PST - PST-AVL01 Protocol
This page provides a public, high level description of the communication protocol context for the PST PST-AVL01 when used with Plaspy. It explains how the tracker reports location and event data to Plaspy and what role the device protocol plays in that exchange, without exposing private implementation details.
The PST-AVL01 is a GPS GSM GPRS tracker designed for real time vehicle tracking and fleet management. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, but exact protocol behavior can vary by firmware version, hardware revision, and official manufacturer implementation. This page helps you understand that general context so you can configure and validate the device for use with Plaspy.
Protocol Overview
At a public level, the tracker protocol defines how the PST-AVL01 identifies itself, reports GPS fixes and status events, and exchanges commands or responses with a server such as Plaspy. The protocol enables the tracker to deliver usable location, connectivity, and alert information for monitoring and fleet workflows.
- Provides a structured way for the device to send location updates and status events to the server
- Carries identifying information so Plaspy can associate reports with the correct asset
- Allows delivery of alerts and auxiliary inputs such as SOS or immobilization triggers
- Includes transportable messages that Plaspy converts to consistent telemetry for dashboards and reports
- Operates within the device firmware and manufacturer implementation, which determines exact message timing and optional features
How Plaspy Detects the Protocol
Plaspy is designed to accept reports from many tracker models using a single shared endpoint and port, then determine the device protocol automatically. When properly configured to report to Plaspy, the PST-AVL01 will typically be recognized and mapped to the correct device record without manual protocol selection inside Plaspy.
- Plaspy public endpoint domain is d.plaspy.com and the server IP is 54.85.159.138
- Plaspy listens on a single port used by all devices supported by the platform
- Devices may be configured to report using either UDP or TCP to the Plaspy endpoint
- Plaspy automatically detects the tracker protocol so manual selection is usually unnecessary
- Proper device identifier configuration on the tracker side helps Plaspy match reports to the correct asset
Transport and Connection Context
Connection context covers how the PST-AVL01 reaches the Plaspy server and which transport options are available. The tracker uses the cellular data channel to send packets to Plaspy and can be pointed to the platform using either the domain name or the provided IP address.
- The PST-AVL01 may be configured to send data to d.plaspy.com or directly to 54.85.159.138
- Devices may use UDP or TCP depending on device support and local configuration
- Plaspy listens on port 8888 for incoming tracker connections and reports
- All devices in Plaspy use the same port to simplify device configuration and server routing
- Select the transport that your firmware and SIM plan support for best reliability
Protocol Compatibility Notes
- Firmware revisions can change message timing, optional fields, and supported commands
- Hardware revisions or regional variants of the PST-AVL01 may behave slightly differently
- Manufacturer configuration menus or SMS command sets may determine whether the tracker uses UDP or TCP
- Always verify that the tracker is configured to report to d.plaspy.com or the server IP and to use port 8888
- Plaspy automatically detects the protocol, but correct device identifiers and APN settings are needed on the tracker
- If custom manufacturer firmware is present, double check compatibility before large scale deployment
- Confirm supported features such as geo-fencing or immobilization in the device documentation
Why Protocol Understanding Matters
Understanding the public protocol context helps ensure successful setup, reliable reporting, and effective troubleshooting when integrating PST-AVL01 devices with Plaspy. Awareness of transport choices, identification behavior, and firmware variability reduces setup time and avoids common integration pitfalls.
- Helps you choose the correct transport mode and server address on the device
- Ensures device identifiers are set so Plaspy can match incoming reports to assets
- Makes it easier to diagnose connectivity or reporting gaps between device and platform
- Informs decisions about firmware updates and bulk deployment practices
- Supports consistent expectations around feature availability such as SOS alerts or geo-fence events
Why Use Plaspy with This Protocol
Pairing the PST-AVL01 with Plaspy provides a straightforward path to real time vehicle visibility and fleet management. Plaspy accepts the device reports, normalizes telemetry, and surfaces location and event data for operational monitoring, routing, and alerting needs. For organizations that need to track vehicles, respond to alerts, or analyze fleet performance, this combination delivers reliable, cellular based reporting and a single platform to consume the data.
