[Networkmanager] Creating, enabling, disabling wifi access point using libnm-glib

[VT102]

Ben,

Thank you for taking the time to respond. I have been able to get some C code working to create a hot spot on the wlan0 device, however it is not clear to me how to close/delete the connection from the nmlib API.

I see that nmcli deletes connections using the nm_remote_connection_delete_aysnc api, however this does not work with the NMConnection that I created. Can you provide any guidance on this?


Thank you,
Greg
