Hi all,
I'm trying to get wifi working with connman. I'm using a TL-WN722N
dongle. I've enabled the kernel drivers and installed the firmware,
also I can connect to wifi using wpa_supplicant + wpa_cli, but when I
try to enable wifi technology on connman I get this error:
root@enlace-imx6:~# connmanctl enable wifi
Error wifi: Method "SetProperty" with signature "sv" on interface
"net.connman.Technology" doesn't exist
The weird part is that wpa_supplicant can connect. So here are my questions:
1) Does connman need a kind of driver or something like that for each
wifi card or it uses some generic kernel interface for it?
2) Should wpa_supplicant be running when `enable wifi' is tried? Is
there a "right way" to start wpa_supplicant? I'm using this line
`wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf', is that right?
3) I know that connmanctl error has something about dbus. Is there any
command to check dbus interfaces? (Dbus newbie here)
4) I've build the drivers for dongle as built in kernel (no module).
Can this be fooling connman?
I'm running a Poky distribution v1.7 (build from Yocto Dizzy). The
wifi plugin seems to be builtin (How can I ensure that?). The
processor is an i.MX6 (quad core). Kernel 3.14.28. Drivers: ath9k_htc
build as "built-in".
Some more information on my system below
Best regards,
