Power Off
Turning off of the device can be done in two ways:
• via AT command (see ME910C1 Software User Guide, AT#SHDN)
• by tying low pin ON_OFF*
Either ways, the device issues a detach request to network informing that the device will
not be reachable any more.
To turn OFF the ME910C1 the pad ON_OFF* must be tied low for at least 3 seconds and
then released.
NOTE:
To check if the device has been powered off, the hardware
line PWRMON must be monitored. The device is powered
off when PWRMON goes low.
In order to avoid a back powering effect it is recommended
to avoid having any HIGH logic level signal applied to the
digital pins of the ME910C1 when the module is powered
off or during an ON/OFF transition.
