5.3 Power off
Turning off of the device can be done in two ways:
• via AT command (see LE910 V2 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 LE910 V2 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 LE910 V2 when the module is powered
off or during an ON/OFF transition.
