Bluetooth Low Energy

Introduction

Low Energy uses the Generic Attribute Profile to support a hierarchy of Read/Write/Notify operations on a set of Characteristics rather than using a constantly open stream like classic Rfcomm connections. Many services are available, both those defined by the Bluetooth SIG and third-parties.

Platforms

Bluetooth Low Energy is supported on Windows 8.1 and later, iOS, macOS, tvOS, Android, Tizen and other platforms. Capabilities vary depending on OS and version. 32feet has a library for Bluetooth LE - InTheHand.BluetoothLE. There are different requirements for ensuring your app has the correct permissions to use Bluetooth depending on the platform. Read more about Bluetooth permissions
