When your device is connected to Android Auto in car, you can see the VAG DPF icon available in the Android Auto app list.
Starting from release 4.45.16 you can start/stop the connection with the OBD adapter directly in Android Auto, without the need to open the Android app.
How to start
You can start the connection either from Android or Android Auto. To start from Android Auto, a bluetooth/wifi adapter must be already selected in the Android app.
Please note that from Android Audo you can start the connection to the ODB adapter, but after that, the date will be read only if the option "Automatically start the data communication after connection" option is selected in the app options (it's selected by default when you install the app).
Notification icon
To guarantee the correct background functionality, the app now works as a service. To avoid the app closing by Android memory management, the app icon in the notification bar must be present. If you remove the notification icon, the app will close just like when you close it normally.
Layout type
Android Auto has 2 layouts that you can choose in the Android app options menu: 1 Tab and 2 Tabs.
- 1 Tab: has only one page with all 12 parameters and you can scroll up/down to see them.
- 2 Tabs: has 2 pages that you can select on top, each page contains 6 parameters only.
Unfortunately, Android Auto layouts for IOT apps are heavily limited, I can only choose between list or grid layout, with few customization options. This is the reason why I can't create a nice graphic layout.
Commands
With 1 Tab layout selected, tapping the first icon will disconnect the OBD adapter.
With 2 Tabs layout selected, tapping the first icon will disconnect the OBD adapter, tapping the third icon will change the tab.
Special icons
- Soot mass icon
This icon becomes red when there is a soot burning in the DPF.
Inside the icon you can see some circles corresponding to the soot inside the filter. The number of circles depends on the soot filling rate: the higher the fill rate, the greater the number of circles.
- Regen duration/status icon
This icon becomes red when a field regeneration (started by the ECU) is in progress.
