蓝牙读取被拦截

[Chilisauce1212]

在基于nordic nrf52832ble5.0蓝牙芯片开发时，通过一项自定义的可读写服务只能有效写入数据，无法读取。后来在<DeviceControlActivity.Java>Line 342发现在进行特征属性判断时将读写分为互斥事件，实现并行判断后可进行读取。

if ((charaProp & BluetoothGattCharacteristic.PROPERTY_WRITE) > 0) {
                    mSpCache.put(WRITE_CHARACTERISTI_UUID_KEY + mDevice.getAddress(), characteristic.getUuid().toString());
                    ((EditText) findViewById(R.id.show_write_characteristic)).setText(characteristic.getUuid().toString());
                    BluetoothDeviceManager.getInstance().bindChannel(mDevice, PropertyType.PROPERTY_WRITE, service.getUuid(), characteristic.getUuid(), null);
                } else if ((charaProp & BluetoothGattCharacteristic.PROPERTY_READ) > 0) {
                    BluetoothDeviceManager.getInstance().bindChannel(mDevice, PropertyType.PROPERTY_READ, service.getUuid(), characteristic.getUuid(), null);
                    BluetoothDeviceManager.getInstance().read(mDevice);
                }
