		uint	timeout )

Definition at line 384 of file modem.cpp.

createBearer()

QDBusPendingReply< QDBusObjectPath > Modem::createBearer

(

const ModemManager::BearerProperties &

bearerProperties

Create a new packet data bearer using the given characteristics.

This request may fail if the modem does not support additional bearers, if too many bearers are already defined, or if properties are invalid.

Definition at line 289 of file modem.cpp.

currentBands()

QList< MMModemBand > Modem::currentBands

(

)

const

Returns

List of MMModemBand values, specifying the radio frequency and technology bands the device is currently using when connecting to a network.

It must be a subset of supportedBands()

Definition at line 546 of file modem.cpp.

currentCapabilities()

ModemManager::Modem::Capabilities Modem::currentCapabilities

(

)

const

Returns

QFlags of MMModemCapability values, specifying the generic family of access technologies the modem currently supports without a firmware reload or reinitialization.

Definition at line 402 of file modem.cpp.

currentModes()

ModemManager::CurrentModesType Modem::currentModes

(

)

const

Returns

A pair of MMModemMode values, where the first one is a bitmask specifying the access technologies (eg 2G/3G/4G) the device is currently allowed to use when connecting to a network, and the second one is the preferred mode of those specified as allowed.

The pair must be one of those specified in supportedModes()

Definition at line 534 of file modem.cpp.

deleteBearer()

QDBusPendingReply< void > Modem::deleteBearer

(

const QString &

bearer

)

Delete an existing packet data bearer.

If the bearer is currently active and providing packet data server, it will be disconnected and that packet data service will terminate.

Parameters

bearer

path to the bearer to delete

Definition at line 316 of file modem.cpp.

device()

QString Modem::device

(

)

const

Returns

The physical modem device reference (ie, USB, PCI, PCMCIA device), which may be dependent upon the operating system.

In Linux for example, this points to a sysfs path of the usb_device object.

Definition at line 444 of file modem.cpp.

deviceIdentifier()

QString Modem::deviceIdentifier

(

)

const

Returns

A best-effort device identifier based on various device information like model name, firmware revision, USB/PCI/PCMCIA IDs, and other properties.

This ID is not guaranteed to be unique and may be shared between identical devices with the same firmware, but is intended to be "unique enough" for use as a casual device identifier for various user experience operations.

This is not the device's IMEI or ESN since those may not be available before unlocking the device via a PIN.

Definition at line 438 of file modem.cpp.

drivers()

QStringList Modem::drivers

const

Returns

The Operating System device drivers handling communication with the modem hardware.

Definition at line 450 of file modem.cpp.

)

const

Returns

The maximum number of active packet data bearers the modem supports.
