Good examples of BLE-enabled devices are fitness trackers, iBeacons, blood pressure monitors, and industrial sensors. This alteration to the original Bluetooth specification has allowed manufacturers to create a plethora of small, wearable devices that can run for up to several years on a small battery. BLE remains in sleep mode at all times except when participating in a data exchange, which reduces overall energy consumption. These devices make use of Bluetooth Classic technology.īluetooth Low Energy, on the other hand, is used for periodic transmission of smaller data packages. Think of wireless speakers, keyboards, and headsets. It’s used for continuous transmission of vast amounts of data across relatively short distances. There are two different types of Bluetooth technology: Bluetooth Classic and Bluetooth Low Energy.īluetooth Classic is the technology you’ve probably interacted with the most. Let’s start by explaining the basics of Bluetooth Low Energy technology. We want to shine some light on how attackers can exploit your connected devices and how you can protect them.

If you want to create a Bluetooth-connected device, chances are you’ve considered using Bluetooth Low Energy (BLE) and have heard about BLE security issues.
