Seems like on PR1.2 you won't be able to connect (even manually) after the connection has been closed by AutoDisconnect, but only the first time you try. If you try one more time - the device connects successfully.
Not sure if this is 100% reproducible, but I'm facing the issue quite often, and I never faced it before I installed AutoDisconnect.

Otherwise, great app! I see major progress since v0.2 and I really like it.
