Currently, when SIM hot swap fails in either mm-iface or plugin, the ModemManager still opens ports context and prints a message saying that SIM hot swap is supported and that it's waiting for SIM insertion, instead of clearly saying that SIM hot swap is not working. This patch: 1. introduces a new property MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED which is FALSE by default and set to TRUE only when setup_sim_hot_swap_finish() succeded. 2. subordinates the completion of SIM hot swap setup (in mm-broadband-modem) and the related messages to the the value of MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED Finally, this patch replaces the MBIM's sim_hot_swap_on private property with the new property MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED, since they have the same meaning.
ModemManager. ModemManager provides a unified high level API for communicating with mobile broadband modems, regardless of the protocol used to communicate with the actual device (Generic AT, vendor-specific AT, QCDM, QMI, MBIM...). Using. ModemManager is a system daemon and is not meant to be used directly from the command line. However, since it provides a DBus API, it is possible to use 'dbus-send' commands or the new 'mmcli' command line interface to control it from the terminal. The devices are queried from udev and automatically updated based on hardware events, although a manual re-scan can also be requested to look for RS232 modems. Implementation. ModemManager is a DBus system bus activated service (meaning it's started automatically when a request arrives). It is written in C, using glib and gio. Several GInterfaces specify different features that the modems support, including the generic MMIfaceModem3gpp and MMIfaceModemCdma which provice basic operations for 3GPP (GSM, UMTS, LTE) or CDMA (CDMA1x, EV-DO) modems. If a given feature is not available in the modem, the specific interface will not be exported in DBus. Plugins. Plugins are loaded on startup, and must implement the MMPlugin interface. It consists of a couple of methods which tell the daemon whether the plugin supports a port and to create custom MMBroadbandModem implementations. It most likely makes sense to derive custom modem implementations from one of the generic classes and just add (or override) operations which are not standard. There are multiple fully working plugins in the plugins/ directory that can be used as an example for writing new plugins. Writing new plugins is highly encouraged! The plugin API is open for changes, so if you're writing a plugin and need to add or change some public method, feel free to suggest it! License. The ModemManager and mmcli binaries are both GPLv2+. The libmm-glib library is LGPLv2+.
