[Bluez-users] Broadcasting in Bluetooth

[Bluez-users] Broadcasting in Bluetooth

[Suresh Srinivasan]

Dear Maxim Krasnyansky,
                        Iam suresh srinivasan, doing my masters in computer
science at SMU. Iam currently looking at broadcasting in a bluetooth piconet.
>From my understanding from the bluetooth protocol stack is that broadcast
is not supported as of now. Iam trying do the following to broadcast a packet in the bluetooth
piconet:

1) Creating a connection(ACL) to all the slaves.
2) In function "HCI_ACL_SEND" the parameter "flag" in the function
hci_add_acl_hdr(skb,conn->handle,flags|ACL_START) is modified to flags|ACL_ACTIVE_BCAST".
Can i broadcast with the above changes? or do i ned some more changes?
Please, give me your valueable sugestions? please, guide me if iam in
the wrong direction.Eagerly waiting for your response,

Thanking you,
Warm regards,
suresh

Anyone know how to fix this:

gene@tr1a:~> bluepin
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
 
Traceback (most recent call last):
  File "/usr/bin/bluepin", line 39, in ?
    import gtk
  File "/usr/lib/python2.3/site-packages/gtk-2.0/gtk/__init__.py", line
43, in ?    from _gtk import *
RuntimeError: could not open display

Thanks,

Gene

Sorry about that. I inadvertantly tacked this to another thread. My
apologies.

You're trying to run the python-gtk bluez pin helper.  Are you actually
in X?

You could change your pin helper to just be:
#!/bin/sh
echo "PIN:1234"

or whatever yours is and the corresponding pin_helper line in hcid.conf

I guess ultimately you might want the python-gtk helper to work though.

It's probably some kind of authorization problem.  Are you able
to

xauth merge ~/.Xauthority

?
