URC +QTONEDET and CMUX

IoT Modules LTE Standard Module
1

Hi, I’ve activated the cmux in default mode and the URCs are forced to cmux/port 2: AT+QCFG=“cmux/urcport”,2
I’ve started 4 cmux port.
On the cmux/port2 I’ve activated the DTMF detection: AT+QTONEDET=1.
I expected the URC +QTONEDET in the cmux/port2 only, unfortunately the URC is repeeted to all cmux port (like a RING). This is a problem for me. Do you have any idea why? Can you help me solve the problem?

My module is:
EC25 EUX
Revision: EC25EUXGAR08A08M1G

Hi Tommy
You can configure the URC reporting port through AT commands. The specific AT commands are as follows: AT+QURCCFG=“urcport”[,<urc_port_
value>]

Hi FelixCheng
I know the AT+QURCCFG command but I think is not good for configuring URC on cmux ports.

AT+QURCCFG=?
+QURCCFG: “urcport”,(“usbat”,“usbmodem”,“uart1”,“uart2”,“all”)
OK
As you see I dont know how I can solve the problem.
Let me know if I’m wrong
