Questions[huawei](ubuntu)

I am running Ubuntu 18.04 and I am trying to use Huawei Freebuds 3 over Bluetooth.

I have no problem during pairing and with the output sound, but I cannot make the microphone works.

I have checked the pactl list and this is the output:

        Driver: module-bluez5-device.c

        Properties:
                device.description = "FreeBuds 3"
                device.string = "FC:94:35:BA:C6:A4"
                device.api = "bluez"
                device.class = "sound"
                device.bus = "bluetooth"
                device.form_factor = "headphone"
                bluez.path = "/org/bluez/hci0/dev_FC_94_35_BA_C6_A4"
                bluez.class = "0x240418"
                bluez.alias = "FreeBuds 3"
                device.icon_name = "audio-headphones-bluetooth"
        Profiles:

                headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 30, available: no)
                off: Off (sinks: 0, sources: 0, priority: 0, available: yes)
        Active Profile: a2dp_sink
        Ports:
                headphone-output: Headphone (priority: 0, latency offset: 0 usec)
                        Part of profile(s): a2dp_sink, headset_head_unit
                headphone-input: Bluetooth Input (priority: 0, latency offset: 0 usec, not available)
                        Part of profile(s): headset_head_unit

I have tried to change the profile of the Freebuds (e.g. from Blueman GUI) to headset_head_unit but I was unable to do so and from /var/log/syslog the only related error that I can see is pulseaudio[3175]: [pulseaudio] module-bluez5-device.c: Refused to switch profile to headset_head_unit: Not connected even if the device is connected.

Anyone can help me?

I have a problem with pairing Huawei's Freebuds 3 via bluetooth on Ubuntu 18.04. I have already updated bluez til 5.50. All I got when pairing is a loading circle and then message Not set up. Does anyone got a clue?

Part of syslog looks like that during pairing:

I'm working on an HP machine with Ubuntu 16.04 installed and kernel 4.10.0-42-generic #46~16.04.1-Ubuntu. I want to use a Huawei ME906s-158 to connect to a mobile network, which is unfortunately mostly not working.

If I plug in the device, I can sometimes use it as expected with the graphical network manager tool. But after a few minutes (mostly after only a few seconds) the connection suddenly disappears without any error message. The network manager shows the device under wired connections as Ethernet Network and disconnected, and it is grayed-out. Often it is not detected as mobile broadband device at all and is shown as wired connection as described before.

I googled a lot but found no solution, which is why I try to get your help here. Please tell me which information you need to help me, these are things I tried:

i) This is the output of "dmesg" when no connection is established

v) The behavior seemed to occur suddenly. I bought these modules about a month ago and tried them to check whether they are defective or OK, and I can't remember that I experienced similar behavior. It then occured yesterday after the cards where stored in my cupboard.

vi) I tried to setup udev rules, as it is recommended in several forums. I installed usb_modeswitch in version

usb_modeswitch: handle USB devices with multiple modes
 * Version 2.5.0 (C) Josua Dietze 2017
 * Based on libusb1/libusbx

and added

ATTR{idVendor}=="12d1", ATTR{idProduct}=="15c1", RUN+="usb_modeswitch -v 0x12d1 -p 0x15c1 -u 3"

to the "40-usb_modeswitch.rules" file in the beginning, but it did not help.

vii) If I try "usb_modeswitch -v 0x12d1 -p 0x15c1 -u 3" in the console it shows:

Look for default devices ...
   product ID matched

viii) I'm not bound to the network-manager, and tried to setup the connections in its files directly, but the same behavior occured. Until now I did not install other software to setup the my connection. Should I give it a try? Can't I do it without installing another tons of libaries?

ix) This strange behavior occurs with three devices of the same type and three SIM-cards, also of the same type and provider. I also tried to get the modem working on two more computers, one (near) fresh Ubuntu 16.04 installation and one Ubuntu 17 installation. The behavior is the same on both. Until now I did not test with SIM cards of other providers, I will try to do so as soon as possible.

Is there anybody who can help or knows the problem? Thank you very much for your help. Martin

I got a Huawei ME906s data card which also has a GPS function. I wonder how to get the GPS working on Ubuntu 16.04.

I'm using USB 3G Dongle for Internet. Previously I was using Tata Docomo (India) as provider, and the Internet was working fine. Now I've changed to BSNL, but I'm unable to connect to the Internet on Ubuntu. However, I've checked access point settings and other configuration which are required for BSNL, and it is working fine with same Dongle on Windows 7. Also, I'm able to connect Internet with other providers on Ubuntu, but problem persists only with Ubuntu. The access point for BSNL in my region is bsnlnet. In fact I configure the Dongle with BSNL using default Network Configuration wizard that pops up when USB Dongle is attached.

When Dongle is attached and configured with BSNL, I can see network strength in Messaging menu, in Mobile Broadband category, of Ubuntu (note: my network icon still shows "not connected" status). And when I try to use the connection that I've created, it fails to connect. So far, I tried using Sakis3g script that I came up with while wandering over this issue on other forums, it didn't worked either. I also made sure that there are no special configuration made for BSNL on my Windows 7 installation, and still it is working fine there, the problem is only with Ubuntu.

How can I fix it?

Update:

While I was unable to fix the issue in Ubuntu 11.10, it still exists in 12.04 too. I hope someone finds a solution and posts it, as I want to become full time Ubuntu user but only way to connect internet in Ubuntu for now is to use other provider.

And I bet the problem has something to do with providers network band-type. Since both Tata Docomo and BSNL operate on different GSM band, while in Windows, Huawei Mobile partner manages this and I can use any GSM provider to connect with Internet, I guess this is not happening with Ubuntu, and I can only use Tata Docomo and other providers which operate on same band.
