Bluetooth is a widely used wireless communication technology standard managed by the Bluetooth Special Interest Group (SIG). The Bluetooth Low Energy (LE) protocol is regarded as a different protocol from Bluetooth Classic, and is designed to transmit smaller amounts of data at relatively lower data rates, thus providing lower power consumption.
In this lesson, we will start by introducing Bluetooth LE and its stack layers. Then we will briefly discuss how Bluetooth LE connections take place, covering concepts like advertising and scanning. Subsequently, we will present possible network topologies and Physical Layer (PHY) modes.
In the exercise section, we will practice flashing a Bluetooth LE sample to your Nordic device and using Bluetooth LE to read buttons and control LEDs.
