[Bluez-users] Lost connection and caching

[Bluez-users] Lost connection and caching

[d B]

Hi all,

I'm using hcitool and bluez libraries to develop a simple application
on PDA and laptop.

I have noticed this behaviour:
I pair two dongles so I can retrieve information such as RSSI, Link quality=
....
If I extract the USB dongle from the laptop, the other one continues
providing  RSSI information, and hcitool con show me that the
connection is still alive.
Only after 10 secs  it recognize the disconnection. I guess there is
cache mechanism.
Where can I get more info about that?
Is there possible to force a refresh when I retrieve connection information=
?


best regards,
dB

the disconnect is easy. That is the disconnect timeout or supervision
timeout, but for the caching of RSSI I have no idea.
