LightBlue® can connect you to all of your devices that use Bluetooth Low Energy (also known as Bluetooth Smart, or Bluetooth Light).
LightBlue® has two modes, central and peripheral. In central mode, you can scan for and connect to all BLE devices around you. Once connected, you have a detailed view of all the device's profiles, from which you can read and write to characteristics and subscribe to notifications.
To enter BLE peripheral mode, navigate to the "Virtual Devices" tab and tap on the "+" icon to create a virtual device. When the blue checkmark is checked for a device, your iOS device is advertising as that particular BLE peripheral. LightBlue® allows you to customize the services and characteristics of any virtual peripheral profile. You can also clone any peripheral you connect to in central mode and save that profile to your list of virtual peripherals—simply connect to a device and tap on the "Clone" button on the top right of the screen.
Full support of read, write, and notify is included. You can view the signal strength (RSSI) to get an idea of how close you are to the peripheral.
The log tab allows you to keep track of all significant BLE events that occur while using the app (e.g., device discovery, connection, reading, writing), and you can share the content of the log.
Use LightBlue® to test your new BLE Heart Rate Monitor, temperature sensor, Microchip AVR-BLE and PIC-BLE development boards, TI CC2540 Keyfob, Nordic uBlue, Panasonic PAN1720, etc. LightBlue® is also ideal for developers wanting to test the firmware of their own BLE peripherals.

Found my Fitbit One
Lost my Fitbit One on a very long autumn (leafy) park walk. After 4 days I was able to do the same walk again with LightBlue running on my phone. After about 1.5 miles of walking at our normal fast pace ‘One’ popped up in the list of Peripherals Nearby and (astonished) we started the search, kicking through the leaves and using the app’s signal strength indicator to home in on the device. It’s not pin-point accurate so it took a while to narrow down the search area, but we did and unbelievably we found the One, dirty and hidden in leaves. Great app that worked for me.
Found my Fitbit!
Very good app! Fitbit was lost in a field. It took about 1h to find it but I got there. The measures were not as precise as I could have hoped though. At 40 meters I got 0 or 1 bar out of 5. And it’s only when I was at 3m that I got 2 bars and then it went quickly to 5 bars out of 5. Consequence is that you walk around in various directions and you don’t seem to get any closer or further. So there might be something to improve here. But I don’t complain, I’m amazed that it could track it from 40m away in the first place! Would recommend the app for sure!
Found my Fitbit
Lost my Fitbit one 3 days ago. Went to the area I lost it in and opened the Fitbit app. I walked the areas I had been in until the Fitbit started syncing. After a quick look around I still couldn’t locate it so I used this app and wandered around until I got 3 bars indicating my Fitbit was in a trash bin, sure enough when I dug around there it was at the bottom of the bin. Many thanks so glad to have successfully retrieved my Fitbit.
