Should connect and show data.

Did you try to pair device in Bluetooth Settings first? We would need to have logs to see what's going on (Help -> Logs), you can attach here as zip file

Yes, and it doesn't, but I think the problem is that BLE devices generally don't pair like normal Bluetooth devices do..

The issue is likely that the scanner is specifically designed to work only with the Carly app. We are aware of a similar issue with OBDeleven.

Here's the log file, I can't find anything related to the plugin:
logcat(2).log

I also noticed that I can't see the other buttons (settings, rename, forget) when trying to connect to the device

Expensive devices usually have own protocol or custom way to communicate. So far we support simple Bluetooth devices, these devices usually needs to be paired first as Bluetooth device.

We will add more logs to understand what went wrong and how it could be implemented. Unfortunately CarScanner is not opensource to understand what's specific Carly has.

Thanks, let me know if I can provide more logs.

Yes looks like we need to get BLE-device for testing purposes and implement it cause Bluetooth differs from BLE.

That's what I suspected, maybe the implementation of BLE in KartaView helps:
