Hi, I’m running Quectel EG25-G with firmware EG25GGBR07A07M2G_01.001.01.001. I need USB Audio Class (UAC) support so the modem exposes a /dev/snd sound card for VoIP voice. Per this forum thread, a firmware variant with the last two AT+QCFG=“usbcfg” bits enabled exists. Could you please share the latest UAC-capable firmware (and flashing instructions) for EG25-G? Current usbcfg is 0x2C7C, 0x125, 1, 1, 1, 1, 1, 0, 0.
Possible to get new firmware?
