App Description

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.

Key features:
- Scan and discover Bluetooth peripherals in the vicinity
- See basic device info (UUID, RSSI)
- Browse services and characteristics
- Register for notifications and indications
- Send data from notifications and indications to AWS IoT or Adafruit IO via our Cloud Connect feature
- Read values from 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 and share BLE events
- Custom UI and extended support for connecting to Microchip AVR-BLE and PIC-BLE development boards

Found my Oura ring

I lost my Oura ring and tried many blue tooth location apps: BLE Hero, Bluetooth BLE Device Finder, BLE Scanner, Find My Lost Bluetooth Device, Wunderfind, and Find My Device, but none could find it. After a neighbor eventually found the ring, I tried all of these apps next to the ring, and they still couldn’t detect it. I assume it’s because the ring emits a very low powered bluetooth signal. However, LightBlue can successfully find the ring, up to 10 feet away in my tests. I’d give five stars if the app had the ability to manual name (and remember) unnamed devices.

I recently dropped my right Skullcandy earbud into my yard at night and this allowed me to track the signal to find it. Your neighbors might think you are nuts crawling in the yard with your phone, but you can find a matte black needle in a hay stack at night with this app.

I tried to find my fitbit and when I joined the app I enabled bluetooth and it kept telling me I need to enable the bluetooth to use it which I did.

Simple, reliable BLE debugging

This app has the same simplicity as the LightBlue Bean did - I love how Punchthrough makes this stuff simpler to use than the *massive* spec would imply.I only have one quibble: the service count in the peripherals list only counts services that are in the official 16-bit short code set. As an example, a device that implements a Battery Service and a custom service will be listed as having one service in the list.Making custom services more apparent in the UI can help a lot with application development. Most BLE devices implement custom services if they also use a device-specific app.

doesn't work on "odd brand" devices

I don't know how this app has a bunch of great reviews. My wireless headphone fell out at my grandmothers and I downloaded this app to search for it. Didn't work. Nothing came up.
