I am a new owner of the software, purchased through the apple App Store. I have a iPad pro that is new as well and the OBDII wi if interface scanner that is iOS ready. So I plug in the interface and it shows a red light and started the car, launched the app and no interface - no information. I verified that the wi-fi was being detected by the iPad as well.
I'm not sure where the fault is. Do I need other software for the OBDII to function?
