I am using Rpi 3 + NAVIO2 (emlid-raspbian-20170922.img.xz)
I have alreay made some changes to the system get intwifi0 as AP using:
I have inserted TP-Link TL-WN722N(EU) Ver 2.0 wifi dongle expecting it to connect to the network that I have spcified in wpa_supplicant file. That config worked with intwifi0 before I changed it to be access point.
