Astra Telematics - AT210 Protocol
This page covers the public protocol context for using the Astra Telematics AT210 tracker with Plaspy. It focuses on the communication relationship between the AT210 and the Plaspy platform, explaining the connection context and what to expect from the tracker reporting behavior in general, without exposing private implementation details.
The AT210 is a rugged, IP67 rated GPS tracker built around a Cortex M3 processor and SiRFStar IV GPS chipset and supports GPRS as well as TCP and UDP transport modes. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol, while exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation. Users should confirm device-specific behavior against manufacturer documentation when needed.
Protocol Overview
The protocol used by the AT210 governs how the device reports location, status, and event information to a remote server and how configuration or command messages are exchanged when applicable. In the context of Plaspy, this protocol enables the tracker to identify itself, transmit usable telemetry, and participate in remote monitoring workflows.
- Carries device identification and status so Plaspy can associate incoming data with the correct asset
- Transports periodic location updates and event driven reports such as movement or input changes
- Conveys telemetry needed for mapping, timestamping, and basic diagnostics without exposing firmware internals
- Enables over the air configuration or remote commands where the manufacturer and firmware permit it
- Works over mobile data networks using the tracker modem and the network transport selected by the device
How Plaspy Detects the Protocol
Plaspy is designed to accept data from many tracker models using a single, shared server endpoint and automatically detect the incoming protocol so manual selection is typically unnecessary. If an AT210 is configured to report to Plaspy, the platform will associate received messages with the correct device and parse them using safe, supported handlers.
- Plaspy accepts device reports at the shared endpoint d.plaspy.com and at the public server IP 54.85.159.138
- The listening port for Plaspy is 8888 and all devices supported by Plaspy use this same port
- Devices may be configured to use either UDP or TCP transport on port 8888 depending on the tracker settings
- Because Plaspy automatically detects the tracker protocol, a correct device configuration pointing at the Plaspy endpoint is usually sufficient
- If a device does not appear, checking device reporting settings, APN, and firmware behavior is the first troubleshooting step
Transport and Connection Context
Understanding the transport and connection layer helps ensure the AT210 can reach Plaspy reliably over the cellular network. The AT210 supports GPRS and can be set to use TCP or UDP depending on the device firmware and configuration choices.
- The AT210 may be configured to send data to d.plaspy.com or directly to 54.85.159.138
- Plaspy receives tracker traffic on port 8888 and the device can use either UDP or TCP on that port
- Choosing TCP can help with delivery guarantees on unreliable links while UDP may reduce overhead where supported by the device
- Ensure the tracker APN, SIM data plan, and network coverage are appropriate for continuous reporting
- When testing, confirm the device is pointing at the Plaspy endpoint and that the carrier does not block the chosen transport
Protocol Compatibility Notes
- Firmware revisions can change message frequency, supported transport modes, and available settings; check the device firmware version
- Hardware revisions or variant models sometimes alter available IO or optional features referenced in reports
- Manufacturer configuration utilities and default settings may differ between production runs or regional variants
- Selecting TCP versus UDP may affect behavior; confirm which transports are supported and stable for your deployment
- Always validate compatibility in a controlled environment before wide deployment to confirm Plaspy receives expected reports
- Refer to Astra Telematics documentation for firmware specific notes and feature availability
Why Protocol Understanding Matters
A practical understanding of how the AT210 communicates with a server like Plaspy helps with setup, operational reliability, and targeted troubleshooting. Knowing the broad characteristics of the tracker protocol reduces guesswork when devices do not appear in the platform or when telemetry looks incomplete.
- Helps verify correct device pointing to d.plaspy.com or 54.85.159.138 and the use of port 8888
- Guides APN and SIM configuration to ensure cellular connectivity and data delivery
- Clarifies why firmware updates or hardware variants may change reported fields or event behavior
- Supports faster resolution of connectivity issues by narrowing down transport and reporting settings
- Informs decision making about power management and reporting intervals that impact battery life
Why Use Plaspy with This Protocol
