Hi all,

as the bluez package maintainer for openSUSE, I'm trying to transition
the package to build without "--enable-deprecated".

Now the users started asking me what to use as a replacement for the
deprecated tools.

For many of the tools, the answer is "just use bluetoothctl and let
bluetoothd handle things" (hciconfig, hcitool, sdptool)

But for rfcomm, I have not been able to find a suitable replacement.

All the other implementations of rfcomm services that I could find in a
quick search (some python modules, blueman) just basically reimplement
the functionality of rfcomm (socket(), bind(), connect(), ioctl()...),
some of them in really odd / crazy ways, which is probably not the way
to go...

So is there a way to set up a rfcomm device via bluetoothctl? I could
not find one, but maybe I did not look hard enough?

If not, could we please un-deprecate rfcomm, because having everyone out
there reinvent the functionality in crazy ways probably is not a good idea.

Or should I just continue to build the package with --enable-deprecated?
But that will ship tools with known unfixed security issues (hcidump).

Have fun,

	Stefan
