[Bluez-users] Iscan turning off

[Bluez-users] Iscan turning off

Hi,

I'm using bluez utils 3.7 and I try to put the bluetooth card in my laptop
in piscan mode. The operation succeeds, but after a relatively short period
of time (about 10 minutes), the card goes back to just pscan. The reason I'd
like to have iscan is that my laptop does not appear to be discoverable
without it. Could anyone suggest what may be the issue? I am attaching my
hcid.conf file.

Thank you,
Timur

in device {} section, add:

   discovto 0;

This set the iscan timeout to 0 otherwise hcid will
put back the device in non-discoverable mode after
some time (for security reasons).

people, isn't there an FAQ for that (other than /faq.html) ?

Cheers.
