Password for Hotspot or WiFi-Direct (if possible)

[bbx]

Hello, I'm interested in the ability to use Wiim Mini without a router because it is simply not available. I know that the access point of the device can be password protected, but not in this firmware. I would not like to use an open access point. Thus, it would be great to return this feature. I don't know if this device supports peer-to-peer networks, but wifi-direct would also be a good option. Thank you
