SinoTrack - ST-906 Protocol
This page describes the public protocol context for using the SinoTrack ST-906 with Plaspy. It focuses on how the device is typically configured to report to a third party platform, what role the reporting protocol plays in data delivery, and what to expect when integrating the ST-906 into Plaspy for live location, history, and telemetry.
Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol when a device reports to the platform. Exact protocol behavior for the ST-906 can vary by firmware version, hardware revision, and manufacturer implementation, so installers and administrators should validate device settings and firmware before large deployments.
Protocol Overview
At a high level, the ST-906 reporting protocol defines how the tracker identifies itself to a remote server, how it transmits location and telemetry, and how it accepts remote configuration via SMS to change reporting endpoints. The tracker is configured by SMS to point at a chosen server and APN so it can send position updates and other signals to an ingestion endpoint such as Plaspy.
- The protocol governs identification, timestamps, and the types of telemetry a device reports to the server without implying specific packet formats.
- SMS configuration is used to set the APN and the server address so the ST-906 can transmit over mobile data to a chosen platform.
- Reporting allows the server to receive periodic position updates, motion or ignition events, and other device signals supported by the unit.
- Protocol behavior can influence reporting frequency, message size, and which telemetry fields are included by the device.
- Proper APN and server configuration are essential for the device to successfully establish a data session and reach the chosen platform.
How Plaspy Detects the Protocol
Plaspy receives device reports at a shared ingestion endpoint and automatically determines the appropriate protocol for each device that connects. When an ST-906 is configured to report to Plaspy, the platform will ingest the device messages and map them into usable tracking data without requiring manual protocol selection by the user.
- Point the ST-906 at Plaspy by configuring the device server to d.plaspy.com or 54.85.159.138 using the device SMS commands.
- Plaspy listens on a single port for all devices and uses that endpoint to accept incoming device connections.
- The standard ingestion port used by Plaspy is 8888 and all devices supported by Plaspy use the same port.
- When the device reports to the Plaspy endpoint, the platform automatically detects the tracker protocol and processes incoming telemetry.
- In most cases users do not need to choose a protocol inside Plaspy if the device is correctly configured to report to the Plaspy server endpoint.
Transport and Connection Context
The ST-906 can be configured to use mobile data for reporting and typically relies on SMS for initial server and APN setup. For transport to Plaspy, the tracker may use either UDP or TCP depending on device settings and firmware capabilities. Use the correct network and APN settings for the SIM card installed in the tracker to ensure reliable connectivity.
- The device may be configured to report to d.plaspy.com or directly to 54.85.159.138 as the server address.
- Plaspy accepts device connections on port 8888 and all supported devices use that same port for data ingestion.
- Communication may use UDP or TCP on port 8888 depending on device configuration and network conditions.
- Configure the tracker APN and server address via the ST-906 SMS commands so the unit can open a data session to Plaspy.
- Verify mobile network availability and SIM APN settings in the target deployment area to avoid connectivity issues.
Protocol Compatibility Notes
- Firmware revisions can change which telemetry fields are reported, how often messages are sent, and which transports are supported.
- Hardware revisions and variant models may include different I O or sensor support that affects what the tracker reports to Plaspy.
- Manufacturer SMS command sets are the supported method to change APN and server settings on the ST-906; confirm the exact SMS syntax in the device manual.
- UDP versus TCP transport selection can affect delivery characteristics on cellular networks and should be chosen based on reliability needs and device capability.
- Confirm IMEI registration, local network band support, and regulatory requirements in the target country before deployment.
- Always validate a small number of units and confirm successful reporting to d.plaspy.com or 54.85.159.138 on port 8888 before large scale rollout.
Why Protocol Understanding Matters
Understanding the tracker communication protocol helps installers and administrators get devices online quickly, troubleshoot connectivity or data quality issues, and plan for long term maintenance and firmware updates. Clear knowledge of how the ST-906 reports and how Plaspy ingests data reduces time to first fix and improves operational reliability.
- Ensures correct APN and server settings are applied so the device can reach Plaspy over the mobile network.
- Helps diagnose missing or incomplete telemetry by correlating firmware capabilities with expected fields.
- Enables better planning for transport selection such as UDP or TCP based on network conditions and reliability needs.
- Supports controlled testing and validation during pilot deployments to confirm reporting cadence and history playback.
- Makes it easier to coordinate with installers and the device manufacturer when device behavior differs from expectations.
Why Use Plaspy with This Protocol
Using the SinoTrack ST-906 with Plaspy provides a practical path to real time vehicle tracking, history playback, and operational monitoring. Because the ST-906 can be pointed to a custom server and APN via SMS, fleet managers and installers can integrate device telemetry into Plaspy for mapping, alerts, and reports without needing the device manufacturer cloud.
Plaspy centralizes device ingestion on a single endpoint so you can manage mixed fleets and multiple tracker models using a consistent server address and port.

Note that protocol support, firmware behavior, and manufacturer device details can change over time; confirm the latest device specific protocol information and SMS command syntax on the manufacturer site https://www.sinotrackgps.com/ before deployment.
