Figure 31: Reference Circuit of the STATUS
1. In sleep state, STATUS will still output a low voltage to drive the LED, causing an extra current
consumption on VBAT. So it is recommended to replace VBAT with an external controllable power
supply, and use it to switch off the power source during sleep state so as to reduce power
consumption.
2. It is not recommended to use level translator circuit for STATUS.
3.20. Behaviors of RI
AT+QCFG=“risignaltype”,“physical” command can be used to configure RI behavior.
No matter on which port URC is presented, URC will trigger the behavior of RI pin.
URC can be outputted from UART port, USB AT port and USB modem port by AT+QURCCFG command.
The default port is USB AT port.
The default behaviors of RI are shown as below.
