NOTE:
When the UART signals are used as the communication port between the
host and the modem:
•
The DTR pin must be connected to enter LE940B6 power saving
mode.
•
The RI pin must be connected to wake up the host when a call is
coming while the host is in Sleep mode.
•
The RTS must be connected to GND (on the module side) if flow
control is not used.
If the UART port is not used, all UART signals can be left disconnected.
