From an API point of view, with some little knowledge of what's going
on, everything needed is around to create for instance multiplayer games
talking to each other over Bluetooth (basically use cases where your app
stays focused and the screen stays on). The only thing that's really
missing is an apparmor Bluetooth policy to allow those things from
confined apps. IMO it's about time to add that tho. I'll see if I can
poke Pat next week about this.

QtBluetooth is currently not included in the image seed, however,
installing libqtconnectivity-dev:armhf in the chroot and shipping
libqbluetooth5 within your click package would do just fine (example
here [1]).

Here for instance is some (very unpolished) code that adds a content hub
plugin for sending files over OBEX push [2] (in the shareplugin dir).
Note that I wrote this during Bluez4 days, so it wont work as is any
more today.

For other use cases, that require keeping a permanent connection to a
device even when the phone's screen is off, indeed currently there is no
defined way forward on how to get that into the official store. At this
point, I guess OpenStore is your best bet. An example for a smartwatch
app in OpenStore can be found here [3].

In any case, I think starting off with OpenStore and moving things over
to the official store as the Bluetooth story shapes up is a viable option.

Hope this helps,
Michael
