Turning off the LE910Cx Module
Turning off the device can be done in the following different ways:
• Shutdown by software using AT#SHDN software command
• Hardware shutdown using ON_OFF_N pad
• Hardware Unconditional Shutdown using the SHDN_N pad
When the device is shut down by a software command or a hardware shutdown, it issues
a detach request to the network, informing the network that the device will not be
reachable any more.
NOTE:
To check if the device has powered off, monitor the PWRMON hardware
line. When PWRMON goes low, this indicates that the device has powered
off.
NOTE:
To avoid a back-powering effect, it is recommended to avoid having any
HIGH logic level signal applied to the digital pins of the module when it is
powered OFF or during an ON/OFF transition.
