Bluetooth Low Energy Communication
Bluetooth Low Energy (formerly known as Bluetooth Smart) is a wireless communication protocol that uses Bluetooth with low-power peripheral devices. These peripheral devices include fitness trackers, health monitors, and personal electronics such as smartwatches or wireless headphones. Bluetooth Low Energy communication support is different from the Bluetooth Communication interface in MATLAB®.
The Bluetooth Low Energy interface is supported on these platforms:
macOS 10.13 High Sierra or later
Windows® 10, version 1709 or later
To connect to peripheral devices that support Bluetooth Low Energy, your computer needs to have a built-in or external Bluetooth 4.0 adapter. After you connect to a device, use MATLAB to read from or write data to it. You can work with both standard and custom services, characteristics, and descriptors.
To learn more about the standards and specifications of Bluetooth Low Energy communication, see Bluetooth SIG.
To simulate, analyze, and test Bluetooth communications systems, see Bluetooth Toolbox.
