Where can I read the contents of 'Characteristic User Description (2901)' descriptor? It would be very usefull when exploring services of undocumented BLE devices. Other than that, the app is greap and your blog is awesome! Update: Thanks, now it's even better!:)

Does what it says. I lost my Garmin watch, it fell behind my wardrobe. I'd of never of found it. You just have to move around very slowly with your phone for it to find the Bluetooth signal

I see that there have been problems with reading Characteristic User Descriptions before. I can't get LightBlue to read them now, but it used to work great. I have a recording from April that shows LightBlue naming all of the custom characteristics of my custom service by their Characteristic User Descriptions. It's the only BLE client I've seen that could do this. Now, it only names the first one. And, nothing happens when I click on Characteristic User Description under DESCRIPTORS.

I had lost my fitbit charge 2 and with 3 young kids it might've grown legs. I was able to find it with this app although I wish it was a little more clear of what is needed to do for noobs.

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.

New features

This release fixes a crash caused by attempted interactions with restricted GATT characteristics, which include: FIDO service, LE Audio services, HID service, and the Android TV remote service.

Please write to info+lbxandroid@punchthrough.com if you wish to report any issues with the app. Thank you for using LightBlue®!
