Meitrack - MVT-340 Protocol
This page covers the public protocol context for using the Meitrack MVT-340 with Plaspy. It is intended to explain, at a high level, how the tracker communicates and how that communication is consumed by Plaspy without exposing private implementation details. The MVT-340 is a compact vehicle tracker designed for real time tracking, geo fencing, an S O S alert button, sleep mode, AGPS assistance, and speeding alerts, making it suitable for vehicles from taxis to company fleets.
Plaspy uses shared connection settings across all supported devices and automatically detects the tracker reporting protocol when the device is correctly pointed at the Plaspy endpoint. Exact behavior for any device can vary by firmware version, hardware revision, and manufacturer implementation, so understanding the general protocol context helps when configuring and troubleshooting MVT-340 units for use with Plaspy.
Protocol Overview
The device protocol is the set of rules the MVT-340 uses to report position, status, and alerts to a remote server. In practice, the protocol defines how the tracker identifies itself, how it sends periodic or event driven messages, and how the server acknowledges or processes those messages so they become usable location and status data in a platform such as Plaspy.
- The protocol lets the MVT-340 send location updates, alerts, and status messages to a remote server.
- Identification fields in the report allow Plaspy to associate messages with a specific tracker device and convert raw messages into meaningful telemetry.
- Event messages such as S O S alerts, geo fence breaches, and speeding notices are transported alongside routine position reports.
- The protocol enables server side systems to interpret battery, ignition, and motion status for operational use.
- Plaspy receives the device messages and translates them into platform events, maps, and reports for fleet visibility.
How Plaspy Detects the Protocol
Plaspy accepts incoming connections on a shared endpoint and identifies the incoming tracker protocol automatically when a device sends data to the platform. In most setups you do not need to choose a protocol in Plaspy if the MVT-340 is configured to report correctly to the Plaspy endpoint.
- Plaspy listens on a single, shared port for all device connections and uses automatic protocol detection to determine how to parse incoming messages.
- Pointing the MVT-340 to the Plaspy server domain d.plaspy.com or to the Plaspy server IP 54.85.159.138 on the configured port is the typical way to connect.
- All devices in Plaspy use the same port which simplifies deployment and device provisioning.
- When the tracker reports to the Plaspy endpoint, Plaspy associates the incoming data stream with the appropriate device entry and converts messages into usable telemetry.
- Proper device configuration at the tracker side is the most common requirement to allow automatic detection to succeed.
Transport and Connection Context
Connection transport refers to the underlying network protocol used to deliver messages from the MVT-340 to Plaspy. The MVT-340 may be configured to use different transports depending on device settings and network conditions. Understanding the transport context helps ensure devices reliably reach the Plaspy servers.
- The device may be configured to use UDP or TCP on port 8888 depending on device support and local configuration.
- Devices can be pointed to the Plaspy domain d.plaspy.com or directly to the Plaspy server IP 54.85.159.138 when setting the report address.
- Plaspy uses port 8888 as the common port for all supported devices, which reduces configuration complexity for fleets.
- Choosing UDP or TCP on the tracker affects delivery characteristics such as retransmission behavior and should match the tracker configuration.
- Network and firewall rules must allow connections from the device network to d.plaspy.com or 54.85.159.138 on port 8888.
Protocol Compatibility Notes
- Firmware versions can change message behavior and available features, so verify the MVT-340 firmware level when assessing compatibility.
- Hardware revisions or regional variants of the MVT-340 may implement features or message fields differently.
- Transport selection between UDP and TCP may be limited by the specific firmware build or device configuration options.
- Manufacturer side defaults for reporting intervals or event generation can affect how frequently data arrives at Plaspy.
- If you plan remote configuration or command delivery, confirm the device supports the needed command set with your firmware revision.
- Always validate device setup against the latest manufacturer documentation for the most accurate device specific behavior.
Why Protocol Understanding Matters
Knowing how the MVT-340 communicates with a server helps ensure reliable setup, faster troubleshooting, and predictable long term operation when the device is used with Plaspy. A clear view of the protocol and transport context reduces guesswork during rollout and makes it easier to interpret device behavior.
- Proper device pointing and transport selection prevent common connectivity problems.
- Understanding identification and reporting patterns accelerates device onboarding in Plaspy.
- Awareness of firmware dependent behaviors helps prioritize updates or configuration changes.
- Protocol level knowledge assists in diagnosing missing data, intermittent reports, and alert mismatches.
- Clear expectations around event messages like geo fence or S O S improve operational procedures.
Why Use Plaspy with This Protocol
Using the Meitrack MVT-340 with Plaspy provides a straightforward path to turning tracker reports into vehicle location, status, and alerting for operational visibility. For organizations that need real time location monitoring, geo fence enforcement, and quick access to S O S events, combining the MVT-340 hardware with Plaspy's shared endpoint and automatic protocol detection can simplify deployment and ongoing management.
