Carscop - CCTR-810 Protocol

This page describes the public protocol context for using the Carscop CCTR-810 GPS tracker with Plaspy. It focuses on how the tracker communicates with the Plaspy platform in general, the role of connection settings, and the practical aspects you need to know to integrate and operate the device without exposing private implementation details.

The CCTR-810 is a GSM based tracker with a SIMCOM 340D module and an MTK GPS engine. It can buffer tracks when there is no GSM coverage and upload stored data later, and it supports event driven uploads such as when the vehicle stops for more than two minutes or when ACC turns off. Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol. Devices can be configured to report to the Plaspy endpoint at d.plaspy.com or 54.85.159.138 and communicate over port 8888 using either UDP or TCP. All devices in Plaspy use the same port and Plaspy automatically detects the tracker protocol, while exact device behavior may vary with firmware, hardware revision, and manufacturer implementation.

Protocol Overview​

The communication protocol for the CCTR-810 defines how the tracker reports location, status, alarms, and buffered records to a remote platform. In practice this means the device uses GPRS or SMS to send updates and may also accept remote commands via SMS when supported by the device. The protocol determines what data is sent, when uploads occur, and how the device identifies itself to a tracking server.

  • Enables the tracker to report GPS positions and status events to the server for real time monitoring.
  • Defines the identification method used by the tracker so the platform can associate incoming data with a device record.
  • Handles event notifications such as stop uploads, ACC off uploads, overspeed alarms, low battery alerts, and mileage reports.
  • Allows buffered data to be stored locally when offline and re uploaded once network connectivity is restored.
  • Supports remote control actions when the device accepts SMS or GPRS commands as part of its feature set.

How Plaspy Detects the Protocol​

Plaspy listens on a single shared endpoint and port for incoming connections from many supported trackers and uses automated detection to determine which protocol each device is using. In most cases, if the device is configured to report to the Plaspy endpoint the platform will identify and parse the incoming data automatically without manual protocol selection.

  • Plaspy accepts connections at the domain d.plaspy.com or the IP address 54.85.159.138.
  • The shared server port for all devices is 8888 which simplifies firewall and NAT rules.
  • Devices may be configured to use either UDP or TCP on port 8888 depending on their firmware and settings.
  • When the CCTR-810 sends data to the Plaspy endpoint, the platform detects the protocol and associates the messages with the correct device.
  • Users typically do not need to pick a protocol inside Plaspy if the tracker is pointed correctly to the Plaspy endpoint and port.

Transport and Connection Context​

Connection and transport choices affect reliability, firewall configuration, and how quickly data is delivered. The CCTR-810 supports GPRS for internet uploads and SMS for remote control and fallback messaging. It may be set to use either UDP or TCP when sending data to a tracking server.

  • The tracker can report to d.plaspy.com or directly to 54.85.159.138 depending on how you configure the device.
  • Communication to Plaspy uses port 8888 for both UDP and TCP and this same port is shared across all devices supported by Plaspy.
  • TCP can provide more reliable delivery while UDP may be used for lower overhead reporting depending on tracker firmware.
  • Ensure the tracker APN and GPRS settings are correct so the device can establish an internet connection before attempting to reach the Plaspy endpoint.
  • If SMS control is required, verify the device SIM and SMS center settings with the carrier and manufacturer guidance.

Protocol Compatibility Notes​

  • Firmware revisions can change message timing, event reporting behavior, and transport options. Always check the device firmware version when troubleshooting.
  • Hardware revisions or optional modules may add or remove features such as voice monitoring or specific alarm types.
  • Manufacturer side settings and default configuration can vary; some devices are shipped preconfigured for particular regional servers and may need reconfiguration to point at Plaspy.
  • Selection between UDP and TCP depends on device firmware capabilities and desired behavior for retries and delivery.
  • Offline buffering and reupload behavior is common with the CCTR-810 but the exact storage limits and recovery logic are determined by the device firmware.
  • Validate APN, server domain or IP, and port settings against the device manual and the Plaspy endpoint settings before deployment.

Why Protocol Understanding Matters​

Understanding how the CCTR-810 communicates helps ensure a reliable setup, faster troubleshooting, and consistent data flow into Plaspy. Knowing which events trigger uploads, how the device identifies itself, and how it behaves in low connectivity conditions reduces integration time and avoids common issues.

  • Helps confirm the device is pointing at the correct Plaspy endpoint and using port 8888 with the preferred transport.
  • Makes it easier to interpret why uploads occur at stops, on ACC off, or at configured intervals rather than at every position fix.
  • Simplifies troubleshooting of missing data by checking APN, GPRS connectivity, and buffered reupload behavior.
  • Supports planning for firewall and network rules since Plaspy uses a single shared port for all devices.
  • Assists in coordinating firmware updates or configuration changes with manufacturer documentation to maintain compatibility.

Why Use Plaspy with This Protocol​

Using Plaspy with the Carscop CCTR-810 provides a straightforward path to receiving real time location data, event alerts, and historical tracks. Plaspy’s automatic protocol detection and single port architecture reduce the configuration burden on installers and administrators, while the platform accepts data from trackers that buffer and reupload records when connectivity returns.
