uqmi and Raspberry

[lotte67890]

I wonder if anybody ever had or has succesfully communicated with uqmi to a modem on /dev/cdc-wdmX... All I can find on the Internet is that some people struggled and all which had success use the X86 platform...

I want to use the uqmi application on my Raspberry2, but I´m unable to communicate with my Huawei e3372h (patched to work as modem notg as route, so it´s a non Hilink Version).

What I know:

The Modem works under Ubuntu using networkmanager with settings APN, User, password and number.
Since there is no ARM package for Picore 9.03 I compiled uqmi myself which worked without any errors. I installed all the files to the appropriate dests and added them to /opt/.filetool.lst
The modem is detected by the system, creating /dev/cdc-wdm0 and after modeswitch from 14fe to 1506 /dev/ttyUSB0 and /dev/ttyUSB1 devices

But whatever I try, no communication with the modem...

Anybody any hint or knows another application than uqmi to initiate a connection? In the end a ppp connection should work as well, but since I can´t get compiled wvdial, I struggle of how to should initiate the connection and which AT Parameters to use...

Thx a lot in advance

Also check the device rights.

With ls -l  /dev/ttyUSB0 so the user can access the device.

Many tty uses the uucp as group, or even the group ppp.

So you want to add the user or program that have access to the device.

You should also try to use some small program to access the serial device, like screen, cu and minicom.

Code: (bash) [Select]

sudo screen /dev/ttySUSB0 115200
sudo screen /dev/ttySUSB1 115200

[lotte67890]

Thanks patrikg! Sounds like a very good idea, but obviously, that didn´t help either... What I achieved today is that with mincom I can communicate with the modem and send commands... But now I need something to "dial/initiate connection" with. As said, wvdial would be my choice, but I struggle with a compile error...

[patrikg]

Yeah
have you seen this page...can't read german.
But i think you can use google translate.

[lotte67890]

Thanks again, that´s the site where I got the firmware from, and as said, it´s working under ubuntu. I tried to be so smart and find a compiled version of wvdial in an raspian package, unfortunately it´s linked against other libs, so no luck again...
Next try will be to dial with minicom but I´m unsure if that can be automated...


Peace

Hi lotte67890

... As said, wvdial would be my choice, but I struggle with a compile error...

If you post the error, someone might be able to help you.

[Juanito]

a bunch of patches are needed, see:

http://tinycorelinux.net/9.x/x86_64/tcz/src/wvdial
http://tinycorelinux.net/9.x/x86_64/tcz/src/wvstreams

[Juanito]

..or you could try using mmcli/nmcli from modemmanager/networkmanager

[lotte67890]

Juanito, thank you very very much! I first tried with wvdial and noticed that now I can succesfully compile wvstreams, but wvdial still gives me an error:

Code: [Select]

* Generating CC
* Generating CXX
linking wvdial...
wvdial.o:(.data.rel.ro+0x100): undefined reference to `typeinfo for WvLogConsole'
wvdial.a(wvdialer.o):(.data.rel.ro+0xd8): undefined reference to `typeinfo for WvStreamClone'
collect2: error: ld returned 1 exit status
make: *** [wvrules.mk:155: wvdial] Error 1
It doesn´t matter if i run make as user tc or with sudo.

I then saw your note about using NetworkManager, so I started connecting wlan first using NM. I created /usr/local/etc/NetworkManager/system-connections/MyWlanNetwork
Struggled a bit till I found out that I need to have wpa_supplicant to feed NM needs, and now have in /opt/bootlocal.sh:

...

Code: [Select]

# ------ Put other system startup commands below this line
/usr/sbin/usb_modeswitch -s 15 -J -c /etc/usb_modeswitch.conf
/usr/local/etc/init.d/dbus start
/usr/local/etc/init.d/networkmanager start
/usr/local/sbin/wpa_supplicant -u -B -i wlan0 -D wext
sleep 3
/usr/local/etc/init.d/dbus reload
sleep 3
/usr/local/bin/nmcli c up MyWlanNetwork
Before not having the sleep commands The system failed to initiate the wlan connection on boot. But now it works, I get an IP address and a route, although I wonder why having Destination 10.143.31.0 twice, shouldn´t one be enough?:

Code: [Select]

tc@DRM0:~$ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         10.143.31.1     0.0.0.0         UG    600    0        0 wlan0
10.143.31.0     *               255.255.255.0   U     203    0        0 wlan0
10.143.31.0     *               255.255.255.0   U     600    0        0 wlan0
127.0.0.1       *               255.255.255.255 UH    0      0        0 lo
Anyway, next is the modem. If I run:

Code: [Select]

tc@DRM0:~$ nmcli d
DEVICE  TYPE      STATE        CONNECTION
[color=green]wlan0   wifi      connected    MyWlanNetwork  [/color]
eth0    ethernet  unavailable  --         
lo      loopback  unmanaged    --     

So no modem here, and I have no clue how to create it. How does NM find the device? There is no /etc/network/interface which could interfere and /usr/local/etc/NetworkManager/nm-system-settings.conf is a symbolic link to /tmp/tcloop/networkmanager/usr/local/etc/NetworkManager/nm-system-settings.conf which is on a ro mounted filesystem (as you certainly know...). I was hoping that with the option managed=true in the NM.conf file the system will detect the modem. Does it conflict with the wpa_supplicant options I passed in /opt/bootlocal.sh? Are any extra options required? Or do I miss something in general? Modem is present in dmesg same as in Ubuntu and devices are /dev/cdc-wdm0 as long as /dev/ttyUSB0 and /dev/USB1.

Thanks a lot

Lothar

    [EDIT]: Added code tags.  Rich

[Juanito]

Loading networkmanager will load the wpa_supplicant-dbus extension anyway.

In the past I'm pretty sure I used nmcli commands to create a wifi connection without using wpa_supplicant directly and, once done and the connection config added to a backup, networkmanager connected automatically on reboot.

For the modem, perhaps you need modemmanager mmcli commands to bring it to life?

For the wvdial error, are you missing glib2-python perhaps?

[lotte67890]

Well, I couldn´t find wpa_supplicant in the processlist and when starting it without any options I couldn´t activate my Wlan USB dongle cause of the wrong module, I needed to pass wext.

For the wvdial, yes glib2-python is installed including dev.

Your hint with ModemManager was absolutely correct! The modem now dials and connects although it disconnects immediately after the connection is established...:

I checked against the log from the Ubuntu installation and all the other parts of the log seem more or less identical, at least I couldn´t find anything... What´s different is the version, Ubuntu uses 1.4.12, Picore ModemManager is 1.6.12.

If I create a new connection in Ubuntu exactly the same as I did under PiCore (copy/paste) the modem connects at once and is quite fast, 120Mbit down and 42 Mbit upload...

I googled around but can not find a specific cause for this behavior...
Maybe I need a little sleep and start to have a look over afterwards...

I don't have the hardware to test, but I'd guess you could do something similar for your modem

[lotte67890]

Good morning Juanito, well that´s exactly what I´m doing, I started ModemManager, it finds the device, which I then can see in NetworkManager, then created a profile and connect as you did. And as written in the logs I see the connect but directly afterwards...

Code: [Select]

<info>  [000094.685391] Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected)
<info>  [000094.686746] Simple connect state (8/8): All done

<debug> [000094.881168] Sending PDP context deactivation in primary port...

I have no clue why the bearer is disconnecting.

I will try with wrong credentials and see what´s happening then, and I´m thinking of Pap/Chap/Authorisation... But when using under Ubuntu it works with the same profile creation...

Merci

I originally thought mmcli was the way to go, but perhaps it can be done from nmcli directly (or after "mmcli -m 0 -e")?

What does "nmcli r" show for you?

For me, the wifi hardware was not listed with "nmcli c show" until after I connected.

Perhaps "nmcli d wwan connect ..." or similar (replace wwan with gsm) is the way to go?

Maybe this would help:
