[aha999]

Describe the bug andrOBD doean't connect to a Car with Vlink iCar Pro. It connects to the adapter, but it dosconnects.

To Reproduce Steps to reproduce the behavior:

1. Adapter inserted, car contact on
2. try to connect with androbd
3. It says ECU Detect..., then "Disconnected... Connecting... Disconnected...", and it repeats.

Expected behavior Program should connect to the adapter and car and show data.

AndrOBD Debug log files AndrOBD.log.0.txt

Important details on your environment:

• Android OS version 11
• AndrOBD version 2.5.2
• OBD adapter type Vgate iCar Pro, Bluetooth 4.0 BLE
• Adapter product website: link
• Connected vehicle Citroen, Berlingo, 2005, 2.0 Diesel

Additional context I assume it's the car's fault, because it also doesn't connect with both proprietary OBDLink MX and ObdLink app. If you need more data, i can select the diagnostic output to more fine.

Adapter test with proprietary ELM Identifier app on this car where the error occured:

It really looks like your car doesn't talk OBD protocol.

Within the log file, on the OBD connection attempt to your vehicle the adapter reponds UNABLETOCONNECT. This means it tried to contact the ECU using all known OBD transport protocols (CAN, ISO141 ...), but didnt't get any valid response from the vehicle.

ok, maybe i will figure out why.

EDIT: i checked the OBD fuse, and it is in normal condition... so what else could be wrong is beyond me.
