A development tool for Bluetooth devices
Explore Bluetooth Low Energy devices in range, test their behavior, and debug your integration before writing application code. Universal BLE is free and open source, with apps for iOS and Android and a web explorer.
Discover and inspect
Scan for nearby devices, inspect advertisements and signal strength, and filter results by name, service UUID, or manufacturer data. Connect to a device to explore its services, characteristics, and descriptors.
Test and debug
Read and write characteristic values, subscribe to notifications, and follow incoming data in the operation logs. Copy a device’s GATT layout or logs to document its behavior and investigate issues during development.
Built on Universal BLE
The app uses our Universal BLE Flutter library, bringing the same Bluetooth API used in our professional products to a practical developer tool. Explore the app source code to see how it works or contribute.
The web explorer requires a browser with Web Bluetooth support. Available operations depend on your device and platform.
