It works. It's not pretty, but I have an open access point running.
But first, I decided to try with a Raspberry Pi 4 I had. Same results. Then I tested hostapd. Same results. It meant something's wrong on the Pi Zero at a low level, the hardware, or the driver, or, well, something else. Ok let's find a workaround. In hostapd.conf, there is a directive named auth_algs, and I set it to 0 so that no auth is necessary. Should work, right?I was flabbergasted. I couldn't create a working open access point. It was forbidden. I was sad. Then I got angry.
Then, wait, this is open source. I can have a look and see what can be done. As a normal user:Going in the wpa-2.10/src directory it created, I launched "make", but nothing seemed to be generated. That's because .o files live in another directory. Also, after much fumbling, it appears that you need to define CONFIG_WEP so that the related #ifdef directives get compiled (the comments indicate it could be removed in the future). In the wpa-2.10/hostapd subdirectory. "make" wants a .config:Uncommenting CONFIG_WEP=1, typing "make", getting errors about missing dev libraries:I have an executable.And I have a script to test it on the Pi Zero, testapd.sh. The "sleep 1" lines seem necessary for the dust to settle, because sometimes the Pi Zero can't find the hotspot if there's no delay between these instructions. The "sleep 60" at the end allows me to ping the Zero from the Pi 5, thus proving the machines are communicating properly. You run it as root in the background, so that when the ssh connection stops because it switches to another AP, it keeps logging everything, stdout and stderr, in testhostapd.log.Aaaaand…See the SECURITY column. That's why I can connect without a password. It suits me for my application but, kids, don't try this at home.
Conclusion: all hail Open Source Software.
