About this app

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 CC2540 Keyfob, Nordic uBlue, Panasonic PAN1720, etc. LightBlue® is also ideal for developers wanting to test the firmware of their own BLE peripherals.

Key Features:
- Scan for any BLE peripherals
- See basic device info (name, MAC address, RSSI) at a glance
- Browse characteristics and services
- Register for notifications
- Read characteristics
- Write to characteristics in hex or UTF-8 string format
- Thoroughly log BLE events and share them in plain text format

A note on location access: if your Android device is running Android M (6.0) 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 requirement—we do not use your location for anything, not even while the app is in the foreground.

I would rate this thing 5 stars before the recent update. Before I was able to see the user description with the uuid for individual characteristics in the explorer. Now I have to navigate to the correct uuid and go into it to see the characteristic user description. Also, the Hex keyboard does not seem to work right. I can only type in one character at a time, no more. I also can not delete the single character written.

Hi Brad, our latest release 1.9.0 should've fixed this, please give it a try and let us know if you're still running into issues. Our inbox is always open: info@punchthrough.com. Thanks for using LightBlue!

Great, but no notifications? It would be amazing if you could subscribe to a characteristic and then receive in app notifications when the characteristic receives a notification of its own. I think this behavior occurred in the past? But it doesn't happen anymore (Note 20 Ultra). Please go back to doing that!

I had lost a small Bluetooth step counter in my home. I searched the play store and found several apps claiming to be able to locate Bluetooth devices but they were worthless. Finally I found this app. It took about 10 minutes walking in the house to find the step counter. Kudos to the developer of this gem. Thanks!
