Locating /org/bluez/example/service from example-gatt-server

Locating /org/bluez/example/service from example-gatt-server

[Alan Martinovic]

Hi,
in the example-gatt-server which is provided in the
sources there is a reference to the dbus object
`/org/bluez/example/service`.

When that example gets run successfully under what
 "unique connection name" does that object end up living?

It doesn't exist under org.bluez

~$ busctl --list tree org.bluez
/
/org
/org/bluez
/org/bluez/hci0

Be Well,
Alan

Hi Alan,

If a do a "busctl list" before and after starting the
"example-gatt-server" I can see that there is a new service started.
The way the example is coded it doesn't get given a nice service name
but I can see it is called (in my case) ":1.20"

I can now see the tree of services created.

$ busctl tree ":1.20"
└─/org
  └─/org/bluez
    └─/org/bluez/example
      ├─/org/bluez/example/service0
      │ ├─/org/bluez/example/service0/char0
      │ ├─/org/bluez/example/service0/char1
      │ └─/org/bluez/example/service0/char2
      ├─/org/bluez/example/service1
      │ └─/org/bluez/example/service1/char0
      └─/org/bluez/example/service2
        ├─/org/bluez/example/service2/char0
        │ ├─/org/bluez/example/service2/char0/desc0
        │ └─/org/bluez/example/service2/char0/desc1
        ├─/org/bluez/example/service2/char1
        │ ├─/org/bluez/example/service2/char1/desc2
        │ └─/org/bluez/example/service2/char1/desc3
        └─/org/bluez/example/service2/char2
          ├─/org/bluez/example/service2/char2/desc2
          └─/org/bluez/example/service2/char2/desc3

While the object path is the same as "org.bluez", they are stored
under a different service. So if I do "org.bluez" I can see they are
not there:
$ busctl tree "org.bluez"
└─/org
  └─/org/bluez
    ├─/org/bluez/hci0
    │ └─/org/bluez/hci0/dev_E3_AC_D2_F8_EB_B9
    └─/org/bluez/test

Hope that helps.

Regards,
Barry
