Support
If the connection fails
Check adapter power, the selected device or network and the required Android permissions, in that order. If another app is using the same adapter, end that connection before retrying. If the adapter responds but the vehicle does not, check the conditions specified by the manufacturer.
For support, note the message, when it appears, your app and Android versions and the adapter model. Do not send passwords or personal vehicle identifiers. Do not erase your data and profiles just to retry a connection.
When a reading is unavailable
First check the connection status and whether other readings are present. Different vehicles expose different parameters. A reading may require particular conditions or may be a calculation whose inputs are missing.
An empty field is not automatically a measured zero. A Full licence removes relevant software restrictions, not limitations of the vehicle electronics. When asking for support, give the exact parameter name, unit and what the screen shows.
Choose the correct profile
If a feature asks for a profile, open the vehicle list and select the correct one or complete the required information. Do not assign one car’s data to another simply to dismiss a message.
Follow the app’s instructions and use reliable information. Reading a value and saving it in history are separate matters: check what has actually been saved for the selected vehicle.
