What is BLE, and How Do its Related GAP and GATT Profiles Work? Bluetooth Low Energy (BLE or LE) is a wireless network technology that uses the same frequency bandwidth as classic Bluetooth but with a different modulation strategy. BLE was designed for low energy and low cost and has been expanded for LE Audio. Our engineer explains BLE and its related GAP and GATT profiles.
How Bluetooth is Used for Digital Contact Tracing Digital Contact Tracing and Exposure Notification apps provide a hands-on exploration of Bluetooth Low Energy (BLE) technology, GAP & GATT. Our engineer compares multiple Linux BLE Sniffing Tools including Hcitool, Bluetoothctl, Hcidump and Gatttool.
