I'm newbye in this area, so I apologize in advance if I will ask something stupid. Shortly, I'm writing a software on top of connected cars that means that we are going to decorate and package data coming from an OBD_2 dongle.
Now, we are testing our product on a new Mercedes with connect.me service already installed. This service gets data throw another dongle plugged to the obd port (in the dashboard).
So in our case, the car has 2 dongles reading data from obd port.
The problem is that when we plug our device in,the dashboard shows an error message saying something like "limited me.connect service"
What are the reasons of this conflict? How can a read only device cause problem to another?
I'm sure I didn't use the right words but the point is how ro devices can cause problems each other.
