Bluetooth OOB (Out of Band) API provides functions for exchanging some information used in the pairing process.

Required Header

#include <bluetooth.h>

Overview

This set of functions is used for exchanging the hash key and randomizer. This API uses an external means of communication, such as near-field communication (NFC) to exchange some information used in the pairing process.

Related Features

This API is related with the following features:

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

It is recommended to use features in your application for reliability.

You can check if a device supports the related features for this API by using System Information, and control your application's actions accordingly.

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.
