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]: <warn> couldn't load Supported Bands: 'QMI > operation failed: Cannot send message: QMI service 'dms' version > '1.3' > required, got version '1.0'' > ModemManager[710]: <warn> Modem couldn't be initialized: Couldn't > check unlock status: Couldn't get SIM lock status after 6 retries > ModemManager[710]: <info> Modem: state changed (unknown -> failed) > > Will this allow a similar fix? > > On Wed, Sep 7, 2016 at 4:29 PM, Dan Williams <d...@redhat.com> wrote: > > > > On Wed, 2016-09-07 at 15:33 +0200, José wrote: > > > > > > Maybe I was wrong.
