4.4 LTE Low Power Mode
4.4.1 General Information
Important: The GM01Q module is provided with an internal RTC whose
supply is VBAT1. As a consequence, VBAT1 should not be
removed, in order to keep RTC active.
The GM01Q will automatically enter in low-power mode. GM01Q can be
woken from low power mode by external sources through:
SIM_DETECT input signal to cope with SIM card insertion or removal into
a SIM card connector with built-in hardware detection.
The RTS0 input signal whenever data traffic is initiated by the host
connected to the module UART0 with hardware flow control; The default
configuration to wake-up the module is low level.
Two dedicated input signal WAKE0 and WAKE1. They are not configured
by default as wake-up source but a persistent AT command can enable
them. For instance, WAKE0 or WAKE1 can be used to detect an alarm from
an external IC such as a sensor.
