At the moment there is no way to select the CID in ModemManager. MM selects an empty CID to use if the new APN settings don't exist already; and if they exist they will re-use the existing CID. It is true that playing around with CID=1 may not be a good idea in some modems, as that is the default context for the initial EPS bearer settings in some chipsets (IIRC the 3GPP default should have been CID=0). To try to solve this, we're working on giving the user the ability to manage connection profiles themselves, see https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/179 > I am also interested in how modem manager creates and manages the modem > context ? > This is just done during the connection attempt, based on the APN settings given by the user. MM just looks for them, and reuses them if found, or updates the next free CID with the new ones otherwise. What CID is in use has been hidden to the user of the MM API on purpose in the past; but since different modems treat specific CIDs in a special way, we're working on changing that, as said before. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
