[android-porting] Wifi Issues WL1251

[DJ_Steve]

hello, its me again, ok im getting annoyed with a seemingly pointless
problem im having,
im trying to get ehe driver for the wl1251 wifi in my n900 working -
the module loads, calibration load etc but android wifi subsystem will
not scan for networks (keeps saying unable to scan) yet i can use
wpa_cli myself via adb to scan and retrieve the list of networks quite
hapily.

any ideas appreciated and i can post logcat output etc if needed

You've gone through the Wifi setup steps and created the necessary
sockets for wpa_supplicant to operate and all that?

wpa supplicant works fine if i launch it in a adb shell session and i
can then connect via wpa_cli and execute commands, just seems the
android ui isnt doing the same and it does throw errors related to
wpa_supplicant but i cant see why it does

can work this out.
