Couple of issue here:

I don't really like the way this makes the create_paired_device function
quite long. Could you maybe refactor the if (!device) branch into a
separate function?

Includes should be the first thing after the copyright/license comments
in the file. However, to keep a clear visibility of potential circular
dependencies Marcel has requested this kind of inclusion of an internal
header file from within an internal header file to be avoided. Instead
make sure you include btio.h from early enough in the respective .c
file. You could also reconsider if you really need BtIOSecLevel here.
Maybe a "gboolean secure" flag would be enough?

Same here.
I'm feeling a little bit ambivalent about your additions to
glib-helper.c. It never had a clearly defined scope and I had been
hoping to get rid of it completely. However now it seems you guys are
constantly adding new stuff there. Is it really so that you can't find a
more specific location for these functions? Could you describe in one or
two sentences the purpose and scope that you think the glib-helper.c
functions have?
