[sceddd]

Have you got any idea yet?

[pswiatki]

Use iosm with the startup scripts here - it will be easier. Or check out Modem Manager patch which can now connect and disconnect nicely. That will make things even easier.

[malemuk]

Could you explain how to use iosm or how I install the Modem Manager patch?

[impactevent]

@pswiatki Are you able to write something more? How to do it?

[pswiatki]

Yes. I will post a link to the appropriate MM branch.

[pswiatki]

Here is the link to MM branch and also Thomas Vogt's request for help testing it: #225
So: I wish you good luck, guys!

[malemuk]

Thanks!

[impactevent]

Not Working :(
Point 4
Last step ninja -C build install

[pswiatki]

Use the second description further down. Thank you for your understanding.

[impactevent]

@pswiatki thank you, but what second description ? ;)

[pswiatki]

Didn't I put a link directly to it? If you can't reach it - read the thread carefully and you will know all you need to know. Good luck!

[impactevent]

@pswiatki you do, and it looks like this branch is not working, can't build on it, still have the same error ..

../src/plugins/quectel/mm-port-mbim-quectel.c: In function ‘iface_port_at_check_support’:

On branch ModemManager-port-xmm7360

Maybe I have some mistake in this step sudo apt build-dep modemmanager libmbim originally I didn't have the source list loaded at /etc/apt/sources.list.d/ubuntu.sources so i add manually:

Types: deb-src
URIs: http://in.archive.ubuntu.com/ubuntu
Suites: noble noble-updates noble-backports
Components:  main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Ubuntu 24.04

[pswiatki]

I did it on ARCH Linux and was lucky (?) enough to manage everything nicely. Just followed the instructions and explanations given by Thomas (The Author). I never used Ubuntu with xmm7360 device. I am sure you will be able to succeed - just follow everything precisely and understand what is needed to make it work. Good luck!

Changing line 1281 of xmm7360.c from:

static int xmm7360_tty_write(struct tty_struct *tty, 
                             const unsigned char *buffer, int count)

to:

static ssize_t xmm7360_tty_write(struct tty_struct *tty,
                            const u8 *buffer, size_t count) 

and then:

make CFLAGS="-Wno-error"

allowed make on Ubuntu 24.04 6.8.0-45.
