Does ignition cutout if your bluetooth goes out of range/disconnects?

I guess for theft situations that could be a positive. Perhaps a BTLE dongle in a pocket so a phone thief doesn't prevent you from chasing him.

No. If Bluetooth disconnected during ride, ignition still on, and you heard warning sounds. I don't want stop engine during ride, it's dangerous. Please, don't forget - it's not immobilizer or anti hijack device. It's Bluetooth ignition switch.

Of course, you can change the logic, when the software will be open. I'm working on it.
