LightBlue® Explorer can connect you to all of your devices that use Bluetooth Low Energy (also known as Bluetooth Smart, or Bluetooth Light).

LightBlue® Explorer 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 use peripheral mode, tap the blue circle next to one of the profiles listed under "Virtual Peripherals." When the blue checkmark appears, your iOS device will begin advertising as that particular BLE peripheral. LightBlue® Explorer allows you to customize the services and characteristics of any virtual peripheral profile. Tap the "+" in the top right corner of the home screen to add new virtual peripherals. You can also clone any peripheral you connect to in central mode and save that profile to your list of virtual peripherals.

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 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® Explorer to test your new BLE Heart Rate Monitor, temperature sensor, TI CC2540 Keyfob, Nordic uBlue, Panasonic PAN1720, etc. LightBlue® Explorer is also ideal for developers wanting to test the firmware of their own BLE peripherals.

Key Features:
- Scan for any peripherals
- Grab basic device info (UUID, RSSI )
- Browse Characteristics and Services
- Register for Notifications and Indications
- Send Data from Notifications and Indications to AWS IoT or Adafruit IO
- Read Characteristics
- Write to Characteristics in Hex, Oct, Bin, Decimal or Ascii
- Clone peripheral profiles

So happy!

This app totally works! I never write reviews BUT had to for this one. I’ve been going nuts looking for my Fitbit for days! I had just bought a cute new band for it! I knew it was in my house because it was syncing with the app. Found this app (after almost paying $6 for a different one) and sure enough, my Fitbit along with my iPad and some various devices with no name came up! I started walking around my house and little blue bars started popping up and down next to the Charge 2. Still couldn’t locate it and gave up last night, still going crazy! Got up this morning and started the app up again and the bars came up again. I finally went out and looked in my car again and all of the bars lit up. Warmer, warmer, and bam, SCORE! I found it. Thank you!

I lost my fitbit and I found it with this even though the battery was SO low! This is free, no need to pay for the other types. You will see a list of Bluetooth devices it finds when you open it. Find the Alta or whatever you are looking for in the list. On the left there are some bars that will turn blue as you get closer - the more bars, the closer you are. I also used my fitbit app and saw which room it synced quickly with. Then I walked around the room and saw where the signal was strongest by number of blue bars. My fitbit had attached itself to a hanger in my closet - had totally given up on it as the battery was dead but gave it one more shot and found it - good luck!

Lost, then found

Lost Fitbit One while doing yard work. Noticed it missing later in the evening. It still synced to my iPhone, so I knew it must be nearby. Within five minutes of opening this app I was guided to check outside, where the One had slipped from my pocket. Mind you, this was in darkness, with only the light from the phone's screen and the app's detection capability. A genuine gem of an app! Tried three, and this one did the job!
