The SetInitialEpsBearerSettings() procedure does an implicit power down always before changing the settings, so that when powering up again (and re-registering to the network) the correct initial EPS bearer settings are used, see e.g. in the QMI implementation: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/blob/master/src/mm-broadband-modem-qmi.c#L8908 That means that you should be able to run the method at any time, there should be no need to e.g. disable + power down + enable before running SetInitialEpsBearerSettings(), that would be a bit strange as you would really be powering down twice. Can you retry your tests without the additional disable + power down + enable sequence? -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
