4.9. Behaviors of the MAIN_RI
AT+QCFG="risignaltype","physical"
can be used to configure MAIN_RI behaviors. No matter on which
port a URC is presented, the URC will trigger the behaviors of MAIN_RI pin.
The URC can be outputted via 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, MAIN_RI behavior can be configured flexibly. The MAIN_RI behavior can be changed via
AT+QCFG
. See
for details. The default behavior of the MAIN_RI is shown as below.
Table 24: Behaviors of the MAIN_RI
The status pin cannot be used as indication of module shutdown status when VBAT is removed.
