I've paired, re-paired, tried all sorts of things. I cannot seem to get it to lock or unlock -- actually nothing works. 1 out of about 100 attempts actually worked, but when I tried to increase the PIN length I was never able to get it to work again -- despite numerous un-pairing and factory resets. I updated to R070 (and the beta prior to it) and it seems to be the same -- state is incorrect and am unable to lock/unlock, I haven't tried a factory reset on the lock yet. Some other people have gotten lock/unlock functionality to work, am I missing something?
