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:
