GOTOP - TL-216 Protocol

This page describes the public protocol context for using the GOTOP TL-216 tracker with Plaspy. It focuses on how the tracker communicates with Plaspy in non sensitive terms and summarizes the connection settings you can use to point TL-216 devices to Plaspy for reporting and monitoring.

Plaspy uses shared connection settings across supported devices and automatically detects the tracker protocol on incoming connections. Exact protocol behavior and message content for the TL-216 can vary by firmware version, hardware revision, and how the manufacturer implements reporting over GSM GPRS or SMS, so consider this a high level integration reference.

Protocol Overview​

The TL-216 uses GPS positioning with GSM GPRS or SMS transport to deliver location and status to backend servers. When configured to report over GPRS, the device sends periodic location updates, movement events, geofence alerts, and battery status to a remote server endpoint. Plaspy receives those reports and maps them into the platform UI and logging system.

  • Enables the device to report GPS fixes, last known location, and movement events to a remote server
  • Transports telemetry such as battery level, sleep or standby state, and basic status alongside location
  • Allows configuration of reporting interval and alarm triggers like geofence breaches through device settings
  • Provides data continuity by storing reports locally when GSM network is unavailable and forwarding on reconnect
  • Supports both SMS reporting for direct phone alerts and GPRS reporting for server integration and fleet visibility

How Plaspy Detects the Protocol​

Plaspy accepts incoming connections on a single, shared endpoint and inspects incoming traffic to automatically determine the tracker reporting protocol. In most cases you do not need to manually select a protocol inside Plaspy if the TL-216 is correctly configured to send reports to the Plaspy endpoint.

  • Plaspy listens on the common server endpoint d.plaspy.com and the IP 54.85.159.138
  • All devices in Plaspy use the same port for reporting which simplifies device configuration
  • Plaspy automatically detects the tracker protocol when a device connects to the shared endpoint
  • Users typically only need to point the TL-216 to the Plaspy endpoint using the device configuration method they prefer
  • If a device uses SMS reporting, that remains outside the TCP or UDP server detection flow and is handled separately by the user or carrier

Transport and Connection Context​

TL-216 devices can use GPRS to report to a remote server and may be configured to use either UDP or TCP for GPRS reporting depending on device firmware and user settings. For integration with Plaspy, configure the device to point to the Plaspy server and port supplied below.

  • Plaspy server domain for device reporting is d.plaspy.com
  • Plaspy server IP address is 54.85.159.138
  • The port used by Plaspy for all devices is 8888
  • The device may be configured to use UDP or TCP on port 8888 depending on device support and configuration
  • All devices in Plaspy use the same port which makes bulk configuration and provisioning easier

Protocol Compatibility Notes​

  • The TL-216 is compatible with Plaspy when the device is configured to report to the Plaspy endpoint via GPRS; SMS remains useful for direct phone alerts
  • Firmware version differences can affect which transport modes (UDP or TCP) are available and how certain status fields are reported
  • Hardware revisions or regional device variants may change available features such as reporting intervals, sleep modes, or I O reporting
  • Manufacturer configuration commands and default APN settings must be validated before pointing the device to the Plaspy endpoint
  • Network coverage and SIM configuration affect whether the device stores data locally during outages and forwards on reconnect
  • Always validate compatibility against the device user guide and current manufacturer documentation prior to mass deployment

Why Protocol Understanding Matters​

Understanding the TL-216 communication protocol and how it interacts with Plaspy helps ensure reliable device setup, accurate location reporting, and smooth troubleshooting when devices are in the field.

  • Makes initial provisioning and APN configuration faster and more predictable
  • Helps diagnose connectivity issues by separating transport, network, and device configuration problems
  • Enables appropriate selection of reporting interval and power management settings for expected battery life
  • Improves handling of geofence and low battery alerts by confirming how and when the device sends those events
  • Assists operations teams in planning for data continuity when GSM coverage is intermittent

Why Use Plaspy with This Protocol​

Using the GOTOP TL-216 with Plaspy provides organizations with a simple way to collect and visualize mobile asset location, status, and alerts through a centralized platform. Plaspy translates incoming reports from devices that use GPRS reporting into usable tracking records, allowing fleet managers and security teams to monitor movement, receive geofence notifications, and review historical position logs.
