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. ---
