Title: Pi Zero 2 and NetworkManager
Post by: kagouraki on June 24, 2022, 09:37:06 AM

Hello i have installed the NetworkManager reading older posts.
It works perfectly when in station mode. But when i try to make a Hotspot connection, i get this error :

Code: [Select]

tc@box:~$ sudo nmcli d wifi hotspot ifname wlan0 ssid OpenMFD
Error: Failed to setup a Wi-Fi hotspot: wpa_supplicant does not support Access Point mode
Is there a solution ?

EDIT: I have also 2 more questions.
1)Why is ModemManager running ? i never installed it.
2)how can i delete the 90-nm-thunderbolt.rules file ? pizero 2 has no thunderbolt and i dont need it. It throughs some error when booting and the networkManager extension is loaded.

Sure you did. It's a dependency of the  networkmanager.tcz  extension, see:

Rather than deleting it, installing a dummy rules file before  networkmanager  loads should be simpler.

Code: [Select]

tce-load -wil squashfs-tools.tcz

Code: [Select]

mkdir -p pkg/etc/udev/rules.d

Code: [Select]

echo '# nm_thunderbolt placeholder' > pkg/etc/udev/rules.d/90-nm-thunderbolt.rules

Code: [Select]

echo 'GOTO="nm_thunderbolt_end"' >> pkg/etc/udev/rules.d/90-nm-thunderbolt.rules

Code: [Select]

echo 'LABEL="nm_thunderbolt_end"' >> pkg/etc/udev/rules.d/90-nm-thunderbolt.rules

Code: [Select]

mksquashfs pkg no-nm-thunderbolt.tcz -noappend

Code: [Select]

rm -rf pkg
Copy  no-nm-thunderbolt.tcz  to your  tce/optional  directory.
Add  no-nm-thunderbolt.tcz  to the beginning of your  tce/onboot.lst  file.

Now when  networkmanager.tcz  loads, it will see the rules file exists and not copy its version over.

wpa_supplicant needs recompiling - I’ll have a look in the next couple of days.

Updated wpa_supplicant-dbus posted - ap mode not tested.

Thank you for the fast response.
The AP loads now and i can see it with my phone. Now the problem is that i cant connect to it. It seems that something is wrong with the password. I set the password with

Code: [Select]

sudo nmcli con modify Hotspot 802-11-wireless-security.psk 11223344and then when i check the connection with

Code: [Select]

nmcli -show-secrets c s Hotspotthere are two dashes in the psk field and not the password i insered.
when i see the config file in
/usr/local/etc/NetworkManager/system-connections/ with nano i can see the psk = 11223344 entry

so somehow the networkManager doesnt read the password from the config file  :(

Hi kagouraki
Maybe you need to run something like:

Code: [Select]

sudo nmcli connection reload

Is there something i can do or should i go with raspbian os ?
I have also other problems with piCore.
My waveshare touchscreen is hdmi with i2c touch but i cant make it work in piCore. I should probably open a new thread for the screen but i am just saying.
I would like to go with piCore because of the no sd corruption advantage. But maybe i should go for the raspbian os

Have you tried to configure the access point using wpa_supplicant directly rather than via networkmanager?

Please start a separate thread for the touchscreen.
