## Methods

    List   (OUT s      selected,

## Description

This interface provides access to perform different firmware-related operations in the modem, including listing the available firmware images in the module and selecting which of them to use.

This interface does not provide direct access to perform firmware updates in the device. Instead, it exposes information about the expected firmware update method as well as method-specific details required for the upgrade to happen. The actual firmware upgrade may be performed via the Linux Vendor Firmware Service and the fwupd daemon.

This interface will always be available as long a the modem is considered valid.

## Method Details

### The `List()` method

    List (OUT s      selected,
          OUT aa{sv} installed);

List installed firmware images.

Firmware slots and firmware images are identified by arbitrary opaque strings.

Firmware images are represented as dictionaries of properties. Certain properties are pre-defined, and some are required:

`"image-type"` | (Required) Type of the firmware image, given as a MMFirmwareImageType value (signature `"u"`). Firmware images of type MM_FIRMWARE_IMAGE_TYPE_GENERIC will only expose only the mandatory properties.
`"unique-id"` | (Required) A user-readable unique ID for the firmware image, given as a string value (signature `"s"`).
`"gobi-pri-version"` | (Optional) The version of the PRI firmware image, in images of type MM_FIRMWARE_IMAGE_TYPE_GOBI, given as a string value (signature `"s"`).
`"gobi-pri-info"` | (Optional) Additional information of the PRI image, in images of type MM_FIRMWARE_IMAGE_TYPE_GOBI, given as a string value (signature `"s"`).
`"gobi-boot-version"` | (Optional) The boot version of the PRI firmware image, in images of type MM_FIRMWARE_IMAGE_TYPE_GOBI, given as a string value (signature `"s"`).
`"gobi-pri-unique-id"` | (Optional) The unique ID of the PRI firmware image, in images of type MM_FIRMWARE_IMAGE_TYPE_GOBI, given as a string value (signature `"s"`).
`"gobi-modem-unique-id"` | (Optional) The unique ID of the Modem firmware image, in images of type MM_FIRMWARE_IMAGE_TYPE_GOBI, given as a string value (signature `"s"`).

Since: 1.0

`OUT s `selected``: | The unique name of the selected firmware image, or the empty string if no image is selected.
`OUT aa{sv} `installed``: | An array of dictionaries containing the properties of the installed firmware images.

### The `Select()` method

    Select (IN  s uniqueid);

Selects a different firmware image to use, and immediately resets the modem so that it begins using the new firmware image.

The method will fail if the identifier does not match any of the names returned by `List()`, or if the image could not be selected for some reason.

Installed images can be selected non-destructively.

Since: 1.0

`IN s `uniqueid``: | The unique ID of the firmware image to select.

## Property Details

### The "UpdateSettings" property

    UpdateSettings  readable   (ua{sv})

Detailed settings that provide information about how the module should be updated.

The settings are given as a bitmask of MMModemFirmwareUpdateMethod values specifying the type of firmware update procedures expected followed by a dictionary that includes other parameters applicable to the specific methods reported.

| The following settings are mandatory as long as the reported update method is not MM_MODEM_FIRMWARE_UPDATE_METHOD_NONE.
`"device-ids"` | (Required) This property exposes the list of device IDs associated to a given device, from most specific to least specific. (signature `'as'`). E.g. a list containing: `"USB\VID_413C&PID_81D7&REV_0001"`, `"USB\VID_413C&PID_81D7"` and `"USB\VID_413C"`.
`"version"` | (Required) This property exposes the current firmware version string of the module. If the module uses separate version numbers for firmware version and carrier configuration, this version string will be a combination of both, and so it may be different to the version string showed in the "Revision" property. (signature `'s'`)

MM_MODEM_FIRMWARE_UPDATE_METHOD_FASTBOOT | Devices supporting the fastboot firmware update method require exposing the following additional settings:
`"fastboot-at"` | (Required) This property exposes the AT command that should be sent to the module to trigger a reset into fastboot mode (signature `'s'`)

Since: 1.10
