To those who still have a problem with connecting OBD devicenamed differently than "OBD".
I have a Vgate OBD2 interface which is additionally secured by PIN 1234 that is needed to connect. Unfortunately, it is shown as mobile while searching for the BT devices. Here is what I did to get this working (using ES File explorer Pro):
1. Be sure that you have Xposed framework and MTC-Manager module installed. (You can find it
HERE)
2. Create "mtc-manager" folder on external sd card.
3. Create a file settings.ini withing that folder.
4. Open the file and type there: obd_device=Vgate (where 'Vgate' is your BT device name of OBD interface)
5. Restart the unit.
6. If your BT device is connected - disconnect it!
7. Go to BT settings and hit 'find devices' button (be sure that your OBD device is now disconnected and it is not listed)
8. When the searching is finished - connect your OBD device, turn the ignition ON and then hit 'find devices' once again.
9. This time your OBD device should be found and listed with OBD icon instead of mobile icon - if you managed to achieve this, we are at home

10. Simply pair your OBD device.
11. Be sure that appropriate device is chosen in Torque.
@Malaysk I think that this guide could be added to the first post somewhere
