LightBlue® — Bluetooth LE

LightBlue is a versatile mobile application that enables users to connect to and interact with devices using Bluetooth Low Energy (BLE), also known as Bluetooth Smart or Bluetooth Light. With LightBlue, you can effortlessly scan, connect to, and browse any nearby BLE device, making it an essential tool for both casual users and developers working on BLE firmware. The app offers full support for reading, writing, and notifying, simplifying the process of developing and testing BLE devices. Additionally, LightBlue allows you to view the signal strength (RSSI) in real-time, which is particularly useful for locating lost BLE devices such as Fitbits. Key Features: BLE Device Scanning and Connection: Easily scan for and connect to any nearby BLE devices. LightBlue provides a user-friendly interface for browsing and interacting with these devices. Full Read, Write, and Notify Support: LightBlue supports all BLE operations, including reading, writing, and notifying, making it an ideal tool for BLE firmware development and testing. Real-Time Signal Strength (RSSI) Monitoring: Monitor the signal strength of connected BLE devices in real-time. This feature is invaluable for locating devices or understanding the proximity of your BLE peripherals. Logging Feature: Keep track of all significant BLE events, such as device discovery, connection, reading, and writing. This feature is particularly helpful for developers who need to analyze the behavior of their BLE devices. Compatibility with Various BLE Devices: LightBlue can be used to test a wide range of BLE devices, including heart rate monitors, temperature sensors, and development kits like the TI CC Keyfob, Nordic uBlue, and Panasonic PAN. Developer-Friendly: LightBlue is an excellent tool for developers looking to test and debug the firmware of their BLE peripherals. The app provides comprehensive features that simplify the development process. Why Choose LightBlue? LightBlue is an indispensable tool for anyone working with BLE devices, from developers testing firmware to users trying to locate lost peripherals. With its comprehensive feature set, including full read, write, and notify support, real-time RSSI monitoring, and detailed logging, LightBlue makes it easy to connect to and manage BLE devices. Whether you're developing new BLE hardware or just trying to find your lost Fitbit, LightBlue offers the tools you need to get the job done.

Download and Install: Install LightBlue from the Google Play Store or Apple App Store on your smartphone or tablet. Launch the App: Open LightBlue to access the main interface. Grant Location Access: If your device is running Android M (6.0) or above, you'll need to grant fine location access for the app to detect BLE devices. This is required by the Android SDK, but the app does not use your location for any purpose. Scan for BLE Devices: Tap the scan button to begin searching for nearby BLE devices. The app will display a list of detected devices, showing their names and signal strengths (RSSI). Connect to a Device: Select a device from the list to connect. Once connected, you can browse the device's services and characteristics, read data, write values, and set up notifications. Monitor Signal Strength: View the real-time RSSI of connected devices to estimate their proximity. This feature is especially useful for locating lost BLE devices. Use the Logging Feature: Enable the logging feature to record all BLE events, including device discovery, connection status, and data transactions. Review the log to analyze the behavior of your BLE devices or to debug issues. Test and Develop BLE Firmware: LightBlue is perfect for developers testing BLE peripherals. Use the app to perform read, write, and notify operations, and monitor the results in real-time. Disconnect and Rescan: When you're finished, disconnect from the current device and perform another scan if needed to connect to a different BLE device.
