(Apologies for the top post... blame it on outlook)

I added lines starting with # to indicate which call failed, and which succeeded.

I'll try to get a code snippet.

This would indicate the partial connection dict you're sending to NetworkManager as part of the 
AddAndActivateConnection call doesn't have all the required properties.

What NM needs here is either the object path to an existing AP that it can pull the SSID and security 
settings from, or you need to specify those manually (which you must do here because you're doing a hotspot).
 Apparently it's not getting that from the D-Bus method call, or there's a bug in the code...

Can you share sanitized/condensed code that shows how you're calling AddAndActivate?
