Hey, I am running into a problem when using spacebar: the program does not display any text messages that are coming to the sim card.
I admit, my setup is a bit unique, ut I see no reason why it should not work. I am using plasma mobile on my PC (alongside with plasma wayland). My usb gsm modem interfaces on ttyUSB0, and I can get sms messages using wvdialconf and gammu (after using gammu-config).
In contrast spacebar does not display any sms messages, and I can’t figure out a way if spacebar is even detecting the serial device of the modem. It would be nice to have some feedback in the settings page about being connected to the cellular network or something like that. I guess the spacebar backend does not try to configure serial modem devices maybe?
No, in fact mmcli reports: “No modems were found”
I can still use the modem fine with the method mentioned earlier… I guess it is a problem with mmcli rather than spacebar - although spcebar could still add more backends?
I imagine the new plasma 6 modems tab in system settings also uses the same backend. That does not work either.
I don’t think that is the case - I have to manually run wvdialconf and gammu every time, it does not start automatically. Before running these the device should not be locked.
When I run fuser /dev/ttyUSB0
the result is empty, the return value is 1. lsof gives a warning:
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc
Output information may be incomplete.
If I run wvdialconf nothing changes in the fuser and lsof output. If I run mmcli now it still cannot detect the modem. If I run gammu getallsms it can download all text messages. Afterwards running fuser and lsof again, result are the same.
At this point I’d say mmcli simply does not support my modem for some reason. I think the modem is simply a serial device and uses some ancient AT protocol to communicate, so mmcli not supporting everything is a bit strange, who knows?
When wvdialconf initiates the modem (has to be run after every usb plug-in) the following is displayed:

While it would be nice to use spacebar to send and receive text messages, I think this is an mmcli problem, so maybe we should not spend any more time on this. But thanks for all the help!
