LightBlue Explorer - Bluetooth Low Energy

By Punch Through

Open iTunes to buy and download apps.


LightBlue Explorer can connect you to all of your devices that use Bluetooth 4.0 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
- Read Characteristics
- Write to Characteristics in Hex, Oct, Bin, Decimal or Ascii
- Clone peripheral profiles
- Choose from an array of common preconfigured peripheral profiles
- Advertise as a peripheral using custom profiles
- Thoroughly log BLE events

This app will not work on iPhone4, iPhone3GS, iPhone3G or iPod Touches before the 5th generation, or any other iOS device without built-in Bluetooth Low Energy support.

What's New in Version 2.4.0

* Added new feature that allows the user to sort and filter discovered devices by signal strength.
* Fixed alignment of alert that occurs when Bluetooth is turned off.

Latest version has many defects

We use Light blue to test our own BLE device. The previous version worked great but the latest version disconnects immediately after a large data transfer. On the log page we also see duplicate notifications. Initially we thought we had a firmware issue on our device, but when tried with Nordic Semiconductor's app, our BLE device worked perfectly without any disconnections. Upon sniffing the connection using wireshark, we saw that Lightblue initiated the disconnection after the data transfer was completed.
Links on the "about" page are also broken in the latest version. Please bring back the old lightblue version!

Didn't help me find my Fitbit!

I downloaded this app yesterday because I had lost my Fitbit in my hotel room. After tearing apart the hotel room for 45 minutes (knowing I never left and that my Fitbit had to be in there), I downloaded this app to help. It was worthless. Not only is it confusing to understand (there are lots of signals/items listed and you don't know what they mean), but I never got even a semblance of a strong signal from my Fitbit. Even after assistance from the hotel staff (who found my Fitbit), the app still didn't register a signal. I am wearing my Fitbit now and the app barely recognizes the Fitbit signal and it is one inch away from the phone. I am really bummed about this because I thought the app would be nice to have for the future, but it doesn't work. I don't know how others had such a positive experience. It did not work for what I needed, and if you misplace your Fitbit, I doubt it will work for you either.

Oh My, Thank you for a great experience

My son and I went for a 7-mile ride Saturday morning on two lane roads in our neighborhood. He is in the 6th grade and we recently got new trek hybrid bikes. We stopped at about 3 miles for water and I realized my Fitbit flex had popped out of my shoe strings where I keep it when biking. Gads. We immediately turned around, rode on the wrong side of the bike, and looked for the flex for 3 miles :-( We went back home and then I immediately decided to walk up and back the three miles to find the flex. Man, what a guy will do for $80. I did that walk and didn't find the flex. Bummer. I am thinking, 6 miles on bike and 6 miles walking not logged on my Fitbit. Later that afternoon, I searched for "I lost my Fitbit" and found several references to blue tooth apps that help locate devices. I downloaded LightBlue and off my son and I were in the SUV at 5 MPH searching. We say tons of hits on Bluetooth devices. I wasn't sure how to use the app. We tried to connect to the no name apps but most of the time it failed connection. We did find several TVs and a ton of Apple TVs. We stopped occasionally but did not find the flex. Now it is Sunday afternoon and my sweet son said 'Dad, I will ask Santa to get you a new Fitbit on my list.' Precious cool kid. Now I am thinking, the flex was fully charged, and, I read about the guy using the app in a store. Maybe we were moving too fast? I had my wife drop me off the end of the route, and I walked back, with a USB charger and the phone in front of me so I could catch the various devices recognized. Wow, when walking, I saw a ton more devices. Then pow, I saw a Surge. Was that a Fitbit surge? I think so. Now I am thinking with enough time and device detection; the app will display the name of the device. I walked back 2.5 miles. The sun was going down. To my shock, I see Flex show up. Immediately I thought I picked up a flex from a house. But why isn't it my Flex? I walked more and refreshed the app, and it disappeared. I walked to the other side of the road, then back another 50 feet, waited and tried again. Boom, there is a Flex at -102 signals, then 90 something, then 80, then 70, 69 as I walked. Then the signal started going up. Wala Wala. I think I am close. I zeroed in on 69 power. Bent over and started searching about 2 feet of grassy area on the side of the road, in about a 5-foot area. After a few searches bent over I say something. Man, my Fitbit. I found the darn Fitbit flex in a 3-mile path. Bikes and cars didn't work, but walking with the app did. Congrats on a nice utility.
