[Bluez-users] SOLVED: Dell Inspiron 8600 was: 'hciconfig -a' ok, but 'hcitools scan' shows no devices

["Andreas Schrell" <as@schrell.de>]

Marcel,

thanks a lot for your help.

SUMMARY:

hciconfig -a         looked right
hcitool scan         did not show any devices

RESOLUTION:

Bluetooth was diabled under Windows!
There was no way to start it from Linux as far as I know.

After booting Windows and activation Bluetooth (right click on icon in
task bar, then activate) it works under Linux. Nothing to do with <FN-F2>.
Now the blue Bluetooth LED is on even on Linux startup.

Thank You, Marcel, for your help!

Andreas
