How to connect (Generic Bluetooth scanner on Android)

In most cases, you don’t need to do anything special in order to connect to your ELM327 Bluetooth device with Carista: the app automatically detects your device and connects to it. If this is the first time you are connecting to the ELM327 device, Carista might take some extra time to find it and connect to it (up to a minute) and you may be prompted to enter a PIN code (try 1234 or 0000 or consult your device’s manual). If Carista doesn’t automatically find your device, you can pair with it from your Android Bluetooth settings like you pair with any other Bluetooth device.
