USB interface is the default mode, so:
• When gateway is turned at the first time, control interface on USB is started.
• When USB cable is disconnected and USB interface is active, gateway waits for cable
connecting.
• If Set Gateway mode command (see 4.3.4.6) is sent during control interface, at the next boot
the new interface will be active.
• At boot time, if USB cable is connected, control interface will be started always on the USB.
• During functioning, if USB cable is connected, control interface on USB will be started in one
second. Old interface will be again active at the next reboot.
• To pass from control interface to transparent mode and vice versa takes at most one second.
• In order to put gateway in deep sleep, use Deep Sleep command (see 4.3.4.27). Gateway can
be woken up by user through wakeup button (controlled mode) or by RTC alarm (autonomous
mode).
• During autonomous mode, interface on GPRS is enabled: if gateway is turned on in controlled
mode and USB cable is unplugged, control interface is active on GPRS
• If reset button is pressed while gateway is going to deep sleep, system could reset two times
or go to deep sleep after a reset.
