I installed on RPI zero W a ad hoc wifi network, through this github project: https://github.com/simondlevy/RPiAdHocWiFi
I works perfectly with my mac, and my iphone, so I can connect correctly (please note that I see the wifi network as a "device" in the network list).
The pb I have is that I cannot see and connect from an Android phone. With a sniffing app I can see the network, but in the network settings the essid doesnt even show up.
Any idea on what to test/analyze?
Thanks a lot!
