Behaviors Of The Uart1_Ri - Quectel UG89 Hardware Design

Pin Name Pin No.
STATUS 53
The following figure shows different circuit designs of STATUS, and customers can choose either one
according to the application demands.
NOTE
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.
NOTE
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.
