@javierbarellano4v Does the Raspberry PI have wpa_supplicant installed?

javierbarellano4v commented 1 year ago

I had done the configuration changes for wpa_supplicant as described in instructions in link but I had missed one file change which I did make and restarted the pi:

https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/BUILDING.md

Unfortunately, still get the same error.

Did I need to install something related prior to the configuration changes?

Thanks.

javierbarellano4v commented 1 year ago

I replaced original ExecStart line in /etc/systemd/system/dbus-fi.w1.wpa_supplicant1.service with:

ExecStart=/sbin/wpa_supplicant -u -s -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

Next, in /etc/wpa_supplicant/wpa_supplicant.conf, I replaced with:

ctrl_interface=DIR=/run/wpa_supplicant update_config=1

javierbarellano4v commented 1 year ago

with regards to /etc/wpa_supplicant/wpa_supplicant.conf file, that's all i have in the file, the two lines in previous post.
