一、发送BLE广播 调用蓝牙适配器的getBluetoothLeAdvertiser方法,获得BluetoothLeAdvertiser广播器对象。 广播器的主要方法说明如下: startAdvertising方法表示开始发送BLE广播, stopAdvertising方法表示停止发送BLE广播。 在广播回调对象的onStartSuccess方法中,要给BLE服务端添加服务及其特征值,并开启GATT服务器等待客户端连接。
你可以根据需要更改广告设置和数据。 步骤4:停止广告 在MainActivity的onDestroy()方法中,添加以下代码: if(bluetoothAdapter!=null&&bluetoothAdapter.isEnabled()){bluetoothAdapter.getBluetoothLeAdvertiser().stopAdvertising(advertiseCallback);} 1. 2. 3. 这段代码将在应用程序销毁时停止BLE广告。 步骤5:运行应...

How do you connect to a BLE device? Sometimes the advertising data from a device is all you need. Bluetooth beacons are an example of this. In that case, everything is contained inresult.scanRecordin your scanCallback’s onScanResult override. Your life is simple. ...
With the autoconnect flag set to false the connection will end up with an error if a BLE device is not advertising when the RxBleDevice#establishConnection method is called. From platform to platform timeout after which the error is emitted differs, but in general it is rather tens of ...
