HOWTO - Mobile Broadband - Fibocom L860-GL - xmm 7560

Let's collect findings to get the Modem running, then write an article on the wiki.

I will update with my state of progress, so far:

  • FCC unlock - seems to work

  • nmcli radios - without FCC unlock - gives me this response

    WIFI-HW  WIFI      WWAN-HW  WWAN
    enabled  disabled  missing  enabled
  • mmcli -L

    No modems were found
  • lspci -nn

    08:00.0 Wireless controller [0d40]: Intel Corporation XMM7560 LTE Advanced Pro Modem [8086:7560] (rev 01)
  • rfkill

    ID TYPE      DEVICE                   SOFT      HARD
    1 wwan      tpacpi_wwan_sw      unblocked unblocked
  • FCC unlock - needs to be done after every boot

    sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
  • enabling the modem

    mmcli --modem=0 --enable

    or if pin isn't disabled

    mmcli --modem=0 --sim=0 --pin=****

    checking the state again

    mmcli --modem=0 --sim=0

    results in something like this

    -------------------------------
      General    |              path: /org/freedesktop/ModemManager1/SIM/0

  • trying to enable the modem

    sudo mmcli --modem=0 --enable

    still gives an Error - any info what "Invalid transition" means welcome

    error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Retry: Invalid transition'
  • using simple-connect to connect to APN

    mmcli -m 0 --simple-connect='apn=YOUR.4G.PROVIDER,ip-type=ipv4v6'
  • getting the bearer ?? not shure about the process here

    sudo mmcli --modem=0 --bearer=0

    results in this Error - probably beacause the modem is not enabled correctly ??

    error: couldn't find bearer at '/org/freedesktop/ModemManager1/Bearer/0': 'not found in any modem'
  • From here everything is mostly documented in this Article

  • ...

Please comment your findings, I will check an put them in the link list
Thanks in advance for any help!

Re: HOWTO - Mobile Broadband - Fibocom L860-GL - xmm 7560

The forum isn't  the correct place for this.

Please use the relevant Talk pages on the wiki for gathering suggestions.


No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: HOWTO - Mobile Broadband - Fibocom L860-GL - xmm 7560

Thanks @esemeniuc,
I will add the links to the list.
Also I am finishing the structured configuration notes as soon as I have a couple of minutes.
A script is probably needed to do the enabling of the modem, unblocking the radio, and maybe do the FCC unlock after each reboot or wake-up from suspend. So there are a lot of things to cause the error.
