I've reported this as bug #5018675 at bugreport.apple.com
Begin forwarded message:
we're using the COD of our embedded bluetooth network nodes
(www.btnode.ethz.ch)
as a way to identify nodes on which a particular application is
running.
This leads to a problem on Mac OS X as it looks like (at least) the
COD is cached.
Its not clear to me, why this is done, but playing with the
Bluetooth Inquiry Example
shows that the COD of my device does not change although I change
it in parallel.
Also, the COD of a discovered device is included in the HCI Inquiry
Results, so this value
could directly be used, if a device is reported.
I've read in the BT docs, that the amount of Inquiries are
throttled. What are the
parameters for that ? Once every 10 seconds, every minute, every hour?
I tried to call clearFoundDevices on the IOBluetoothDeviceInquiry
object, but no change.
Ok. Is there a way to "force" the bluetooth framework to use the
real discovered
CODs or to discard its cache?
