Not sure you noticed but the OBDView only works for 15 minutes per session without the plugin purchase.
A) Are you sure there is no other app taking control of the OBD connection
B) Have you tried changing all sensors to see if there is a particular sensor crashing the connection? For example make all sensors show coolant temperature. To change a sensor press and hold on top of it until a dialog pops-up.
I bought the plugin yesterday and it does not display the message about that (as it does for the maps view which I did not buy yet)
A – I am sure. On one phone and the head unit there are no OBD apps installed. It is the same setup that used to work on the non-beta, stable version.
B. Will try today and let you know. I have also attempted to delete everything from the Reader configs commands, but again apparently it did not make any change.
