File transfer on Sony Ericsson C902? #451

I'm not entirely sure whether this is really an issue with Gammu, or just my incompetence, but I couldn't get file transfer working with SE C902 on Ubuntu 18.04.

First, I tried to connect it in Mass Storage mode without Gammu, but the phone kept restarting and didn't connect properly. This has been discussed on Ubuntu Forums and they don't seem to have found an answer.

Then I tried to use USB connection with Phone Mode and set it up via Wammu UI, but both AT and OBEX options only offered me "General [AT/OBEX] over serial port or its emulation". I'm not sure I have an emulation of a serial port 🤷 and I couldn't find anything about that topic online. When I entered /dev/bus/usb/*/*, Gammu complained about not having permissions to access the device or something.

Finally I got Bluetooth connection working over AT 🎉 and I was successful to synchronize the time on my phone, but if I understand it correctly, AT can't do file tranfser, I need OBEX for that. And when I tried to set up OBEX over Bluetooth, it just restarted my phone and said that "Your phone doesn't support OBEX over Bluetooth". (Which is probably true, I think I need to do it over the cable.)

So what shall I do? Do I really need to emulate serial port somehow? And if so, could you please point me to some documentation/tutorial? I'm willing to provide more specific information if it will help.

Thank you.
