The Google Fast Pair Service, or simply Fast Pair, is Google's proprietary standard for quickly pairing Bluetooth devices when they come in close proximity for the first time using Bluetooth Low Energy (BLE). It was announced in October 2017 and initially designed for connecting audio devices such as speakers, headphones and car kits with the Android operating system. In 2018, Google added support for ChromeOS devices, and in 2019, Google announced that Fast Pair connections could now be synced with other Android devices with the same Google Account. Google has partnered with Bluetooth SoC designers including Qualcomm, Airoha Technology, and BES Technic to add Fast Pair support to their SDKs. In May 2019, Qualcomm announced their Smart Headset Reference Design, Qualcomm QCC5100, QCC3024 and QCC3034 SoC series with support for Fast Pair and Google Assistant. In July 2019, Google announced True Wireless Features (TWF), Find My Device and enhanced Connected Device Details.
