Description
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.
Recent changes: Added a new feature to advertise a specific service of a virtual device. Added support for local "Nicknames" for a Characteristic/Service. Expanded support for filters by adding more categories. Minor bug fixes

This BLE app has the clearest interface in my experience, and helped me poke around some devices.

I found the microchip they planted in my toe with this! Thank god I thought I was insane

Works pretty good - found a govee BLE humidity 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!

Found my ear buds! I tried using the Galaxy Wear App to locate one of my two ear buds but the App would not make the bud chirp to sound off. A Reddit user recommended using the Light Blue app to triangulate the Bluetooth power of the bud by walking around my home and looking at the Light Blue app for signal loss or gain. I highly recommend this app.

The application doesn't work well with iPad A16, if something needs LE privacy it's not able to connect to the services nor able to initiate bonding.

On the website it said you could find your Bluetooth device even if it was turned off Didn't work

From the value write page, you can not access the backspace 0 or done buttons because the screen is set too low. Those buttons are behind the cancel, homepage, and back. Buttons.
