Bluetooth Adapter API provides functions for setting up Bluetooth and discovering other devices.

Required Header

#include <bluetooth.h>

Overview

This set of function is used to control a bluetooth adapter. You can also control visibility of the device, its appearance for others (adapter name). In addition, this api is used to discover neighboring bluetooth devices. This process is asynchronous, so it is up to you to build and hold list of devices in the neighborhood

the api does not provide this list. Before starting a device discovery, you can find a device from the connected devices. This functionality is implemented by foreach loop.

Related Features

This API is related with the following features:

http://tizen.org/feature/network.bluetooth

It is recommended to design feature related codes in your application for reliability.

You can check if a device supports the related features for this API by using System Information,thereby controlling the procedure of your application.

To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.

More details on featuring your application can be found from Feature Element.
