Working modem?

[dcinoz]

AT command for network registration but for me it just answers '':

Code:

mmcli -m any --command='AT+CREG'

A lot easier and verbose (works for Mobian):

Code:

sudo journalctl --since "5 minutes ago" | grep ModemManager

or

Code:

sudo journalctl -b

since boot for all messages.

You will see e.g.:

Code:

ModemManager[435]: <info>  [modem8] 3GPP registration state changed (registering -> home)
ModemManager[435]: <info>  [modem8] state changed (enabled -> registered)

and when I turn data on:

Code:

ModemManager[435]: <info>  [modem8] simple connect started...
ModemManager[435]: <info>  [modem8] simple connect state (4/8): wait to get fully enabled
ModemManager[435]: <info>  [modem8] simple connect state (5/8): register
ModemManager[435]: <info>  [modem8] simple connect state (6/8): bearer
ModemManager[435]: <info>  [modem8] simple connect state (7/8): connect
ModemManager[435]: <info>  [modem8] state changed (registered -> connecting)
ModemManager[435]: [/dev/cdc-wdm0] Allocating new client ID...
ModemManager[435]: [/dev/cdc-wdm0] Registered 'wds' (version 1.67) client with ID '17'
ModemManager[435]: <info>  [modem8/bearer2] QMI IPv4 Settings:
ModemManager[435]: <info>  [modem8/bearer2]     address: 10.70.25.25/30
ModemManager[435]: <info>  [modem8/bearer2]     gateway: 10.70.25.26
ModemManager[435]: <info>  [modem8/bearer2]     DNS #1: 10.5.195.164

ModemManager[435]: <info>  [modem8/bearer2]        MTU: 1460

and when I turn data off:

Code:

ModemManager[435]: <info>  [modem8] state changed (connected -> disconnecting)
ModemManager[435]: <info>  [modem8] state changed (disconnecting -> registered)
ModemManager[435]: <info>  [modem8/bearer2] connection #1 finished: duration 472s, tx: 236 bytes, rx :0 bytes

For Manjaro Plasma Mobile using ofonod / ofonoctl, see https://forum.pine64.org/showthread.php?tid=13213

You can use:

Code:

sudo systemctl -b

and you will see logs from:
eg25manager
pinephone-modem-setup.sh
manjaro:modem-setup
NetworkManager
ofonod
ofonoctl

Code:

sudo systemctl -b | grep NetworkManager

or

Code:

sudo systemctl -b | grep modem

will give you good info

e.g.

Code:

NetworkManager[3754]: <info>  [1614200469.7254] modem["quectelqmi_0"]: modem state changed, 'searching' --> 'registered' (reason: modem ready)
NetworkManager[3754]: <info>  [1614200470.0141] modem-ofono[quectelqmi_0]: Attached true -> false
NetworkManager[3754]: <info>  [1614200470.0143] modem-ofono[quectelqmi_0]: 'Attached': false 'Online': true 'IMSI': 505015601536136
NetworkManager[3754]: <info>  [1614200470.0143] modem["quectelqmi_0"]: modem state changed, 'registered' --> 'searching' (reason: modem searching)
NetworkManager[3754]: <info>  [1614200470.5266] modem-ofono[quectelqmi_0]: Attached false -> true
NetworkManager[3754]: <info>  [1614200470.5268] modem-ofono[quectelqmi_0]: 'Attached': true 'Online': true 'IMSI': 505015601536136

You have the ofono commands in the link I posted above:

Code:

ofonoctl list

to check registration.

Code:

ofonoctl wan

for wwan info.

To get the IP / gateway / route assigned

Code:

sudo ofonoctl wan --connect

Code:

ip a

and

Code:

ip r

to see the IP address and routes.

NOTE currently WWAN DEFAULT ROUTE HAS PRIORITY over Wifi so BEWARE.
And the Mobile Data toggle in the settings does not work (not for several of us anyway).

So to turn off mobile data delete the wwan0 ip address

Code:

sudo ip a del <ip_address/xx> dev wwan0
