I just realized my question may not be clear.
Is it necessary to use the Access Point function to commission a network?
I can connect my Phone to my local network through an ipv4 address with wifi - the usual way.
The Rasberry Pi Border Router is connected via Ethernet to the same network.
The Raspberry Pi serves the OpenThread Border Router over a local ipv4 address.
Things appear to work well nominally so I am wondering if the Access Point is servine a second and necessary function. The Access Point is also the function I am having the most trouble with but that is a different story.
