Could not acquire the 'org.freedesktop.ModemManager1' service name

[Jan Graczyk]

Hello Aleksander,

Thank you for your response. I have actually stopped running Modem Manger and then I have issued the command ModemManager --debug. This time the service name was acquired. However I have got another problem. The mm-base-manager.c:314 reports error device added(): (tty/ttymxc2): port's parent platform driver is not whitelisted. Do you know the solution for this problem? Thank you for your support.

Best Regards,
Jan Graczyk

When I try to run mmcli -L or ModemManager –debug the message “Could not acquire the 'org.freedesktop.ModemManager1' service name” is showing up. How to connect my Linux modem device /dev/ttymxc2 to ModemManger? I appreciate very much help from you.


Do you have the DBus daemon running in your system? ModemManager will grab the "org.freedesktop.ModemManager1" name in the system bus exposed by DBus; mmcli talks to ModemManager through that bus.
