I seem to be having a problem with ISCAN. Sometimes it is initiated, sometimes it is not. I have to run several hciconfig down/up commands until I can see ISCAN in hciconfig -a output. Obviously my hcid.conf is set up properly (unedited debian sid version) or else I would never see ISCAN.

Does nyone have any thoughts, I'm happy to provide anything else that may help.

NOW YOU SEE IT.. NOW YOU DON'T see below...

Hi,

Quoted 5 lines

I seem to be having a problem with ISCAN. Sometimes it is initiated, sometimes it is not. I have to run several hciconfig down/up commands until I can see ISCAN in hciconfig -a output. Obviously my hcid.conf is set up properly (unedited debian sid version) or else I would never see ISCAN.

install bluez-gnome-0.6 and use the Bluetooth preferences application to disable the automatic switching back into non-discoverable mode.

Regards

Marcel
