I do have CONFIG_CTRL_IFACE_DBUS_NEW enabled. I also tried
'supplicant-test' (which seems to only use the new interface) with mixed
results:
# supplicant-test
supplicant: Startup
^Csupplicant: Terminating
supplicant: Exit
i.e., it fails to start wpa_supplicant with the new DBus interface. However, if
I first
start wpa_supplicant by hand (wpa_supplicant -u -B), it works:
# supplicant-test
supplicant: Startup
supplicant: service_property() Debug level 2
supplicant: service_property() Debug timestamp 0
supplicant: service_property() Debug show keys 0
supplicant: debug_strvalmap() EAP method: MD5
supplicant: debug_strvalmap() EAP method: TLS
supplicant: debug_strvalmap() EAP method: MSCHAPV2
supplicant: debug_strvalmap() EAP method: PEAP
supplicant: debug_strvalmap() EAP method: TTLS
supplicant: debug_strvalmap() EAP method: GTC
supplicant: debug_strvalmap() EAP method: OTP
supplicant: debug_strvalmap() EAP method: LEAP
supplicant: service_property() key Capabilities type a
supplicant: system_ready() *
...
and so on, detecting wlan0 and a bunch of networks. ConnMan still won't find
wifi, however.
So it seems that the new interface is there, and works, but it can't be used to
start
wpa_supplicant (even though the dbus service file is there and has correct
content).
Could this be a permissions issue? I also think that out of the settings from
ConnMan
README I'm missing CONFIG_WPS and CONFIG_AP, are they absolutely needed?
I'll try recompiling with them later.
Regards,
Matti
