Is anyone working on auto-sniff support in bluez?

Hi Marcel,
I thought that in sniff mode we only reduce the duty cicle on a link
between two device, but you still could do transfer of data packets
within the negociated interval.
I've tested the sniff using:
hcitool cmd 0x02 0x0004 0x06(handle) - stop
hcitool cmd 0x02 0x0003 0x06(handle) 0x00 0x50 0x00 0x10 0x00 0x05
0x00 0x02 - start
So, what is still missing to be implemented? So far we have listed this:
- detecting idle link and link activity
- the timer
BR,
Eduardo.

what do you mean by this? In sniff mode you normally don't have any data
transfer at all. That's the only requirement. Thus you need a timer to
detect when a link goes idle.

Hi Marcel,
I've done some initial research on this area, and I've found some
proposals of algoritms for dynamic ajusting of sniff parameters based
on traffic history of the link. But before working with sniff
parameters, is there anything that neeeds to be done in the sniff mode
itself? Can you enumarate it?
BR,
Eduardo.

no and I never came around it. However this must be done inside the
kernel on HCI level. And you need to take sniff subrate from the Lisbon
specification into account now.
