A few examples of functionality offered by ModemManager are: * initialisation of the modem * connecting to the Internet * sending/receiving SMS * firmware upgrades for select QMI-based modems. ===== Installing ===== In ''menuconfig'', ModemManager is located under the Network section. ===== Kernel modules ===== You probably need to include the kernel module for your modem in your firmware image, or on running firmware via [[:docs:guide-user:additional-software:opkg]]. Common ones which should get most modems working to some extent are: <code>opkg update && opkg install kmod-usb-serial kmod-usb-net kmod-usb-serial-wwan kmod-usb-serial-option kmod-usb-net-qmi-wwan kmod-usb-net-cdc-mbim</code> ===== MBIM Support ===== ModemManager supports MBIM modems. You can include MBIM support by selecting it under the Configuration section in ModemManager's ''menuconfig'' entry. ===== QMI Support ===== ModemManager supports QMI modems. You can include QMI support by selecting it under the Configuration section in ModemManager's ''menuconfig'' entry. ===== Use ===== ModemManager abstracts the configuration of your modems into standard Linux network interfaces. The example below illustrates a typical configuration: **/etc/config/network** <code> config interface 'broadband' option device '/sys/devices/platform/soc/20980000.usb/usb1/1-1/1-1.2/1-1.2.1' option proto 'modemmanager' option apn 'ac.vodafone.es' option username 'vodafone' option password 'vodafone' option pincode '7423' option lowpower '1' </code> The available options are ^ option^type^required^description^ |device|string|X|Full sysfs path of the device, for example ''/sys/devices/platform/soc/20980000.usb/usb1/1-1/1-1.2/1-1.2.1''.
