Astra Telematics - AT240 Protocol
This page summarizes the public protocol context for using the Astra Telematics AT240 tracker with Plaspy. It is focused on how the device communicates at a high level with Plaspy servers and what integration considerations you should be aware of when configuring reporting to the Plaspy platform.
Plaspy uses shared connection settings for all supported devices and automatically detects the tracker protocol when the device is correctly pointed at the Plaspy endpoint. Exact protocol behavior can vary by firmware version, hardware revision, and manufacturer implementation, so this page provides general guidance rather than firmware specific instructions.
Protocol Overview
The AT240 communicates telemetry, position, and basic device status to a remote server using the device's built in cellular link. The protocol governs how the tracker formats and sends those telemetry messages, how the server identifies the device, and how the server responds when applicable.
- Enables periodic and event driven position reporting so location and time stamped telemetry reach Plaspy.
- Provides a device identifier so Plaspy can associate incoming reports with the correct asset record.
- Carries operational information such as GPS fix status, movement events, and device health indicators in a transportable message form.
- Supports both continuous reporting and power saving modes depending on the device configuration and firmware behavior.
- Allows remote configuration and command delivery where the manufacturer exposes such capabilities and the transport supports it.
How Plaspy Detects the Protocol
Plaspy accepts device connections on its shared endpoint and port and performs automatic protocol detection for incoming device traffic. In most cases you do not need to pick a protocol inside Plaspy when the device is configured to report to the Plaspy endpoint.
- Plaspy’s public server domain for device reporting is d.plaspy.com and the public server IP is 54.85.159.138.
- All devices supported by Plaspy use the same port, port 8888, simplifying device configuration.
- Devices may be configured to use UDP or TCP to report to Plaspy on port 8888 depending on device support and preferences.
- When the AT240 is pointed at the Plaspy endpoint and actively reporting, Plaspy will detect the tracker protocol automatically.
- Typical setup work consists of ensuring APN and reporting address/transport are correct on the tracker and confirming the device firmware is configured to send telemetry.
Transport and Connection Context
The AT240 supports common cellular transports and can be configured to report to Plaspy using the transport option that best matches the deployment. Understanding transport behavior helps ensure reliable delivery of GPS and telematics data.
- The device may be configured using UDP or TCP on port 8888 to connect to Plaspy.
- Plaspy accepts device traffic addressed to d.plaspy.com or directly to 54.85.159.138 on port 8888.
- Because Plaspy uses the same port for all devices, setup often only requires setting the correct host and transport on the tracker.
- Choose UDP or TCP on the device based on network reliability, operator support, and any device firmware guidance from the manufacturer.
- Verify that the device APN and cellular settings allow outbound connections to the Plaspy endpoint and that any network firewalls permit the selected transport.
Protocol Compatibility Notes
- Firmware versions and feature sets can change how often the tracker reports, what events are emitted, and which configuration commands are supported.
- Hardware revisions or optional features such as CANBus or BLE may affect available telemetry fields and event types.
- Transport choice (TCP vs UDP) can influence delivery guarantees and how remote commands are acknowledged by the device.
- Manufacturer configuration options for sleep modes, internal memory buffering, and movement reporting intervals impact how real time the data appears in Plaspy.
- Validate compatibility and recommended settings against Astra Telematics documentation when planning large scale deployments.
- Where possible, test a small number of units in your target network environment to confirm behavior before wide roll out.
Why Protocol Understanding Matters
A solid grasp of how the AT240 communicates helps streamline setup, reduce troubleshooting time, and improve long term reliability of the device within Plaspy.
- Ensures correct host and transport settings so data reaches Plaspy without interruption.
- Helps interpret device behavior during onboarding such as delayed reports, buffered uploads, or missing telemetry.
- Informs decisions about transport selection, reporting intervals, and power saving configuration to match operational needs.
- Supports more effective communication with Astra Telematics support when firmware or feature differences affect integration.
- Aids in planning for firmware updates and validation of changes that can alter reported fields or event behavior.
Why Use Plaspy with This Protocol
Using the Astra Telematics AT240 with Plaspy provides a practical way to collect GPS, CANBus, and basic BLE related telemetry into a single platform for monitoring and fleet operations. Plaspy’s automatic protocol detection and shared connection settings reduce initial configuration overhead so devices can begin reporting with fewer manual steps.
