Actually, now I'm having a new problem -- my iPhone doesn't seem to be connecting to the Lockitron via bluetooth at all.
In the past, when i walked near the lockitron with the lockitron app opened, the bluetooth indicator on the status line would turn white, but now it is not doing this at all.
When I rebooted my phone and tried to calibrate again, I got the "No connected lock detected". This is not surprising, given the bluetooth indicator is not white as described above.
Does lockitron kick into some type of lower power bluetooth mode or disable it if the lockitron isn't getting enough power? I have the lockitron plugged into the wall using the fake battery technique and a 5V/2Amp usb adapter. Maybe my lockitron isn't getting enough power?
Just speculating at this point.
P.S. Oh, now it's working again. I had my friend pull out his iPhone 6 plus and open the lockitron app -- bluetooth icon came right on. After that, my bluetooth icon started working as well. Very strange.
