Bluetooth tethering is a manual setting feature, you have to enable it anytime you want to use it and it will be disconnected often, including rebooting the device or disabling bluetooth.

Forget enabling bluetooth tethering on your mobile phone anymore, with this application you just have to specify which devices will be allowed to use it and automatically every time they get connected to your mobile phone, bluetooth tethering is enabled and disabled when disconnected.

I developed this application initially thinking about my car, whenever I needed to use the internet connection, tethering was disabled in the phone and could not activate it while driving.

This app can be used for activating bluetooth tethering with any other devices, not just cars, including tablets and other mobile phones, just use it if you need to activate bluetooth tethering everytime you want to use it.
