The status pin cannot be used as an indication of module shutdown status when VBAT is removed.
3.13. Behaviors of the UART1_RI
AT+QCFG="risignaltype","physical"
command can be used to configure UART1_RI behaviors.
No matter on which port a URC is presented, the URC will trigger behaviors of the UART1_RI pin.
The URC can be outputted from the UART port, USB AT port and USB modem port, which can be set
by
AT+QURCCFG
. The default port is USB AT port.
In addition, the UART1_RI behavior can be configured flexibly. The default behavior of the UART1_RI is
shown below.
