EC25-AU "usbnet" Mode 4


We have a few EC25-AU Modems running Firmware EC25AUFAR06A10M4G.

The latest documentation for AT+QCFG Commands covers Modes 0 to 3 for “usbnet”, however, the Modem does support Mode 4 which is not currently documented.

Could someone please help with understanding what AT+QCFG=“usbnet”,4 operates as?

Thanks in advance!

Hi @AshNeilson
4 is a special MBIM interface specially developed and customized for the EM05 module. After the standard module is set to 4, if the Windows system does not support MBIM mode, the module will continuously refresh and repeatedly identify the MBIM interface.
