I want to listen to RI pin to know when an SMS is coming. From the manual it says I can set pulses of RI with the AT command:
‘AT+QCFG=“urc/ri/smsincoming”,“pulse”,2000,3’
I send the command and I have OK as a reply. The problem is that when I send an SMS to the SIM that is being used, I don’t measure any status change of the RI pin. Also, the STAT LED signals the SMS incoming. What am I doing wrong?
I don’t know how to edit and so I’m going to explain in more detail the problem.
The Quectel EC25 Manual, under the Status Control Commands, says that we can configure RI pin status with the AT command:
‘AT+QCFG=“urc/ri/smsincoming”,“pulse”,2000,3’
With this example, it configures the RI pint status to send 3 low pulses of 2000ms, every time it receives an SMS.
The problem is that when I send an SMS, I don’t measure any 2000ms pulse. Not event one. The RI pin continues fixed that the same level.
Hi @miguel.won,
Configure RI signal for ring/SMS interrupt using the command below.
'AT+QCFG="risignaltype","physical"'
