org.freedesktop.ModemManager1.Modem.Simple — The ModemManager Simple interface.

Methods

Connect    (IN  a{sv} properties,
            OUT o     bearer);
Disconnect (IN  o     bearer);
GetStatus  (OUT a{sv} properties);

Description

The Simple interface allows controlling and querying the status of Modems.

This interface will only be available once the modem is ready to be registered in the cellular network. 3GPP devices will require a valid unlocked SIM card before any of the features in the interface can be used.

Method Details

The Connect() method

Connect (IN  a{sv} properties,
         OUT o     bearer);

Do everything needed to connect the modem using the given properties.

This method will attempt to find a matching packet data bearer and activate it if necessary, returning the bearer's IP details. If no matching bearer is found, a new bearer will be created and activated, but this operation may fail if no resources are available to complete this connection attempt (ie, if a conflicting bearer is already active).

This call may make a large number of changes to modem configuration based on properties passed in. For example, given a PIN-locked, disabled GSM/UMTS modem, this call may unlock the SIM PIN, wait for network registration (or force registration to a specific provider), create a new packet data bearer using the given "apn", and connect that bearer.

The list of allowed properties includes all the ones defined in the bearer properties plus these additional ones that are only applicable to this method, and only to 3GPP (GSM/UMTS/LTE/5GNR) devices:

`"pin"`	SIM-PIN unlock code, given as a string value (signature `"s"`).
`"operator-id"`	ETSI MCC-MNC of a network to force registration with, given as a string value (signature `"s"`).

There are no settings specific to this call that would apply to 3GPP2 (CDMA/EVDO) devices.

Since: 1.0

`IN a{sv} properties`:	Dictionary of properties needed to get the modem connected.
`OUT o bearer`:	On successful connect, returns the object path of the connected packet data bearer used for the connection attempt.

The Disconnect() method

Disconnect (IN  o bearer);

data bearer, while if "/" (ie, no object given) this method will disconnect all active packet data bearers.

Disconnect an active packet data connection.

Since: 1.0

IN o bearer:

If given this method will disconnect the referenced packet

The GetStatus() method

GetStatus (OUT a{sv} properties);

Get the general modem status.

The predefined common properties returned are:

`"state"`	A MMModemState value specifying the overall state of the modem, given as an unsigned integer value (signature `"u"`).
`"signal-quality"`	Signal quality value, given only when registered, as unsigned integer value and an additional boolean value indicating if the value was recently taken. (signature `"(ub)"`).
`"current-bands"`	List of MMModemBand values, given only when registered, as a list of unsigned integer values (signature `"au"`).
`"access-technologies"`	A MMModemAccessTechnology value, given only when registered, as an unsigned integer value (signature `"u"`).
`"m3gpp-registration-state"`	A MMModem3gppRegistrationState value specifying the state of the registration, given only when registered in a 3GPP network, as an unsigned integer value (signature `"u"`).
`"m3gpp-operator-code"`	Operator `MCC-MNC`, given only when registered in a 3GPP network, as a string value (signature `"s"`).
`"m3gpp-operator-name"`	Operator name, given only when registered in a 3GPP network, as a string value (signature `"s"`).
`"cdma-cdma1x-registration-state"`	A MMModemCdmaRegistrationState value specifying the state of the registration, given only when registered in a CDMA1x network, as an unsigned integer value (signature `"u"`).
`"cdma-evdo-registration-state"`	A MMModemCdmaRegistrationState value specifying the state of the registration, given only when registered in a EV-DO network, as an unsigned integer value (signature `"u"`).
`"cdma-sid"`	The System Identifier of the serving network, if registered in a CDMA1x network and if known. Given as an unsigned integer value (signature `"u"`).
`"cdma-nid"`	The Network Identifier of the serving network, if registered in a CDMA1x network and if known. Given as an unsigned integer value (signature `"u"`).

Since: 1.0
