LightBlue can connect you to all of your devices that use Bluetooth Low Energy (also known as Bluetooth Smart, or Bluetooth Light). With LightBlue, you can scan, connect to and browse any nearby BLE device. Full support of read, write, and notify is included to ease BLE firmware development efforts. You can also view the signal strength (RSSI) in real time to get an idea of how close you are to the BLE device, handy for finding lost Fitbits or other BLE devices! The log feature allows you to keep track of all significant BLE events that occur while using the app (e.g., device discovery, connection, reading, writing). Use LightBlue to test your new BLE Heart Rate Monitor, temperature sensor, TI CC Keyfob, Nordic uBlue, Panasonic PAN, etc. LightBlue is also ideal for developers wanting to test the firmware of their own BLE peripherals. A note on location access: if your Android device is running Android M (.) and above, you'll need to grant the app fine location access in order for the OS to surface BLE scan results to the app. This is an Android SDK requirementwe do not use your location for anything, not even while the app is in the foreground.
