abstract member Connect : Android.Bluetooth.BluetoothDevice * Android.AccessibilityServices.IBrailleDisplayController.IBrailleDisplayCallback -> unit

Parameters

bluetoothDevice: BluetoothDevice

The Braille display device. This value cannot be null.

callback: IBrailleDisplayController.IBrailleDisplayCallback

Callbacks used to provide connection results. This value cannot be null.

Attributes: RegisterAttribute RequiresPermissionAttribute

Remarks

Connects to the requested bluetooth Braille display using the Braille display HID standard (usage page 0x41).

If successful then the HID report descriptor will be provided to BrailleDisplayCallback.onConnected and the Braille display will start sending incoming input bytes to BrailleDisplayCallback.onInput. If there is an error in reading input then the system will disconnect the Braille display.

Note that the callbacks will be executed on the main thread using AccessibilityService.getMainExecutor(). To specify the execution thread, use connect(BluetoothDevice,Executor,BrailleDisplayCallback). Requires Manifest.permission.BLUETOOTH_CONNECT
