Hello,

[as we have some problems with CSR BC02 chips, and no one answer this on
 bluez-user, I'm reposting this on bluez-devel.]

I have some problems to send a file from a T68i phone via Obex to a
BlueZ Linux computer (2.4.21-mh2).

After some investigations, I have found that the problem is only when
the PC is configured as master,accept, and with a BlueCore02 version of
the CSR chip. (BlueCore01b is working OK).

I have done some tests with two differents bluetooth devices:
(Note: all the tests here are without sdp/obex server, as the problem is
before them).

- a USB dongle (Billionton):
    hciconfig hci0 revision
    hci0:   Type: USB 
            BD Address: 00:10:60:A2:48:AE ACL MTU: 192:8  SCO MTU: 64:8
            HCI 16.4
            Chip version: BlueCore02
            Max key size: 56 bit
            SCO mapping:  HCI

- a PCMCIA 3Com card:
    hci0:   Type: PCCARD
            BD Address: 00:04:76:E1:2E:A2 ACL MTU: 128:8  SCO MTU: 64:8
            HCI 11.2
            Chip version: BlueCore01b
            SCO mapping:  HCI

Here are all my tests:

So, my questions are:

- is this a correct behavior ?
- is this a problem with the BC02 core, or is this a wrong comportement
  of the BC01b (resulting of working better than the BC02 ;-) ?
- if this is a problem with the BC02 core, can we do something agins
  this ?

I don't understand why the communication is stopped when the role switch
is not done (due to the phone/pc initiating the communication refusing
it I think). Is this requiered by the BT specifications, or is this a
BC02 core bug ?

Thanks in advance for any help.
