You also want to set the Interface object's 'ap_scan' variable to '2',
same as for adhoc mode.

But beyond that, it should just work if the driver supports AP mode.
What errors are you getting?  Can you share some supplicant debug logs?
You can run the supplicant with "-dddtu" arguments alone and that should
enable the dbus interface and provide verbose debugging output.
