BLE out of band mgmt over dbus?

BLE out of band mgmt over dbus?

[Ryan Nowakowski]

Hello bluez devs!

It seems like the mgmt API, particularly the out of band management[1]
isn't available via dbus.  Is there a particular reason that the mgmt
stuff isn't exposed via dbus?

Thanks!

We have a plugin for neard, which is probably outdated by now, to do
OOB, not sure if that is your use case though.

We've looked at the neard plugin and it doesn't quiet fit our
situation.  It looks like some other mgmt commands are already available via
dbus(discovery, etc).  I'm thinking about writing a patch that would
add the OOB mgmt commands to dbus.  Is this a terrible idea?

Perhaps you are referring to ConnectDevice:

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/adapter-api.txt#n154

We could perhaps introduce an optional property for the application to
include the OOB data, but that should be validated by connecting and
attempting to encrypt, if that fails the OOB should be discarded.
