[Bug]: wpa_supplicant

[Dlazder]

Problem description

wpa_supplicant not working as expected.

I am running sudo wpa_supplicant -i wlan0 -c ./wpa.conf But get something like this

Successfully initialized wpa_supplicant
nl80211: kernel reports: Authentication algorithm number required
nl80211: kernel reports: Match already configured
nl80211: kernel reports: Match already configured
...........
...........

I have root

What steps will reproduce the bug?

Create wpa.conf using wpa_passphrase essidname password > wpa.conf

network={
        ssid="essidname"
        #psk="12345678"
        psk=532c4716b258a04164ea62f1518afd924c19c74676afd1a3983a4ada9dd70197
}

After this sudo wpa_supplicant -i wlan0 -c ./wpa.conf

What is the expected behavior?

I want to receive a message about successful or unsuccessful connection. I assume that all this depends in particular on the device, so this problem may not be for everyone.

Your error suggests that there is some range condition between your wpa_supplicant and other network configuration utility. This is not a bug or other issue kind of wpa_supplicant.

Disable Android WiFi management before using wpa_supplicant on your own.

@sylirre How can I turn it off? I didn't find any information about this. If you just turn off Wi-Fi then the wlan0 interface will not be available, I don't think that's it.

If you just turn off Wi-Fi then the wlan0 interface will not be available, I don't think that's it.

Indeed you have to turn wifi off. The interface does not disappear. You need to up it using ifconfig.

Termux wpa_supplicant and Android OS wifi management can't coexist as will conflict with each other.

If your device uses kernel modules, you need to load one with insmod first.

insmod is not provided by Termux. You may need to use one from /system/bin, /system/xbin or other system binary directory.

What module to load is device specific. sudo cat /proc/modules may give some hint: run when wifi enabled in Android and check difference with content when wifi is off.

[Dlazder]

No difference. In the first case I am connected to home Wi-Fi. In the second just turned off

In this case there is a difference, here I tried turn on Wi-Fi but do not connect to the hotspot

In the /system i have xbin directory, it's empty

I want to add an important detail, wpa_supplicant works, and I can process the output using the stream editor. A lot of different error messages bother me.
