Description

From the listing uploaded by “appupdater”.

New in latest version:: Added Widget used to toggle service Added "Start ANY app" on Bluetooth connect Added ability to run in foreground which makes it less likely the operating system will shut down the service. Added ability to start YouBlue on boot. Optimized UI Multi-Language Support HIGHLIGHTS (details lower in page):: Action -> Reaction Lost connection to Wifi -> Turn on Bluetooth, check for devices Connected to Bluetooth -> Start an app of your choosing (see settings) ***WANT TO TEST IT?*** (if you're connected to wifi) -if you want a music app to start on Bluetooth connect, be sure to go to settings and select the desired app -it assumes you're disconnected from wifi at startup, so turn on Bluetooth manually before starting the service to see it turn it off after a few seconds -you can also disable wifi after starting the service to simulate a disconnect from wifi. It will turn on Bluetooth. This is a very simple app which uses some logic to determine when/if your Bluetooth adapter needs to be on (Smart Bluetooth Control). If your car supports Bluetooth but you don't make use of it because you don't remember to turn it on, or if you leave Bluetooth on all the time but want to save battery, this app is for you. It's a service which runs in the background and can be toggled on/off in app or via the widget. Once the service is started, it will keep running even if you close the app. To stop it, open the app and click the stop button or tap the widget. DETAILS:: Algorithm: (Completely Customizable) -Wifi Detection- On wifi disconnect, Bluetooth is turned on for 20 seconds. If it connects, it's done. If it doesn't connect it will try again 6 more times in 2 minute increments. (In case your router is far from your car, apartment?) -Bluetooth Detection- On Bluetooth connect, a desired music app will be started if configured from the settings menu.
