JL_BluetoothManager方式

//Step0: 获取JL_BluetoothManager对象
JL_BluetoothManager manager = JL_BluetoothManager.getInstance(context);
//Step1: 获取设备信息
final BluetoothDevice device = manager.getConnectedDevice();
DeviceInfo deviceInfo = manager.getDeviceInfo(device);
//Step2: 查询是否支持设备双连功能

RCSPController方式

//获取RCSPController对象
final RCSPController controller = RCSPController.getInstance();
//查询是否支持设备双连功能
final BluetoothDevice device = controller.getUsingDevice();
boolean isSupportDoubleConnection = controller.isSupportDoubleConnection(device);

Note

设备必须支持【设备双连】功能才能使用

JL_BluetoothManager方式

function : AttrAndFunCode.SYS_INFO_FUNCTION_PUBLIC – 公共属性

mask : – 设备双连状态 * 0x00000001 << AttrAndFunCode.SYS_INFO_ATTR_DOUBLE_CONNECT

命令构造

CommandBase getDoubleConnectionStateCmd = CommandBuilder.buildGetSysInfoCmd(AttrAndFunCode.SYS_INFO_FUNCTION_PUBLIC,
            0x00000001 << AttrAndFunCode.SYS_INFO_ATTR_DOUBLE_CONNECT);
