Nice to hear that you got this working.

This is required if you use ap_scan=2 mode, but it should not be
required in ap_scan=1 (i.e., wpa_supplicant uses scan results to select
an AP).

The proto option is used to list the allowed protocol versions and if
scan results can be used, wpa_supplicant will select one of the allowed
protocols. RSN/WPA2 is selected if it is allowed (the default
configuration) and the AP is advertising support for WPA2 (i.e.,
includes an RSN IE in the Beacon).

This works with Host AP driver when using ap_scan=1 (default). Please
send a debug log from wpa_supplicant if you cannot get this working.
