Posted in: FAQs for MFC
Bluetooth wireless technology communication with the MFC is two way. The MFC will not do anything if it does not see (can not communicate/reach) the controller device, also the controller device will not acknowledge an action response made by the user, unless it gets a reply from the MFC (except if user is running software in simulation mode). So that way neither party (device or MFC), will not proceed with a user action request if there is a break in communication.
