The Bluetooth Special Interest Group (SIG) has just released version 6.0 of the Bluetooth standard. The last major version, Bluetooth 5, launched in 2016, although the Bluetooth SIG updated this to version 5.4 in 2023. Bluetooth 6 primarily focuses on increased efficiency and reliability, allowing more IoT devices to use it for communication.
Bluetooth 6 implements two new features that help it reduce power consumption — Decision-Based Advertising Filtering and Monitoring Advertisers. These features help Bluetooth devices reduce power consumption and increase efficiency by ensuring they only scan for data packets when they receive data on their primary channel relevant to their application. Furthermore, Bluetooth 6 now tells devices when another device they want to connect to moves out of range so they can cancel their attempt and save energy.
