How to connect two UT devices without internet?

To clarify my question: Both devices should receive stable (local network) IPs and both IPs should have similar rights. The hotspot schema does not fulfill this, I guess. In general, this approach should allow for 3 or more devices that can open sockets to others in the same local network.

@sven Why not posting your question on the Matrix UBports channel as well?

@C0n57an71n My question is not related to Matrix, it is about good old "ad-hoc wifi networks" to be found in the network managers of most Linux distributions.

@sven I was talking about UT channel on Matrix

@C0n57an71n Oh, I misread your message. I will have a browse in this channel, but maybe a forum is a better place for such topics. Let's see.

The hotspot feature can provide what you need. You don't need to have internet connection. Note though that hotspot can sometimes be tricky to make it work but it does work

I've actually used this setup before when I did app developments on my Nexus 5 via x-forwarding to my work laptop That was when RNDIS stopped working on xenial. I also use it for testing my apps to my other UT devices

With WiFi turned on, I tried to create a hotspot. I entered a name and a new password, then it took some seconds until the screen turned dark. A little bit scary ...

How can I wake up the OnePlus 3T? No connection via fastboot possible, VolumeUp + Power does not work.

I had to wait until the battery of the Oneplus 3T was empty and could reboot normally. The hotspot that caused the crash was available and worked like a charm for another UT device. So far, so good. But this strange thing is reproducible, experienced as follows.

With the hotspot turned off, I changed the hotspot name and pw. Again, the screen turned off and now I will have to wait until the battery is empty.

Can anybody reproduce this?
And if setting up a hotspot works for you without a crash, what device are you using?

@sven I don't have your phone but my mx4 did what describes @kugiigi last time i used hotspot (tricky to run, tricky to stop).

I won't test to change username and password because it's my daily ^^

I'll try on a spare N5 (have to update OTA first) when i have time.

I can add some details. The LED is on and white. The device is getting warm, so in a sense it is hot spot
