Turning off the LE910Cx Module
Turning off the device can be done in the following different ways:
Shutdown by software using the 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 hardware shutdown, it issues
a detach request to the network, informing the network that the device will no longer be
reachable.
Note:
Waiting time for the AT commands answer can vary between
different LE910Cx variants, between 2-6 sec.
Note:
To check if the device has powered off, monitor the
PWRMON/SW_RDY hardware line. When PWRMON/SW_RDY goes
low, it means the device has powered off.
