如何连接到配对的BLE设备

所以在得到 Paired Devices ,找到您的设备并按如下方式连接:

BluetoothAdapter bleAdapter = ((BluetoothManager) getSystemService(BLUETOOTH_SERVICE)).getAdapter();
            Set<BluetoothDevice> pairedDevices = bleAdapter.getBondedDevices();
            for(BluetoothDevice d: pairedDevices){
                if(d.getAddress().equals("Your Device MAC")){
                   d.connectGatt(MainActivity.this, true, new BluetoothGattCallback() {
                        @Override
                        public void onConnectionStateChange(BluetoothGatt 
                               gatt, int status, int newState) {
                            super.onConnectionStateChange(gatt, status, newState);
                            switch (newState) {
                                case BluetoothProfile.STATE_CONNECTED:
                                    Log.i("GattCallback", "connected");
                                    gatt.getServices();
                                    break;
                                case BluetoothProfile.STATE_DISCONNECTED:
                                    Log.i("GattCallback", "Disconnected");
                                    break;
                            }
                        }
                    });
                }
            }

实现 Auto Connect 设置 自动连接 变量 true 在里面 device.connectGatt(context, Auto Connect, BluetoothGattCallback); .
