It depends. There are two options: 1) The device lies about its supported DMS version and it actually supports a newer DMS version, but mis-reports it. Firmware bug, but something we probably have to work around. 2) The command is actually supported in DMS 1.0 but the information we had indicated it's only supported in 1.1. libqmi bug, and we can fix this. To figure this out, let's modify an existing message that clearly isn't supported in very early DMS versions. So change the version in data/qmi-service-dms.json for the "Read User Data" and "UIM Get State" messages to "1.0" and rebuild/reinstall. Then, what is the result of: qmicli -d /dev/cdc-wdm0 --dms-read-user-data qmicli -d /dev/cdc-wdm0 --dms-uim-get-state Dan > However, ModemManager still does not work because of the other > message > (I recompiled it against the patched libqmi library): > > ModemManager[710]: couldn't load Supported Bands: 'QMI > operation failed: Cannot send message: QMI service 'dms' version > '1.3' > required, got version '1.0'' > ModemManager[710]: Modem couldn't be initialized: Couldn't > check unlock status: Couldn't get SIM lock status after 6 retries > ModemManager[710]: Modem: state changed (unknown -> failed) > > Will this allow a similar fix? > > On Wed, Sep 7, 2016 at 4:29 PM, Dan Williams wrote: > > > > On Wed, 2016-09-07 at 15:33 +0200, José wrote: > > > > > > Maybe I was wrong.

Re: QUECTEL EC20/EC21. Several drivers supported, which one is better to use?
Hi Dan, thanks for your answer. I compiled libqmi-1.12.6-r0.1.cortexa9hf_vfp_neon.rpm (notice that it is an older version, it was just simpler on my environment) with the change you proposed. After that, the command seems to work: # qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode [/dev/cdc-wdm0] Operating mode retrieved: Mode: 'online' HW restricted: 'no' So is the problem in the modem firmware reporting an older DMS that what it is really using, or is it in libqmi? However, ModemManager still does not work because of the other message (I recompiled it against the patched libqmi library): ModemManager[710]: couldn't load Supported Bands: 'QMI operation failed: Cannot send message: QMI service 'dms' version '1.3' required, got version '1.0'' ModemManager[710]: Modem couldn't be initialized: Couldn't check unlock status: Couldn't get SIM lock status after 6 retries ModemManager[710]: Modem: state changed (unknown -> failed) Will this allow a similar fix?

It may be that Get Operating Mode was present in DMS 1.0 and we simply don't have any examples of that. So you could try to modify libqmi and see if that works. Look in data/qmi-service-dms.json and look for "Get Operating Mode". Change the "1.1" there to "1.0", rebuild, and reinstall libqmi. Then see if you can run "qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode". Does that work?

The devices must be recognized by the right kernel drivers for QMI, and that means qmi_wwan. So you can look at the device list in the kernel's drivers/net/usb/qmi_wwan.c file. Anything in that list is what's currently supported for that kernel version: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/net/usb/qmi_wwan.c The 0117 device (is it a ZTE MF667?) isn't in that file, but it has a Qualcomm MDM8200A in it, so it might support QMI. The best thing to do is just add the ID and see if you can speak QMI to it.

Re: QUECTEL EC20/EC21. Several drivers supported, which one is better to use?
Hi Thomas, thanks for the advice! The EC20 is workign fine. For the EC21, I get the following error: 'QMI operation failed: Cannot send message: QMI service 'dms' version '1.1' required, got version '1.0'' I suspect that can be fixed but just upgrading ModemManager or libqmi (or maybe both). Is that correct? On Tue, Sep 6, 2016 at 9:51 PM, Thomas Schäfer wrote: > Am Dienstag, 6.
