OKB Tehnoavtomatika - MPU-01GLONASS Protocol

This page provides public protocol context for using the OKB Tehnoavtomatika MPU-01GLONASS tracker with the Plaspy platform. It summarizes how the tracker communicates in general terms, what to consider when pointing devices at Plaspy, and which connection settings Plaspy expects. The MPU-01GLONASS is a compact GLONASS enabled tracker with a 24 channel NV08C-CSM receiver, support for GSM 900 and 1800 bands, SMS handling, and flexible input/output configuration that makes it suitable for many vehicle and asset tracking applications.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when the device reports to the platform. Plaspy's public endpoint information is d.plaspy.com and 54.85.159.138 on port 8888. Devices may be configured to use UDP or TCP on port 8888. Exact protocol behavior and message content can vary by firmware version, hardware revision, and manufacturer implementation, so device specific details should be validated against official OKB Tehnoavtomatika documentation.

Protocol Overview​

The device communication protocol is the set of rules the tracker uses to send position, status, and sensor data to a server and to receive configuration or command messages when supported. For integration with Plaspy the protocol plays a practical role in transforming raw GNSS fixes and peripheral signals into structured reports the platform can interpret.

  • Enables the tracker to report location fixes and basic telemetry to a remote server
  • Provides a means for the device to identify itself to a backend so reports are associated with the correct asset
  • Carries input and sensor state information from the device to the platform for monitoring and eventing
  • Allows the device to report SMS received or forwarded messages when that feature is enabled
  • Controls the frequency and content of reports based on device configuration and firmware settings

How Plaspy Detects the Protocol​

Plaspy automatically determines the incoming tracker protocol when a device connects and sends data to the shared endpoint. In most deployment scenarios you do not need to select a protocol manually inside Plaspy as long as the tracker is configured to report to Plaspy's public endpoint.

  • Plaspy listens for device reports at d.plaspy.com and at IP address 54.85.159.138
  • The platform uses a single port for all devices to simplify configuration and discovery
  • The port used by Plaspy for device connections is 8888
  • Devices may be configured to use either UDP or TCP when sending to Plaspy
  • If a device is correctly pointed to the Plaspy endpoint, Plaspy will detect its reporting format automatically

Transport and Connection Context​

Connection transport defines how packets reach Plaspy but does not itself define report semantics. The MPU-01GLONASS can be set to report over GSM networks to a server endpoint; on the Plaspy side the required transport context is intentionally consistent to ease device setup.

  • Devices can use UDP or TCP to send reports to Plaspy depending on device support and configuration
  • Plaspy accepts connections and reports at d.plaspy.com and 54.85.159.138
  • The single port Plaspy uses for device reporting is 8888 and is the same for all supported trackers
  • Use the transport option supported by your device and network environment when pointing to Plaspy
  • Ensure your APN and GSM settings on the tracker are correct so it can reach the Plaspy endpoint

Protocol Compatibility Notes​

  • Firmware revisions can change message content, available fields, or supported features; always verify firmware specifics
  • Hardware variants or optional I O modules may expose different sensors and inputs that affect reported data
  • Manufacturer configuration menus may offer options to select TCP or UDP transport and the server address to report to
  • Differences in how SMS is handled by a device can affect forwarding or remote configuration workflows
  • Transport selection (UDP versus TCP) can matter in lossy networks and should match the device capability and operator constraints
  • Validate compatibility and configuration steps against OKB Tehnoavtomatika documentation for your exact model and firmware

Why Protocol Understanding Matters​

Understanding the communication protocol helps you configure devices correctly, debug connectivity issues, and ensure the data Plaspy receives is usable for tracking and monitoring purposes. A practical awareness of how the tracker reports and what fields are typically included reduces integration time and improves operational reliability.

  • Makes it easier to confirm the device is sending expected data to Plaspy
  • Helps troubleshoot connectivity issues related to APN, transport, or server address
  • Guides configuration of inputs, outputs, and reporting intervals to match monitoring needs
  • Supports mapping device telemetry to Plaspy dashboards and alerts
  • Reduces ambiguity when updating firmware or switching hardware revisions

Why Use Plaspy with This Protocol​

Using Plaspy with the MPU-01GLONASS provides a straightforward path to translate GNSS fixes and peripheral signals into actionable fleet and asset intelligence. The combination of a compact GLONASS capable tracker and a platform that accepts a single shared endpoint simplifies large scale deployments and ongoing device management.
