We are trying to see if we can use the EC25 as dialer for our monitoring systems.
Everything working as needed sofar, just stuck with playing wav files (PMC) from a directory on C:
in a voice call.
I noticed, in the Audio Player Application Note V3.1, that we can use the command
AT+QPCMD, but it looks like this is not supported on the modules we have.
What can we do ?
Firmware version is: EC25EFAR06A06M4G
P.s. Another thing I could not find is, how to have the module generate info to the serial port like:
ring ring, when module is called in ATS0=1, and phone number that is calling the module.
Thanks in advance for your info,
Hello MARcvE, thanks for your question
The AT+QPCMD command is applicable to Quectel’s GSM series products. On EC25, you can use the AT+QPCMV command to enable this function.
If you want to set the URC report of the incoming call number when ringing, you need to execute the AT+QURCCFG=“urcport”,“uart1” command to report through the serial port, and then execute AT^DSCI=1 (not save when power off) to enable the phone status report, thank you.
Hi Duncan. URC already working. Tomorrow I will see I get the audio running. Thanks a lot. Marc
Hello Quectel. I already emailed Duncan, but will place it here as well.
Since we want to use all our modems without drivers, sending the wav files over NMEA is
not a good thing, because it wont recognize the NMEA port without drivers.
I am thinking about connecting the Modem through rs232 which works. This can handle the voice call, dtmf and sms AT commands. Since it looks like I cannot send the wav files in the voice call to the modem over the same com port, I need to find another solution. Possibly straight audio out from PC to audio in on EC25 module. Any suggestions.
