Hi all!
I am currently playing around in setting up IP ad-hoc networks using
bluez. olsr-over-bluetooth works, and `pand -Q` is a nice thing :)
The bad stuff is that inquiry & connecting can take some time, but its
hard to really do something against that. (I have a few hacks in mind,
but they wont scale)
What would be really nice is some link quality metric. On my mobile
device `hcitool lq` always returns 255 (Even if the link goes bad and
the other side sees it). But I have one metric in mind: the interface
gets destroyed if a certain number of packets are not acknowledged by
the receiver. Is there some way (other than writing a script that
listens to hcidump) to measure this? `ifconfig bnep0` shows errors:0
and dropped:0 until it is detroyed. I am not a kernel hacker, i looked
around a bit in the bluez module, the library and pand, but couldnt
really find anything...
Do you have any hints? Is there any "unacknoledged packets" metric
accessible from userland? Where is the code that destroys the bnep
interface after x packets?
Thanks in advance,
Kosta
PS: Are you interesed in a "zeroconf ip" patch for pand?
