.SH NAME
mmcli \- Control and monitor the ModemManager
.SH SYNOPSIS
\fBmmcli\fR [\fIOPTION\fR...]
.SH DESCRIPTION
ModemManager is a DBus-powered Linux daemon which provides a unified
high level API for communicating with (mobile broadband) modems. It
acts as a standard RIL (Radio Interface Layer) and may be used by
different connection managers, like NetworkManager. Thanks to the
built-in plugin architecture, ModemManager talks to very different
kinds of modems with very different kinds of ports. In addition to the
standard AT serial ports, Qualcomm-based QCDM and QMI ports are also
supported.

.SH MANAGER OPTIONS
.TP
.B \-B, \-\-get\-daemon\-version
Retrieve the version of the currently running ModemManager daemon.
.TP
.B \-G, \-\-set\-logging=[ERR|WARN|INFO|DEBUG]
Set the logging level in ModemManager daemon. For debugging information you can
supply \fBDEBUG\fR. Each value above \fBDEBUG\fR provides less detail. In most
cases \fBERR\fR (for displaying errors) are the important messages.
The default mode is \fBERR\fR.
.TP
.B \-L, \-\-list\-modems
List available modems.
.TP
.B \-M, \-\-monitor\-modems
List available modems and monitor modems added or removed.
.TP
.B \-S, \-\-scan-modems
Scan for any potential new modems. This is only useful when expecting pure
RS232 modems, as they are not notified automatically by the kernel.
.TP
.B \-I, \-\-inhibit\-device=[UID]
Inhibit the specific device from being used by ModemManager. The \fBUID\fR
that should be given is the value of the \fBDevice\fR property exposed by
a given modem (i.e. equal to the \fBID_MM_PHYSDEV_UID\fR if one set, or
otherwise equal to the full device sysfs path).
This command will not exit right away, as that would implicitly remove the
inhibition. The user must make sure to stop the mmcli process hitting Ctrl+C
in order to un-inhibit the device.
When a device is inhibited via this method, ModemManager will disable the modem
(therefore stopping any ongoing connection) and will no longer use it until it
is uninhibited.
.TP
.B \-\-report\-kernel\-event=['KEY1=VALUE1,KEY2=VALUE2,...']
Manually report kernel events, instead of relying on udev (e.g. if the daemon
is running with \fB\-\-no\-auto\-scan\fR or if the system was built without udev
support).
The supported \fBKEY\fRs are:
.RS 9
.TP
\fB'action'\fR
Action to report, one of 'add' or 'remove'. Required.
.TP
\fB'subsystem'\fR
Subsystem of the specific port being reported, e.g. 'tty' (for serial ports),
'net' (for network interfaces), or 'usbmisc' (for cdc-wdm ports)..
.TP
\fB'name'\fR
Name of the port being reported, e.g. 'ttyACM0', 'wwan0' or 'cdc-wdm0'.
.TP
\fB'uid'\fR
The specific UID of the device, equivalent to the \fBID_MM_PHYSDEV_UID\fR udev
tag. All ports reported with the same 'UID' value will be considered part of the
same device, which may be useful for e.g. modems with multiple platform TTYs.
.RE
.TP
.B \-\-report\-kernel\-event\-auto\-scan
When built with udev support but the daemon is running with
\fB\-\-no\-auto\-scan\fR, this method may be used to automatically report kernel
events based on udev.
This command will not exit right away. The user must make sure to stop the mmcli
process hitting Ctrl+C in order to stopping monitoring for new events.
.SH COMMON OPTIONS
All options below take a \fBPATH\fR or \fBINDEX\fR argument. If no action is
provided, the default information about the modem, bearer, etc. is
shown instead.
The \fBPATH\fR and \fBINDEX\fR are created automatically when the
modem is plugged in. They can be found using \fBmmcli \-L\fR. This
produces something like (for modems only):
.RS 7
Found 1 modems:
/org/freedesktop/ModemManager1/Modem/\fB4\fR
.RE
In this case, the \fBINDEX\fR is \fB4\fR and the \fBPATH\fR is the entire string above.
However, for the bearers, SIMs and SMS cases, the \fBPATH\fR is
slightly different. The \fIModem\fR is replaced with the object name
in use, like \fIBearer\fR. For example:
.RS 7
/org/freedesktop/ModemManager1/\fIBearer\fR/4
.RE
.TP
.B \-m, \-\-modem=[PATH|INDEX]
Specify a modem.
.TP
.B \-b, \-\-bearer=[PATH|INDEX]
Specify a bearer.
.TP
.B \-i, \-\-sim=[PATH|INDEX]
Specify a SIM card.
.TP
.B \-s, \-\-sms=[PATH|INDEX]
Specify an SMS.
.SH MODEM OPTIONS
All of the modem options below make use of the \fB\-\-modem\fR or
\fB\-m\fR switch to specify the modem to act on.
Some operations require a \fBMODE\fR. \fBMODE\fR can be any
combination of the modes actually supported by the modem. In the
perfect case, the following are possible:
.Bd -literal -compact
\fB'2G'\fR - 2G technologies, e.g. EDGE, CDMA1x
\fB'3G'\fR - 3G technologies, e.g. HSPA, EV-DO
\fB'4G'\fR - 4G technologies, e.g. LTE
\fB'ANY'\fR - for all supported modes.
.Ed
.TP
.B \-w, \-\-monitor\-state
Monitor the state of a given modem.
.TP
.B \-e, \-\-enable
Enable a given modem.
This powers the antenna, starts the automatic registration process and
in general prepares the modem to be connected.
.TP
.B \-d, \-\-disable
Disable a given modem.
This disconnects the existing connection(s) for the modem and puts it
into a low power mode.
.TP
.B \-r, \-\-reset
Resets the modem to the settings it had when it was power cycled.
.TP
.B \-\-factory\-reset=CODE
Resets the modem to its original factory default settings.
The \fBCODE\fR provided is vendor specific. Without the correct vendor
code, it's unlikely this operation will succeed. This is not a common
user action.
.TP
.B \-\-command=COMMAND
Send an AT \fBCOMMAND\fR to the given modem. For example,
\fBCOMMAND\fR could be 'AT+GMM' to probe for phone model information. This
operation is only available when ModemManager is run in debug mode.
.TP
.B \-\-list\-bearers
List packet data bearers that are available for the given modem.
.TP
.B \-\-create\-bearer=['KEY1=VALUE1,KEY2=VALUE2,...']
Create a new packet data bearer for a given modem. The \fBKEY\fRs and
some \fBVALUE\fRs are listed below:
.RS 9
.TP
\fB'apn'\fR
Access Point Name. Required in 3GPP.
.TP
\fB'ip-type'\fR
Addressing type. Given as a MMBearerIpFamily value (e.g. 'ipv4', 'ipv6', 'ipv4v6'). Optional in 3GPP and CDMA.
.TP
\fB'allowed-auth'\fR
Authentication method to use. Given as a MMBearerAllowedAuth value (e.g. 'none|pap|chap|mschap|mschapv2|eap'). Optional in 3GPP.
.TP
\fB'user'\fR
User name (if any) required by the network. Optional in 3GPP.
.TP
\fB'password'\fR
Password (if any) required by the network. Optional in 3GPP.
.TP
\fB'allow-roaming'\fR
Flag to tell whether connection is allowed during roaming, given as a boolean value (i.e 'yes' or 'no'). Optional in 3GPP.
.TP
\fB'rm-protocol'\fR
Protocol of the Rm interface, given as a MMModemCdmaRmProtocol value (e.g. 'async', 'packet-relay', 'packet-network-ppp', 'packet-network-slip', 'stu-iii'). Optional in CDMA.
.TP
\fB'number'\fR
Telephone number to dial. Required in POTS.
.RE
.TP
.B \-\-delete\-bearer=[PATH|INDEX]
Delete bearer from a given modem.
.TP
.B \-\-set\-allowed\-modes=[MODE1|MODE2|...]
Set allowed modes for a given modem. For possible modes, see the
beginning of this section.
.TP
.B \-\-set\-preferred\-mode=MODE
Set the preferred \fBMODE\fR for the given modem. The \fBMODE\fR
\fIMUST\fR be one of the allowed modes as set with the
\fB\-\-set\-allowed\-modes\fR option. Possible \fBMODE\fR arguments
are detailed at the beginning of this section.
.TP
.B \-\-set\-current\-bands=[BAND1|BAND2|...]
Set bands to be used for a given modem. These are frequency ranges
the modem should use. There are quite a number of supported bands and
listing them all here would be quite extensive. For details, see the
MMModemBand documentation.
An example would be: 'egsm|dcs|pcs|g850' to select all the GSM
frequency bands.
.TP
.B \-\-inhibit
Inhibit the specific modem from being used by ModemManager. This method
is completely equivalent to \fB\-\-inhibit\-device\fR, with the only
difference being that in this case, the modem must be managed by the daemon
at the time the inhibition is requested.
This command will not exit right away, as that would implicitly remove the
inhibition. The user must make sure to stop the mmcli process hitting Ctrl+C
in order to un-inhibit the device.
When a device is inhibited via this method, ModemManager will disable the modem
(therefore stopping any ongoing connection) and will no longer use it until it
is uninhibited.

.SH EXAMPLES
.SS Send the PIN to the SIM card
You'll need first to know which the proper path/index is for the SIM in your
modem:
.Bd -literal -compact
$ mmcli -m 0 -K | grep "modem.generic.sim" | awk -F ": " '{ print $2 }'
/org/freedesktop/ModemManager1/SIM/0
.Ed
And after that, you can just use the SIM index:
.Bd -literal -compact
$ sudo mmcli -i 0 --pin=1234
successfully sent PIN code to the SIM
.Ed
.SS Simple connect and disconnect
You can launch the simple connection process like:
.Bd -literal -compact
$ sudo mmcli -m 0 --simple-connect="pin=1234,apn=internet"
successfully connected the modem
.Ed
Then, you can disconnect it like:
.Bd -literal -compact
$ sudo mmcli -m 0 --simple-disconnect
successfully disconnected all bearers in the modem
.Ed
.SS 3GPP network scan
Scanning for 3GPP networks may really take a long time, so a specific timeout
must be given:
.Bd -literal -compact
$ sudo mmcli -m 0 --3gpp-scan --timeout=300
---------------------
3GPP scan | networks: 21403 - Orange SP (gprs, unknown)
| 21407 - Movistar (gprs, unknown)
| 21404 - YOIGO (gprs, unknown)
| 21401 - vodafone ES (gprs, unknown)
.Ed
.SS Creating a new SMS message & storing it
Using the “sm” (SIM), you can do this using:
.Bd -literal -compact
$ sudo mmcli -m 0 --messaging-create-sms="text='Hello world',number='+1234567890'"
Successfully created new SMS:
/org/freedesktop/ModemManager1/SMS/21 (unknown)
$ sudo mmcli -s 21 --store-in-storage="sm"
successfully stored the SMS
$ sudo mmcli -s 21

.SS Sending binary SMS messages from files
As you can see below, the important part is the
\fB\-\-messaging\-create\-sms\-with\-data\fR and the \fBPATH\fR provided.
.Bd -literal -compact
$ sudo mmcli -m 0 \\
--messaging-create-sms="number='+1234567890'" \\

.SS GPS location status
You first need to check whether the modem has GPS-specific location
capabilities. Note that we’ll assume the modem is exposed as index 0;
if you have more than one modem, just use --list-modems to check the
proper modem index:
.Bd -literal -compact
$ mmcli -m 0 --location-status
----------------------------
Location | capabilities: 3gpp-lac-ci, gps-raw, gps-nmea
| enabled: none
| signals: no
.Ed
The output says that the modem supports 3GPP Location area code/Cell
ID, GPS raw and GPS-NMEA location sources. None is enabled yet, as we
didn’t enable the modem, which we can do issuing:
.Bd -literal -compact
$ sudo mmcli -m 0 --enable
successfully enabled the modem
$ mmcli -m 0 --location-status
----------------------------
Location | capabilities: 3gpp-lac-ci, gps-raw, gps-nmea

.SS GPS location technology enabling
We can start the GPS engine by enabling the RAW or NMEA GPS location sources:
.Bd -literal -compact
$ sudo mmcli -m 0 \\
--location-enable-gps-raw \\
--location-enable-gps-nmea
successfully setup location gathering
.Ed
If we do check again the status, we’ll see the GPS-specific locations are enabled:
.Bd -literal -compact
$ mmcli -m 0 --location-status

Location | capabilities: 3gpp-lac-ci, gps-raw, gps-nmea

.SS GPS location retrieval
You can query all location information at the same time with a single command.
If any of the specific outputs is not available, the corresponding section will
be omitted from the output.

.SS A-GPS support
If A-GPS is enabled before starting the GPS engine, and if a data connection
is available in the modem, the configured SUPL servers may be used to obtain
a faster initial position fix.
Note that the GPS engine will not be started when just A-GPS capability is
enabled. An explicit output (RAW or NMEA) is required to be enabled in order
to start the GPS engine.

.SS Injecting assistance data
If the modem device does not have an ongoing connection (e.g. no mobile network
coverage) but the system has other means to access the Internet (e.g. WiFi), the
user may be able to download location assistance data and inject it in the
module.
E.g. If the device supports XTRA assistance data, the user may download it from
one of the servers listed by ModemManager and manually inject it afterwards. The
XTRA assistance data is usually valid for several days.

.SS Key-Value output
Writing shell scripts that use mmcli to perform operations with the
modem is easy when using the \fB\-\-output\-keyvalue\fR option. For
example, you could gather all the main status information of the modem
with a single call and then parse it to read single fields:
.Bd -literal -compact
$ STATUS=$(mmcli -m 0 --output-keyvalue)
$ echo "${STATUS}" | grep "modem.generic.state " | awk -F ": " '{ print $2 }'
failed
$ echo "${STATUS}" | grep "modem.generic.state-failed-reason " | awk -F ": " '{ print $2 }'
