Hi, while the script is not particularly elegant (e.g. it keeps polling whether the profile is fully activate), it should work fine in principle. It also succeeds to create a profile, but activation fails later on. This has nothing to do with D-Bus API. You can create the exact same profile with nmcli and encounter the same problem. What I mean, is that when I try `nmcli connection up MyAdhoc`, the activation also fails (just like with the python script). The question is, why it fails. But I don't know... General tip: enabling level=TRACE logging is helpful (see [1]). Also, check what is happening with `nmcli connection` and `nmcli device`.
