Hello,
I have 2 PC with Linux which once used to recognize each other by
"hcitool scan" and to create
a PAND-based connection.
Now I fail to see each other with "hcitool scan".
My question is :
I see now only the PSCAN flag when running "hciconfig" on both of then.
Is the ISCAN flag (inquiry) mandatory so that a device will be discoverable ?
following is full output on one of them:

Hi,
Thanks Frederic.
Ok, so I rebooted the machine and still
hciconfig shows:
UP RUNNING PSCAN
and also after 'hciconfig hci0 reset"
It stays "UP RUNNING PSCAN".
So what sould I do to make the ISCAN flag set ?
systemctl status bluetooth.service
shows that it is "active (running)"

Yes, ISCAN means that your adapter will respond to inquiry scan, so it
will be discoverable.
