Hi, did I get it right the tool generates a VPN tunnel on the phone side? Then this might not fall under Android's category of a connected "wifi" or "flight mode". Usually Android sees tethering as hotspot, VPN inherits Android's connection guess of the underlying connection. I suspect the problem here is, Android does not report any connection type to our Syncthing App because your just using "usb software protocol / adb" as transport which is not an IP/PPP based connection type the OS recognizes.

Hi CatFriend1.

You are correct.  It does appear to generate the VPN. This does make sense; VPN is like it's own "cord" to the Internet (like the ethernet cable, but it is through USB; independent of any radio-like communications. Plus this is a reverse-tethering. The desktop provides the Internet connection.

As for gnirehtet itself, I'm unsure if it is following the IP/PPP protocol. -- Sent with Tutanota, the secure & ad-free mailbox: https://tutanota.com
