Re: RFC- Having a bluetooth service to handle pairing

Hey there,

Currently the only bluetooth agent available in ubuntu touch is
implemented in system settings. Which means the settings application
need to be open for bluetooth pairing to work.

Is this the same on desktop ( ie. pairing only works when the gnome-bluetooth-settings app is running )?

We received some bugs reports suggesting that the is a need for having
request handled at any time because that's the most robust things to do
and the less confusing for users (ideally known/trusted device would
always be able to auto reconnect, but it seems that in practice sometime
the trusted link is lost and the system need to prompt again, also other
action are done in settings which make the pairing less reliable)

To address this issue we are thinking about moving the auth agent out
from system settings to be a standalone service. We are going to start
working on that but wanted to check first if anyone feeling strongly
against it. The service might lead to a bit more power usage, but it
would only be active if bluetooth is on and things like visibility would
probably be configurable as well.

Has anyone looked at the plugin architecture in Bluez? From a quick look, this appears to be a mechanism to extend the functionality of bluetoothd ( the main Bluez daemon ).

It also appears that Bluez5 includes a plugin called autopair. From a description in the plugin itself:

Plugin to handle automatic pairing of devices with reduced user interaction, including implementing the recommendation of the HID spec for keyboard devices.
