Hi, For my iOS app, I want to temporarirly connect to a in-house Wifi accessory. The iOS app will exchange some messages to configure the accessory and Wifi accessory does not need a connection to the internet. Based on the other post, NEHotspotConfiguration can be used to programmatically connect to a wifi network. However, iOS ask the authorization "Wants to Join Wi-Fi Network". I have following questions: Can we Wireless Accessory Configuration (WAC) for the same interaction? And in this case, can we silently connect to the accessory using Wifi without user having to authorize the connection? If WAC is used for this application, do we have to go through MFi certification? And what is estimated cost for this certification? Do we pay a one time fee or per device/app installation fee? The device is usb peripheral with a built-in wifi module. Thanks for the clarification
