Hi Claudio,
Thanks for your reply sincerely. In my proposal, there are two properties need to be
extended to org.bluez.GattService1.
One point you have figure out is service type, according to "Includes"
property is not enough to judge the service type.
Another proposal is that maybe one device connect to multiple LE devices , so
under the interface of org.bluezGattService1, it better to expose the object
Device such as object Service exposed under the org.bluez.GattCharacteristic1.
there will be clear GATT Dbus hierarchy and more easier for user to use.
Thanks
Chaojie Gu
