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"
=E2=94=94=E2=94=80/org
  =E2=94=94=E2=94=80/org/bluez
    =E2=94=94=E2=94=80/org/bluez/example
      =E2=94=9C=E2=94=80/org/bluez/example/service0
      =E2=94=82 =E2=94=9C=E2=94=80/org/bluez/example/service0/char0
      =E2=94=82 =E2=94=9C=E2=94=80/org/bluez/example/service0/char1
      =E2=94=82 =E2=94=94=E2=94=80/org/bluez/example/service0/char2
      =E2=94=9C=E2=94=80/org/bluez/example/service1
      =E2=94=82 =E2=94=94=E2=94=80/org/bluez/example/service1/char0
      =E2=94=94=E2=94=80/org/bluez/example/service2
        =E2=94=9C=E2=94=80/org/bluez/example/service2/char0
        =E2=94=82 =E2=94=9C=E2=94=80/org/bluez/example/service2/char0/desc0
        =E2=94=82 =E2=94=94=E2=94=80/org/bluez/example/service2/char0/desc1
        =E2=94=9C=E2=94=80/org/bluez/example/service2/char1
        =E2=94=82 =E2=94=9C=E2=94=80/org/bluez/example/service2/char1/desc2
        =E2=94=82 =E2=94=94=E2=94=80/org/bluez/example/service2/char1/desc3
        =E2=94=94=E2=94=80/org/bluez/example/service2/char2
          =E2=94=9C=E2=94=80/org/bluez/example/service2/char2/desc2
          =E2=94=94=E2=94=80/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"
=E2=94=94=E2=94=80/org
  =E2=94=94=E2=94=80/org/bluez
    =E2=94=9C=E2=94=80/org/bluez/hci0
    =E2=94=82 =E2=94=94=E2=94=80/org/bluez/hci0/dev_E3_AC_D2_F8_EB_B9
    =E2=94=94=E2=94=80/org/bluez/test

Hope that helps.

Regards,
Barry
