[App Overview]
This app is a professional tool that turns your Android device into a high-precision "external GPS receiver". It converts location data from your device's GPS sensor into the GNSS standard NMEA format and sends it in real-time to external devices via Bluetooth (SPP).

The latest version now supports the highly requested "Background Operation" and "Multi-Connection for up to 3 devices".
This transforms your smartphone into a powerful "GPS bridge" or "GPS tethering" app, sharing location data instead of a network connection. Keep your phone in your pocket while simultaneously sharing GPS data with multiple PCs or tablets.
Ideal for demanding field tasks: car navigation testing, surveying assistance, drone operations, and IoT data feeds.

[Key Features]

High-Precision NMEA Output: Generates versatile NMEA sentences (latitude, longitude, altitude).

Bluetooth Multi-Connection: Connect and bridge GPS data to up to 3 devices simultaneously.

Background Operation (Foreground Service): Stable data transmission continues even with the screen off or while using other apps. (*Requires in-app time charge for operation).

Live Dashboard: Pro-grade UI to monitor Bluetooth server status and NMEA data streams in real-time.

[Use Cases]

Tether GPS to Wi-Fi-only tablets to reuse them as large-screen car navigators.

Real-time location input for PC mapping software and log analyzers.

Multi-device location tracking test environments.

[How to Use]

Pair your smartphone with target devices (PC, tablet, etc.) via Bluetooth in advance.

Launch this app and grant the required permissions (Location, Bluetooth, etc.).

Press the "START" button for the Bluetooth channels (up to 3) on the control panel to enter standby mode.

When the receiving device attempts to connect to this app, NMEA data transmission begins.

The remaining time for background operation can be charged (extended) by watching video ads within the app.

[Important Notes]

Background Stability (Important): Android's power-saving features may force-close the app when the screen is off or in the background. To ensure stable continuous operation, please change the battery optimization (battery usage) setting for this app to "Unrestricted" in your device settings.

Permissions: Due to system specifications, permissions (notifications, etc.) are strictly required for accurate location acquisition, Bluetooth communication, and background operation.

Battery Consumption: Continuous background use of GPS and Bluetooth may drain the battery faster. Connecting to a power source during long-term use is recommended.

Operating Time Charge: There is a time limit for continuous background operation. We use a system where you can add operating time by watching video ads.

[Privacy and Security]

Data Protection: Acquired location data is used exclusively for transmission to your authorized, Bluetooth-paired devices. It is never sent to external servers via the internet, nor is it collected or saved by the developer.
