4.6.4. MAIN_RI
*
AT+QCFG= “risignaltype”,“physical”
can be used to configure MAIN_RI behavior. No matter on which
port a URC is presented, the URC will trigger the behavior of MAIN_RI pin.
Table 26: Pin Definition of MAIN_RI
The default MAIN_RI behaviors can be configured flexibly by
AT+QCFG="urc/ri/ring"
*
. Refer to
document [2]
for details. The default behavior of the MAIN_RI is shown as below.
Table 27: Default Behaviors of MAIN_RI
4.7. GRFC Interfaces
*
The module provides two generic RF control interfaces for the control of external antenna tuners.

Main UART ring indication
1.8 V power domain.
If this pin is unused, keep this pin open.
State
Response
Idle
MAIN_RI keeps at high level.
URC
MAIN_RI outputs 120 ms low pulse in case of a new URC returns.
A URC can be outputted from the main UART interface (default), the CLI UART or the debug UART
through configuration via
AT+QURCCFG
.
