Before connecting the app, you have to pair the smartphone/device to the OBD adapter using the standard Android bluetooth connection menu.
To be paired, the adapter must be powered on (connected to the car or to a 12V supplier).
When your adapter is paired, you have to setup the connection in the VAG DPF options menu:
- open the app
- click the Settings icon (gear icon at the top-right of the screen)
- scroll down to Adapter options section
- select Bluetooth in Connection type (grant the permissions if requested)
- select the adapter name in Select Bluetooth ELM327 (the list contains all paired adapters, if you can't find the adapter name, check again the pairing or pair it again)
- exit Settings menu
- press CONNECT button if you want to connect or quit the app
Connecting with WIFI ELM327 adapter
Before connecting the app, you have to connect the smartphone/device to the adapter WIFI network using the standard Android WIFI connection menu; usually, if the adapter network was already saved, enabling the WIFI on your device should establish the connection.
To be visible, the adapter must be powered on (connected to the car or to a 12V supplier).
When your adapter network is connected, you have to setup the connection in the VAG DPF options menu:
- open the app
- click the Settings icon (gear icon at the top-right of the screen)
- scroll down to Adapter options section
- select WIFI in Connection type
- you don't have to select any adapter in the list because the app uses the WIFI network connected in that time
- exit Settings menu
- press CONNECT button if you want to connect or quit the app
Please note that some smartphone/device can disconnect the adapter if a valid internet connection ins't available; in this case you should find in the smartphone/device an option to keep the Wifi connection open even if an internet connection isn't available.
