Re: [Bluez-users] bluetooth connection goes down

[Manjunath Prabhu <manjunath.mp@gmail.com>]

hi,
1> i am using the hcitool to get the rssi, lq and tpl
values........hcitool gives me these values only after a "cc" to my
neighbor BT device. Is there some other method to get these values????
Also, are there any other performance parameters specific to BT i can
measure, like delay??

2> I am using linux kernel 2.6.6 and currently available bluetooth
debian packages.

regards,
manjunath
