Hello everybody,
This is an "interesting" one, as I've been banging my head against the desk for days now trying to connect two RPis on Raspbian Bookworm via wifi. I want to control a slideshow using a remote keyboard connected to a Raspberry Pi Zero, communicating with a Raspberry Pi 5 configured as an access point, where the slideshows also occurs. No Internet access needed, it's a closed system. Since the machines could be up to 20 meters apart, I can't reliably use Bluetooth, so it has to be wifi.
The AP is launched this way, which gives the choice of 2.4 GHz or 5 GHz according to my laptop wifi parnel:
The Pi Zero connects to my wifi router, using either the desktop interface or nmcli. No problem. I have set up an access point on my Pi 5, and I can connect to it with almost anything, like my phone or my Ubuntu 20.04 laptop. No problem.
But the Pi Zero doesn't want to connect.
I've been scouring the Internet, I've tried various solutions, various utilities, but none worked. When a connection was initiated, it always failed with the same message. The --ask-password option – ditto. I've tried messing with the configuration files themselves, in /etc/NetworkManager and other, more mysterious places. If I can use a password file (a few "solutions" talk about it), I need to know its format and the directives to use, and this is hard to come by. I have strace'd the nmcli process, and I see something coming from dbus, but I don't know the origin. I have reinstalled the Raspbian image. I have tried setting up an open AP without any security since I don't care: the RPi5 is not connected, and there's nothing valuable on the machine itself apart from pictures – but it seems impossible with nmcli which apparently wants security no matter what.
Any idea?
