Sanav - CT-58 Protocol
This page covers the public protocol context for using the Sanav CT-58 mini GPS tracker with Plaspy. It explains how the tracker communicates with Plaspy at a high level, what connection settings are used, and which aspects of the device behavior are most relevant when integrating the CT-58 for vehicle, container, or asset tracking.
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 CT-58 can vary depending on firmware version, hardware revision, and manufacturer implementation, so this page focuses on public, non-sensitive protocol context and practical integration considerations.
Protocol Overview
The communication protocol for the CT-58 defines how the device reports location, movement, and alert events to a remote server so that Plaspy can record and present tracking data. In practice this means the tracker sends periodic or event driven reports over a network transport to the Plaspy endpoint, and the platform interprets those reports to generate location updates, status events, and alerts.
- Enables the CT-58 to report GPS fixes, movement events from the vibration sensor, and optional SOS alerts to Plaspy.
- Carries identifying information so the platform can associate incoming reports with the correct device record.
- Supports periodic reporting and event driven messages so the device can minimize power while still delivering timely updates.
- Provides metadata used by Plaspy for location accuracy, movement detection, and alert classification.
- Acts as the bridge between CT-58 hardware features such as the vibration sensor and optional panic button and Plaspy platform features.
How Plaspy Detects the Protocol
Plaspy receives reports from devices at a shared network endpoint and automatically detects the tracker protocol in use. For most installations, if the CT-58 is configured to send reports to the Plaspy endpoint, no manual protocol selection inside the platform is required.
- Plaspy listens on a single port for all supported devices and uses that shared endpoint to receive reports.
- Plaspy automatically detects the tracker protocol when a correctly addressed device sends data to the endpoint.
- Users typically only need to configure the CT-58 to point to the Plaspy server and choose the desired transport protocol on the device.
- Proper device identification and consistent reporting intervals help Plaspy associate messages with the correct asset.
- If reporting fails, verify device settings and server addressing first before making platform changes.
Transport and Connection Context
Connection context covers how the CT-58 reaches Plaspy on the network and which addressing and transport options are commonly used. These are the public settings that the device and network should be configured to use.
- Devices may be configured to report to d.plaspy.com or directly to the Plaspy server IP 54.85.159.138.
- The common port used by all devices in Plaspy is 8888 and the CT-58 may be set to use UDP or TCP on that port depending on device support.
- Plaspy supports both UDP and TCP transports on port 8888 so choose the transport that matches the CT-58 firmware and network environment.
- Ensure the device APN and GSM settings allow outbound connections to the Plaspy endpoint.
- Network firewalls and carrier restrictions should allow traffic to d.plaspy.com or the server IP on port 8888.
Protocol Compatibility Notes
- The CT-58 is compatible with Plaspy when the device is configured to report to the Plaspy endpoint and transport settings match device capabilities.
- Firmware versions can change message behavior, reporting intervals, and supported transports; check the device firmware level when troubleshooting.
- Hardware revisions and optional accessories such as an external panic button can affect which events the tracker reports.
- Some deployments prefer TCP for reliable delivery while others use UDP for lower overhead; confirm which transport the CT-58 firmware supports.
- Manufacturer-side configuration menus and default settings may differ between units; validate the device configuration before testing with Plaspy.
- Always consult official Sanav documentation for the CT-58 to confirm firmware specific details and recommended configuration.
Why Protocol Understanding Matters
Understanding the CT-58 communication protocol helps ensure reliable setup, faster troubleshooting, and predictable long term operation when the device is used with Plaspy. Clear knowledge of what the device sends and how Plaspy receives it reduces configuration errors and improves monitoring accuracy.
- Helps verify the device is pointing to the correct Plaspy endpoint and using the supported transport.
- Makes it easier to interpret telemetry such as vibration triggered events and SOS reports.
- Reduces time spent diagnosing missing or delayed reports by isolating network, transport, and device configuration issues.
- Supports planning for power and reporting tradeoffs when configuring periodic versus event driven reporting.
- Improves confidence that device behavior matches operational needs such as asset or vehicle monitoring.
Why Use Plaspy with This Protocol
Using the Sanav CT-58 with Plaspy gives organizations a practical path to collect GPS locations, vibration based movement reports, and optional SOS alerts in a centralized fleet and asset monitoring platform. The CT-58's small form factor, built in vibration sensor, and optional panic button make it well suited for discreet asset tracking and vehicle protection, while Plaspy handles incoming reports, stores history, and surfaces events for operational use.
