Subject: [Bluez-devel] want duplicate inquiry results during a single device inquiry
Date: Fri, 13 Aug 2004 12:40:52 -0400 [thread overview]
Message-ID: <ef9938ec04081309406c2abae3@mail.gmail.com> (raw)
Hello,
While experimenting with a hp ipaq running a 2.4.19 kernel, I noticed
that during a since device inquiry, multiple EVT_INQUIRY_RESULT events
could be generated from the same remote device. The inquiry was done
using a raw hci socket. On x86 PCs running the same userland code but
with more recent versions of bluez and the linux kernel, the duplicate
events are no longer generated. Instead, during a single inquiry, a
response will be received from a remote device at most once.
I'm assuming that sometime in the recent past, kernel level caching
was implemented to prevent these duplicate inquiry results from
propagating up to user land. Is there a way to turn this off, so that
all inquiry results are passed through?
Thanks!
-albert
