GPSMarker - M100 Protocol
This page summarizes the public protocol context for using the GPSMarker M100 tracker with the Plaspy platform. It describes the role of the device reporting protocol in a general, non sensitive way and explains how the tracker communicates with Plaspy servers so integrators and administrators can configure reporting and validate connectivity. The information is intended to help with setup, troubleshooting, and compatibility checks while preserving manufacturer specific implementation details.
The GPSMarker M100 is a compact, long life GPS tracker with a 72 channel receiver, multiple sensors, and support for an open GPRS style protocol as described by the manufacturer. Plaspy uses shared connection settings across 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 device specific details should be validated against official GPSMarker documentation.
Protocol Overview
The communication protocol used by the M100 defines how the tracker reports position, sensor events, and status to a remote server and how the server can respond or acknowledge those reports. In practice the protocol is the bridge between the device hardware and Plaspy services, enabling location and telemetry to become usable data for monitoring and alerting.
- Enables the M100 to report position fixes, movement start events, crash or shock reports, temperature readings, and SOS alerts to a remote server.
- Provides a consistent identifier or device registration mechanism so Plaspy can associate incoming reports with the correct asset.
- Delivers telemetry in a form Plaspy can parse and translate into location history, alerts, and dashboard items without exposing firmware internals.
- Supports remote reporting over cellular data using an open GPRS style connection method as described by the manufacturer.
- Can be affected by firmware revisions or configuration parameters that change reporting intervals, event thresholds, or available sensor data.
How Plaspy Detects the Protocol
Plaspy operates a shared public endpoint for device reporting and includes automatic protocol detection so most trackers do not require manual protocol selection inside the platform. When the M100 is configured to report to Plaspy, the platform associates incoming connections with the correct device and protocol automatically.
- Plaspy listens for device connections on the public server d.plaspy.com and the companion IP address 54.85.159.138.
- All supported devices use the same network port in Plaspy, simplifying device configuration and routing inside the platform.
- Plaspy automatically detects the tracker protocol when the M100 sends valid reports to the Plaspy endpoint.
- In many deployments users only need to point the device to the Plaspy endpoint and set the transport type; manual protocol selection is typically not required.
- If a device fails to appear, checking device reporting settings, APN, transport type, and firmware version is the practical next step.
Transport and Connection Context
Connection choices such as UDP or TCP and the server address are part of the device configuration and determine how the M100 reaches Plaspy. The M100 can be configured to use either transport depending on model capabilities and deployment preferences.
- The M100 may be configured to report to Plaspy using UDP or TCP on port 8888 depending on device support and chosen configuration.
- Devices can point to the domain d.plaspy.com or to the server IP 54.85.159.138 when DNS resolution is not available or desired.
- Plaspy uses port 8888 for all devices, which standardizes deployment and firewall configuration for fleets.
- Selecting UDP versus TCP can affect delivery characteristics and retry behavior; choose the transport that matches the device settings and network environment.
- Ensure the device APN and mobile data plan allow outbound connections to the Plaspy endpoint and that any intermediate firewalls permit port 8888.
Protocol Compatibility Notes
- Manufacturer firmware revisions can change how the M100 structures or schedules reports; verify the device firmware level when troubleshooting.
- Hardware revisions and optional sensor configurations may affect which telemetry fields are present in reports.
- Transport selection (UDP or TCP) must match the device configuration to ensure successful reporting to Plaspy.
- The device supports open GPRS style reporting as noted by the manufacturer, but implementation details can vary by firmware.
- Validate compatibility against official GPSMarker documentation and firmware notes before large scale rollouts.
- Some sensor features such as panic SOS, crash detection, temperature monitoring, and relay control depend on hardware options and local configuration.
Why Protocol Understanding Matters
Understanding how the M100 communicates with Plaspy reduces friction during setup, increases reliability in production, and helps teams troubleshoot connectivity or data issues more efficiently. Protocol awareness also helps align device configuration with operational requirements and compliance needs.
- Ensures correct device configuration so location and sensor data arrive reliably at Plaspy.
- Helps administrators choose the appropriate transport and network settings for their environment.
- Aids in troubleshooting missing data by focusing checks on APN, transport, domain or IP, and firmware compatibility.
- Supports planning for battery life and reporting intervals by understanding how frequently the device transmits.
- Clarifies which sensor events will be reported to Plaspy so alerting and geofencing behave as expected.
Why Use Plaspy with This Protocol
Using Plaspy with the GPSMarker M100 gives organizations a straightforward path to convert device reports into actionable tracking data, alerts, and historical analysis. Plaspy’s shared endpoint model and automatic protocol detection remove much of the manual configuration burden, letting you focus on monitoring and operations instead of per device protocol selection.
