Galaxy S9+ connection issues

Unable to connect to the ECM using the Galaxy S9+ and an OBDLink SX serial cable. I set the S9 USB to be controlled by the connected device and to allow transferring of files. I am able to connect to other apps using the cable. I also logged the process in the app and submitted it to the developers.

Any help would be greatly appreciated.

Thanks

OBDLink SX is in our test set so it ‘should’ work. I will take a look at your log.

You are using wrong baud rate setting of 4800 baud.

I think the baud rate of OBDLink SX is configurable, but should be 115200 by default.

That worked - Thanks for the help
