Freematics OBD-II Emulator

Postby User » Wed Jun 12, 2019 6:47 pm


I'm using your OBD-II Emulator (MK2),
it seems the Emulator is not conform with the OBDII standard protocol well, my device work great on cars, but with Emulator its not recognize Engine on or off. im using ulbotech T381 Device.

i search in your site and don't find any updates for the GUI or the Emulator, are you still support and maintenance this product ?

Best Regards

As a suggestion, most devices expect a certain level of voltage to detect ignition on. This is because vehicles are typically around 11v on the OBD port when the vehicle is off, and around 14v when the vehicle is ignition on.

Try using a variable power supply providing power to the Freematics device. Otherwise you're probably not going to have much luck.
