It is only when connected to an OBD diagnostic scanner that is actively scanning, and not when connected to an OBD monitoring device that the Freematics Emulator generates a CAN signal. This is not realistic for most cars, where we should expect to see signal activity on CAN when passively listening...

My Freematics Emulator doesn't generate any signal when any of several off-the-shelf OBD dongles are connected. I found one OBD dongle for which it does generate signal, which is the OBDLink EX (when in the connected mode, per its OBDWiz GUI) . Can you clarify what electrical characteristic or behav...

Hi Freematics, I've found that my Freematics Emulator has no detectable signal on CAN, unless it is connected to an OBDLink EX, and then only when the OBDLink EX is in 'connected' mode with its OBDWiz GUI application. When this is the case, I measure 20mV between CAN_H and CAN_L, and can read CAN tr...
