Bluetooth Low Energy (BLE) is a wireless communication technology used for low power devices such as smartphones, wearables and IoT devices. Learn from our audio experts how the Generic Attribute Profile (GATT) and the Generic Access Profile (GAP) work together to allow BLE devices to communicate with each other.
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.
