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.

Works pretty good - found a govee BLE humidistat straight away once I thought to filter based on signal strength. Enough raw data for me to start directly accessing device w Home Assistant. Handy.. thanks devs!

Absolutely useless. Can't even detect my bluetooth headphones literally next to my phone. Their "learn" button is just articles upon articles of advertisement on what the app supposedly does and the necessity of it, but no clear "how to use the damn thing".
