I just noticed that I was not using the most recent Broadcom wl driver - after 
compiling the most recent driver (6.30.223.141) things now work.

wpa_supplicant will connect manually without "ap_scan=2" and 
network-manager-applet will also connect.

 However, "nmcli con list id" still shows "hidden=no"
