LightBlue® — Bluetooth LE

Punch Through Design

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.

Ratings and reviews

Still haven't had a use case to test out the functionality, so that's for later. I know it's called "Light"Blue but dark mode interface would be nice, for accessibility. If it's an option already, I can't find it.

Lost my huawei Freebuds 2 days ago. Couldn't figure out where to find them, at the office at my house or in the car. Had almost written them off when I searched the internet as a last ditch effort, installed lightblue and voila... Within 5 minutes of roaming about in the house I found them... Great app.. 5 stars all the way... There's one caveat though... Instead of just the Mac address it should display the device type or name as well, would be more helpful.

Hangs routinely, so I had to stop and restart it routinely. Two other programs were more reliable. I did learn from using this app that apparently most BT devices can't be identified even by manufacturer, so at least I got one thing out of it. Just not my device. But that's not their fault.
