BLE Smart – Bluetooth Scanner

BT Sniffer for Low Energy Scan

BLE Smart is the Swiss Army Knife of BLE Scanner apps used by technology enthusiasts, developers and InfoSec specialists to find, explore and debug devices with Bluetooth Low Energy (BLE, Bluetooth LE, Bluetooth 4.0, Bluetooth 5.0 or Bluetooth Smart).

Available on the App Store

/* your app evolved */

Now available: Version 2.1


BLE Smart includes a high performance scanning algorithm (tweaked for speed), while keeping energy efficiency features in mind – such as the new DarkMode interface that follows the power pattens of OLED technology.

Enjoy a cohesive, intuitive and easy to use interface with beautiful visual widgets – such as the combined indicator to view the Received Signal Strength Indication (RSSI), Proximity, Favourite Status, and Discovered Services count. Functionality such as Favourites, Filters, Sort and Configuration are all in easy reach.

Scan for all BLE devices, refine your search to just your favourites, or use Filter & Sort options.

Operating in a noisy wireless environment?

De-clutter your BLE scan:

  • Use filters such as [RSSI is weaker than] to block unwanted devices.
  • Interested only in your Favourites? In the Scan browser click into your Favourites to enjoy the same scan functionality without all the noise. Nice!

Browse the Advertisement Data, and detect if it changes. If available, BLE Smart will lookup the Bluetooth SIG Company Identifier to provide you the Company and unique number.

How do I explore my Bluetooth device?

  • Connect to BLE Peripheral devices that allow it. BLE Smart will auto-magically populate the Services (White), Characteristics (Blue), and other information it finds.
  • If a GATT Service, or GATT Characteristic is recognised from the Bluetooth specification it will populate its name for you. Custom designed Services and Characteristics will populate their UUID.
  • Drill down into GATT Characteristics to view individual VALUE FIELDS. A LARGE amount of development time has been invested to where possible, derive the field values coming off your device. Some Characteristics contain a lot, others only one.
  • Select text to COPY + PASTE, or SHARE.
  • Change Characteristic Values formats.
  • Receive or Stop Notifications.

You can use these helpful features to test and debug your own development project.

Example GATT Characteristic:
Date Time

Value Fields:
Year, Month, Day, Hours, Minutes, Seconds

How do I find my Bluetooth Device?

A popular use case for a BLE scanner program is to locate a lost BLE device, or BLE tag.

As long as your device still has some battery life, was turned on when you lost it, and is still transmitting – the odds are pretty good that you will still be able to find it.

Walls, metal objects and low batteries can affect range & signal strength. If your building is more than one level – your device may be above, or below you!

  • Turn off any Scan filters that will block your device!
  • Eyeball your device in the Scan Browser. Drill down into the Peripheral Screen.
  • Time for a game of “Your getting Hotter & Colder”! Use the RSSI value to gauge the BLE Peripheral proximity. The proximity indicator will transition from Red(Unknown), Yellow(Far), Light Green(Near), Dark Green(Immediate).

Congratulations! You found your BLE device.

A BLE Logger will log Bluetooth related events for you. Select particular events to COPY + PASTE, or share the entire log.
