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

  -------------------------------

• 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!

The forum isn't  the correct place for this.

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

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.
