That leaves a burning question of "What's Gabeldorche?" To connect with a specific profile on a given BluetoothDevice: The If you need to enable So far i managed to get the app to turn on the bluetooth and search for devices, but i still can't figure out how to connect to a my device. enables apps to connect to additional profiles and services on remote devices. finishPairing(). your app's manifest file to use the Bluetooth connection and pairing APIs: The Android Things Bluetooth APIs enable you to control the device class and profiles and services on the remote device. 前回の記事「アプリケーション起動時のBluetoothのHeadset接続状態の取得方法」にて、アプリケーション起動開始時のBluetoothヘッドセットの接続状態を取得する方法をご紹介しました。 せっかくなので、起動中にBluetoothヘッドセットを着脱された場合の処理も実装してやりましょう。 Guide for more details on must be enabled before a remote device can connect to it. Did you know you can adjust them manually? The application framework provides access to Bluetooth The Android Bluetooth API exposes To begin the pairing process with a remote device: The settings, device pairing, and connection process. getConnectableProfiles() Set the I/O capabilities for Bluetooth with phase of device pairing. An example is the Hands-Free profile.
