Maybe this belongs under compatibility but I just wanted to let people know Google has made some changes to remove features like “manage devices” under the hotspot menu. This is bad for Pi setups or other headless devices. Normally you are allowed to view IP and MAC addresses when making new connections with the phone. You can’t set static IP addresses with your phone either. I just found out that the Pixel type phones have a different Android version (I mean software build) than Samsung or Motorola.
Maybe there is an app that can scan IP’s handed out by your phone? It would have to scan over it’s own network. Wireshark would be nice but I don’t think they have an app for that. I suspect iphones have been this private for a while but now google is doing the same. For Pi users that are going headless I would suggest staying away from Pixel phones. I have an Android version 11 on a 2021 Motorola and I still have all the awesome features.
Also why does the Volumio app not work without internet wifi? Instead of just a private Lan connection?
