Hello,
I am using a Quectel EC25-EU and would like to request the latest firmware and the appropriate firmware upgrade tool for my exact module.
Module: EC25-EU
Current firmware: EC25EUGAR06A05M4G
USB VID/PID: 2C7C:0125
Current USB configuration:
+QCFG: "usbcfg",0x2C7C,0x0125,1,1,1,1,1,0,1
I have enabled USB Audio Class with:
AT+QPCMV=1,2
and the modem reports:
+QPCMV: 1,2
Voice calls themselves work correctly, but USB UAC call audio does not work in either direction: I cannot hear the remote party through the UAC capture device, and audio played through the UAC playback device does not reach the remote party.
Could someone please provide the latest firmware applicable to this exact EC25-EU variant, preferably with the appropriate QFlash/QFirehose upgrade tool and any relevant release notes?
Thank you.
