Could be the case; when I implemented it I was using an Intel-based TOBY-L4, which did support both reading and setting. > The TS 27.007 command > corresponding to the above AT+QNVFW command seems to be AT+CEUS > which typically isn't implemented at all. > > However NASSetSystemSelectionPref TLV 0x21 which is already part > of the original Gobi API usually seems to work quite well. > Oh, thanks for the hint! So that would be qmi_message_nas_set_system_selection_preference_input_set_usage_preference() with QMI_NAS_USAGE_PREFERENCE_DATA_CENTRIC. https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/blob/main/data/qmi-service-nas.json#L1530 I think we could update ModemManager to support that. Looks like AT+CEUS and the QMI variant are a subset of what AT+CEMODE allows, right? Or am I missing something? -- Aleksander https://aleksander.es
