如何阅读BluetoothGattCharacteristic属性如特征Readable, Writable or Notifiable.

    /**
     * @return Returns <b>true</b> if property is writable
     */
    public static boolean isCharacteristicWritable(BluetoothGattCharacteristic pChar) {
        return (pChar.getProperties() & (BluetoothGattCharacteristic.PROPERTY_WRITE | BluetoothGattCharacteristic.PROPERTY_WRITE_NO_RESPONSE)) != 0;
    }

    /**
     * @return Returns <b>true</b> if property is Readable
     */
    public static boolean isCharacteristicReadable(BluetoothGattCharacteristic pChar) {
        return ((pChar.getProperties() & BluetoothGattCharacteristic.PROPERTY_READ) != 0);
    }

    /**
     * @return Returns <b>true</b> if property is supports notification
     */
    public boolean isCharacteristicNotifiable(BluetoothGattCharacteristic pChar) {
        return (pChar.getProperties() & BluetoothGattCharacteristic.PROPERTY_NOTIFY) != 0;
    }
