I'm trying to debug a NetworkManager-powered wireless connection. It works when I feed wpa_supplicant with a custom wpa_supplicant.conf file written by me, but when I configure NetworkManager with the same parameters it does not work. I would like to know the exact parameters that NetworkManager is feeding to wpa_supplicant in order to compare with my custom configuration.

I can connect to wpa_supplicant using wpa_cli and I can retrieve each single parameter. But I would like to have a way to dump the whole configuration at once, or at least a way to have a list of all the parameters that I can fetch.

My system is running Debian sid with up-to-date packages.

NetworkManager sends it to wpa_supplicant over D-bus.

It is in the D-bus logs. For me it was in /var/log/syslog but I think it varies depending on the distro. It shows some lines like

Config: added 'eap' value 'PEAP'
Config: added 'phase2' value 'auth=MSCHAPV2'

I'm afraid you can't "dump" the set of parameters with wpa_cli. But have you taken a look at the files in the folder /etc/NetworkManager/system-connections? Could prove handy, I suppose.
