Delayed Lock Bluetooth Plugin (de.j4velin.delayedlock.plugins.bt2) on Google Play
This is a plugin which automatically disables the lockscreen while your device is connected to a specific Bluetooth device (for example Bluetooth headset) so you don't need to enter your PIN/password or pattern code while your device is near you (or at least near your headset).Does not work with Bluetooth Low-Energy devices!This is just a plugin and requires the 'Delayed Lock' app version 2.0.8 or newer to run!!
