Meitrack - T366 Protocol
This page describes the public protocol context for using the Meitrack T366 GNSS tracker with Plaspy. It focuses on how the device communicates with Plaspy at a high level, the connection settings commonly used in deployments, and the practical compatibility and configuration considerations that matter when integrating the T366 for fleet, marine, and industrial tracking.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when data is received. Exact protocol behavior and available features can vary by firmware version, hardware revision, and manufacturer implementation, so this page provides general guidance while encouraging verification against manufacturer documentation.
Protocol Overview
The protocol used by the T366 enables the tracker to identify itself to a remote collection endpoint, deliver GNSS fixes, report sensor and input telemetry, and send event notifications for alarms and immobilizer status. When paired with Plaspy, the protocol's role is to make location, timing, and sensor data usable by the platform without exposing device internals.
- Allows the device to transmit periodic and event driven location updates to Plaspy for real time visibility.
- Carries telemetry from RS232 peripherals, digital inputs, and relay/buzzer outputs so platform workflows can react to sensor data.
- Conveys device identity and basic status information so Plaspy can associate incoming messages with the correct asset record.
- Supports buffering and retransmission behavior so the T366 can preserve recent history when connectivity is interrupted.
- Enables remote commands and management workflows at the platform layer when manufacturer firmware and device configuration permit.
How Plaspy Detects the Protocol
Plaspy receives traffic at a single shared endpoint and port and automatically detects the tracker protocol based on the incoming device data. In most deployments the user only needs to configure the device to report to Plaspy; manual protocol selection inside Plaspy is usually not required when reporting is correctly set up.
- Plaspy server domain is d.plaspy.com and Plaspy server IP is 54.85.159.138 for device reporting.
- The port used by Plaspy for device connections is 8888 and is consistent across all supported devices.
- Plaspy automatically detects the tracker protocol once a device successfully reports to the platform endpoint.
- Users generally configure the T366 to point to the Plaspy endpoint and choose UDP or TCP as supported by the device and network.
- If issues occur, checking device reporting settings and network reachability to d.plaspy.com can resolve most detection problems.
Transport and Connection Context
The T366 may be configured to use either UDP or TCP depending on device firmware and deployment requirements. Both transport options are supported when pointing the device to Plaspy, and understanding the transport context helps ensure reliable data flow and firewall configuration.
- Devices may be configured to report to d.plaspy.com or directly to 54.85.159.138 depending on DNS and network policies.
- The port for device connections is 8888 and is used across all devices that report to Plaspy.
- Both UDP and TCP transport modes are supported by many trackers; choose the transport mode compatible with your SIM network and device settings.
- Ensure mobile operator APN and firewall settings allow outbound traffic to the Plaspy server and port to avoid blocked telemetry.
- For fleets in constrained networks or with special routing, coordinate with network administrators to permit traffic to the Plaspy endpoint.
Protocol Compatibility Notes
- Firmware variations can alter which telemetry fields are reported and which management commands are supported; always note the device firmware level.
- Hardware revisions and accessory configurations (external GNSS antenna, RS232 peripherals) influence available telemetry and required wiring.
- Manufacturer regional variants and radio band differences affect cellular connectivity and may influence reporting reliability in specific territories.
- Transport selection (UDP vs TCP) affects delivery characteristics; test both modes when establishing initial deployments.
- Offline buffering capacity, like the T366 8 MB buffer, helps preserve data during coverage gaps but exact buffering behavior is firmware dependent.
- Validate compatibility and feature availability against Meitrack documentation for the specific device serial number and firmware revision.
Why Protocol Understanding Matters
Understanding how the T366 communicates with Plaspy helps installers and administrators set up devices correctly, diagnose connectivity problems, and ensure that the platform receives the telemetry needed for operational workflows.
- Speeds up initial onboarding by ensuring the device reports to the correct Plaspy host and port.
- Helps troubleshoot issues caused by incorrect transport selection, APN configuration, or firewall restrictions.
- Clarifies which telemetry and events the platform can expect from a given firmware revision and accessory set.
- Informs decisions on remote management, OTA updates, and procedures for testing immobilizer and alarm workflows.
- Supports long term reliability planning by aligning device configuration with network and platform expectations.
Why Use Plaspy with This Protocol
Using Plaspy to ingest T366 telemetry provides centralized visibility, alerting, and reporting for fleets and assets operating in harsh environments. The combination of a rugged IP67-rated tracker and a platform that automatically detects incoming protocols simplifies deployments for organizations that require continuous tracking, remote immobilization, and integrated sensor telemetry.
Plaspy’s shared endpoint workflow reduces configuration friction by requiring devices to target a single server and port.
