Hi,
I'm running Yocto Linux 1.4 with connman 1.12 and wpa_supplicant 2.0. I
know it's not the latest and greatest, but I hope you are still able to
help. I'm basically unable to get connman to recognize wpa_supplicant.
Starting 'connmand -d -n' I get
connmand[1478]: src/technology.c:technology_get() No matching drivers
found for wifi.
Furthermore, 'connmanctl technologies' lists only wired, and 'connmanctl
enable wifi' doesn't produce any output.
Connman is built with --enable-wifi (there is only tist.so under
/usr/lib/connman/plugins, but as far as I've understood, wifi is
built-in). At least 'strings /usr/sbin/connmand' produces a lot of
wifi-related output.
Wpa_supplicant is built with D-Bus support:
# ls /usr/share/dbus-1/system-services/
fi.epitest.hostap.WPASupplicant.service
fi.w1.wpa_supplicant1.service
org.bluez.service
# ls /etc/dbus-1/system.d/
bluetooth.conf connman.conf dbus-wpa_supplicant.conf
# dbus-send --system --dest=org.freedesktop.DBus --type=method_call
--print-reply /org/freedesktop/DBus
org.freedesktop.DBus.ListActivatableNames
method return sender=org.freedesktop.DBus -> dest=:1.24 reply_serial=2
array [
string "org.freedesktop.DBus"
string "fi.epitest.hostap.WPASupplicant"
string "fi.w1.wpa_supplicant1"
string "org.bluez"
]
test-supplicant seems to work:
# ./test-supplicant
state = INACTIVE

dbus.Byte(172), dbus.Byte(2), dbus.Byte(12), dbus.Byte(0)],
signature=dbus.Signature('y'), variant_level=1)
but test-new-supplicant gives an error:
# ./test-new-supplicant
ERROR:dbus.proxies:Introspect error on :1.2:/fi/w1/wpa_supplicant1:
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod:
wpa_supplicant was compiled without introspection support.
I'm able to connect wifi with wpa_supplicant alone.
