Tizen Native API
3.0
|
Bluetooth Device API provides functions for managing bonds with other devices and searching for supported services.
Required Header
#include <bluetooth.h>
Overview
This set of functions is used to handle the connection with other devices. Connected devices exchange keys needed for encrypted communication, but each connection has to be approved by the latest application user. You can also set authorization of other devices. Authorized devices are connected, and it is connected automatically without the latest user being asked for authorization. In addition, this is used to search for services available on remote devices.
Related Features
This API is related with the following features:
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.
