*
* Service: org.bluez
* Interface: org.bluez.GattCharacteristic1
*
* Object path:
* [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX/serviceXX/charYYYY
*
* Supported properties:
*
* string UUID [read-only]
*
* 128-bit characteristic UUID.
*
* object Service [read-only]
*
* Object path of the GATT service the characteristic
* belongs to.
*
* array{byte} Value [read-only, optional]
*
* The cached value of the characteristic. This property
* gets updated only after a successful read request and
* when a notification or indication is received, upon
* which a PropertiesChanged signal will be emitted.
*
* boolean WriteAcquired [read-only, optional]
*
* True, if this characteristic has been acquired by any
* client using AcquireWrite.
*
* For client properties is ommited in case
* 'write-without-response' flag is not set.
*
* For server the presence of this property indicates
* that AcquireWrite is supported.
*
* boolean NotifyAcquired [read-only, optional]
*
* True, if this characteristic has been acquired by any
* client using AcquireNotify.
*
* For client this properties is ommited in case 'notify'
* flag is not set.
*
* For server the presence of this property indicates
* that AcquireNotify is supported.
*
* boolean Notifying [read-only, optional]
*
* True, if notifications or indications on this
* characteristic are currently enabled.
*
* array{string} Flags [read-only]
*
* Defines how the characteristic value can be used. See
* Core spec "Table 3.5: Characteristic Properties bit
* field", and "Table 3.8: Characteristic Extended
* Properties bit field". Allowed values:
*
* "broadcast"
* "read"
* "write-without-response"
* "write"
* "notify"
* "indicate"
* "authenticated-signed-writes"
* "reliable-write"

* "encrypt-write"
* "encrypt-authenticated-read"
* "encrypt-authenticated-write"
