That is not going to work. Let’s look at it this way:
www → phone’s mobile ( 4G / 5G ) (WAN)
phone’s WiFi set as hotspot → local network (LAN)
the phone hands out an IP to devices in the LAN i.e. the computer.
the phone cannot hand out IPs in the same network as it’s WAN connection, for obvious reasons.
What could work, is to have an extra SIM card, and a 4G/5G router. Then phone’s mobiile data can be off, both phone and computer connect to the router getting IPs in the same subnet. So will be able to see eachother.
I’m not sure what you mean by what isn’t going to work. A common wireless network will work to provide LAN connectivity, but if you mean to provide concurrent internet and LAN connectivity, then yes a 4G/ 5G mobile router with Wi-Fi is a good option, assuming that the OP has the budget to do so.
Problem is that the phone’s WiFi is “the router” in this case. It cannot connect to the same AP at the same time. So either the AP needs www access where phone is one of the devices in the network, or the phone is the AP where everything “behind” it is in the subnet, Phone cannot do both.
That’s not a problem in itself though. The Wi-Fi gateway interface is by definition on the same network. The inbuilt firewall effectively provides the isolation. It doesn’t have to be that way.
Android blocking KDE on hotspots, some phone do client separation, so you cannot access your phone from connected computers…
but if you on the same access point WLAN and the firewall port is open on the computer it works.
Just need to pair it and KDE needs access to the memory and open on the phone to receive files. the other ways round, from the phone to the PC is usually easier.
I use KDE connect with
iPAD OS, Linux, Windows, Android.
iPAD activate stage manager and put it as a window in the background of the current destop.
Android open KDE settings and on the KDE open KDE connect from the task symbols, often they want to be opened at the same time, only then they show up
To use the Internet, I turn on the hotspot button on my phone.
If I turn on the WiFi button on my phone, the hotspot turns off automatically. Of course, it shows no networks available.
I would be okay with, if I’m transferring files, I don’t’ have access to the Internet during that time.
I would think this would be a more than rare need. Guess not. Imagine I’m somewhere with no Internet, no network, just a phone out of range of cell towers and a computer. Is there a way to transfer files across? I think this could very well happen, that someone goes to a meeting, with no network, with their phone and laptop to do a presentation, and need to transfer a forgotten file from phone to their laptop.
Or how about, two laptop computers with Wireless capabilities in the middle of nowhere. I think that’d be the same situation, no?
Can either the phone and laptop, or the two laptops be able to use KDE Connect? Create a network between them? Without purchasing anything.
Yes, there is WiFi Direct (P2P). To my best knowledge iPhone while supporting it does expose it to the user and offers no way to explicitly configure such connection. So in your case the answer is “no”.
