The DW5821e will expose four different device IDs: These device IDs are the ones that fwupd will use to build the GUIDs required to match a given device to a given firmware package.

The вЂњ device-idsвЂќ field will include a list of strings providing the device IDs associated to the device, sorted from the most specific to the least specific.

These two fields are designed so that fwupd can fully rely on them during its operation: The list of settings provided in the dictionary contain the two mandatory fields required for all devices that support at least one firmware update method: вЂњdevice-idsвЂќ and вЂњversionвЂќ.

вЂњfastbootвЂќ would be used to perform the system upgrade by using an OTA update file, and вЂњqmi-pdcвЂќ would be used to install the per-carrier configuration files after the system upgrade has been done. In the case of the DW5821e, two update methods are reported in the bitmask: вЂњ fastbootвЂќ and вЂњ qmi-pdcвЂњ, because both are required to have a complete firmware upgrade procedure. The Firmware interface in the modem object exposed in DBus contains, since MM 1.10, a new UpdateSettings property that provides a bitmask specifying which is the expected firmware update method (or methods) required for a given module, plus a dictionary of key-value entries specifying settings applicable to each of the update methods. 1) ModemManager reports expected update methods, firmware version and device IDs

The firmware update integration between ModemManager and fwupd involves different steps, which IвЂ™ll try to describe here so that itвЂ™s clear how to add support for more devices in the future. There is no official firmware released in the LVFS (yet) but the setup is completely ready to be used, just waiting for Dell to publish an initial official firmware release. The firmware update process of this DW5821e module is integrated in your GNU/Linux distribution, since ModemManager 1.10.0 and fwupd 1.2.6. no additional drivers or connection managers required in Windows) and also provides all the features that QMI provides through QMI over MBIM operations. In Linux kernel based and Windows based systems, the MBIM mode is the default one, because it provides easy integration with the OS (e.g. This modem can work in either MBIM mode or QMI mode, and provides different USB layouts for each of the modes. The Dell Wireless 5821e module is a Qualcomm SDX20 based LTE Cat16 device.
