature availability for the specific unit in hand.
  • Manufacturer configuration parameters such as APN, destination server, and authorized numbers must be set correctly for Plaspy ingestion.
  • Validate compatibility against manufacturer documentation when planning large deployments or when advanced features are required.

Why Protocol Understanding Matters​

Understanding how the tracker communicates with a monitoring platform reduces setup time, prevents common misconfigurations, and helps with troubleshooting if data is missing or malformed. Knowledge of the communication pattern also helps secure the deployment and set proper operational expectations.

  • Ensures correct APN and server settings so GPRS interval packets arrive at the Plaspy endpoint.
  • Helps select the appropriate transport mode (UDP or TCP) for the network environment and device firmware.
  • Makes it easier to interpret device behavior like heartbeat intervals, motion-triggered reports, and power-loss notifications.
  • Reduces troubleshooting time by clarifying whether an issue is network, device configuration, or firmware related.
  • Supports planning for battery life and reporting frequency tradeoffs when using long-term interval reporting.

Why Use Plaspy with This Protocol​

Using Plaspy to receive and process reports from AutoFon Маяк 4.5 devices provides a central, consistent way to visualize location data, monitor events, and manage alerts for assets or people. The combination of long battery life, motion detection, and dual reporting options (GPRS and SMS) makes this tracker a practical fit for deployments that need low-maintenance telemetry and reliable alerting rather than continuous high-frequency reporting.
