Hello,
The Python examples provided in the test directory of the BlueZ
repository use the python-dbus library. Looking at the documentation
of that library it does start by raising concerns and offering
alternatives. I have been looking at some of the alternatives and am
having difficultly getting them to work with BlueZ. I have been
focusing on the org.bluez.LEAdvertisement1 interface.
Looking at the documentation, it says the service, interface and
object details are:
Service org.bluez
Interface org.bluez.LEAdvertisement1
Object path freely definable
I am not being successful at publishing to the org.bluez service. It
is also not where the current examples publish to.
Looking at the GattProfile1 documentation, it has service and object
as application dependant.
Service <application dependent>
Interface org.bluez.GattProfile1
Object path <application dependent>
Should the documentation of Service on LEAdvertisement1 be freely
definable also?
I have created the LEAdvertisement1 interface so that it has an
ObjectManager and is introspectable. When I pass the object to
RegisterAdvertisement on the org.bluez.LEAdvertisingManager1 interface
it accepts it (does not give an error) but does not register the data
and I see no advertisement appear. Is there somewhere I can find a
more detailed description of what needs to be on the
org.bluez.LEAdvertisement1 interface that will work with
RegisterAdvertisement?
For reference, I have put below what I am currently putting on the
org.bluez.LEAdvertisement1 interface.
Thanks,
Barry
