[Bluez-devel] Error connecting after inquiry

Hello,
I am developing an application that connects to the Nintendo Wii remote,
which is a bluetooth device, using BlueZ.  The API allows a bdaddr to be
supplied, or not.  If it is not supplied, the API invokes a search function
that does an hci_inquiry to get all available devices, hci_open_dev to get a
device connection, then traverses the array, calling hci_remote_name and
checking the class for each item returned from hci_inquiry until a Wiimote
is found, closes the hci device, and returns the bdaddr of the Wiimote.  The
calling function then opens a couple of L2CAP sockets and proceeds to
communicate with the device.

Here's my problem: many users receive errors on the L2CAP socket open only
when a bdaddr is not supplied, but it works fine when the bdaddr is provided
(thus skipping the search procedure described above).  I've verified that
the bdaddr returned by the search function is, in fact, identical to that
supplied, so the parameters to the socket open call are identical.  It
happens every time on some machines, and never on others - to my knowledge,
there are no intermittently failing machines.  Any ideas?

The calling function is cwiid_connect, listed in
http://abstrakraft.org/cwiid/browser/trunk/libcwiid/connect.c
The search function is cwiid_find_wiimote, which calls
cwiid_get_bdinfo_array, both listed in
http://abstrakraft.org/cwiid/browser/trunk/libcwiid/bluetooth.c

Thanks for any help you can provide,
