EM7565 QMI mode?

[swwifty]

I tried to put my EM7565 in QMI mode for some testing (it was in MBIM) now GoldenOrb can't talk to the modem. I see it pop up and is detected by the kernel, but I can't talk to it.

I ran the following command to put it in QMI mode:

at!usbcomp=1,1,10d

Any ideas how to rescue my modem? I'm thinking slap it into my Linux laptop and send some at commands to change it back, but not sure what tools I can use to do that.

well I got it out of QMI mode via my Linux laptop, but its still not working.....

That is the wrong command for QMI on the EM7565. It takes:

Code: Select all

at!usbcomp=1,3,10d

What are its symptoms?

GoldenOrb just doesn't see the modem, even though it shows up in the kernel logs.

Maybe I issued the wrong command for MBIM mode as well? Although the kernel sees it come up in MBIM currently.

That is most likely the issue. MBIM is:

Code: Select all

AT!USBCOMP=1,3,1009

AT!USBCOMP=1,3,1009

OK, trying that now.

That fixed it, apparently at!usbcomp=1,1,10d or at!usbcomp=1,1,1009 only works on MC7455 modems.

Strange thing is, it said in the kernel output it was in MBIM and QMI mode the whole time.

It is, only it removes the modem WAN port.

Thanks for the help Jim.
