patch for that is floating around the kernel mailing list. It is
COMPAT_CONFIG issue and fully my fault.

[Bluez-devel] What can I do in parallel

[Matthias Becker]

Hi,

I write an aplication that is intended to push a file to all surrounding
mobilephones. So it performs an inquiry scan and than starts threads for
all recived addresses to push the file.

But I need to know what is allowed to do in parallel. 

(I know that I can't read multiple names via hci_read_remote_name. But I
don't need those names anyway.)

To push the file I need to get the OBEX push channel. Can I do multiple
SDP requests over one bluetooth adapter at the same time?

hcidump shows me that SDP seems to perform a name reuest. Why is this?

(an excerpt from hcidump while a call to "sdptool browse
00:19:63:9D:09:16":
...
< HCI Command: Remote Name Request (0x01|0x0019) plen 10
    bdaddr 00:19:63:9D:09:16 mode 2 clkoffset 0x0000
> HCI Event: Command Status (0x0f) plen 4
    Remote Name Request (0x01|0x0019) status 0x00 ncmd 1
> HCI Event: Max Slots Change (0x1b) plen 3
    handle 12 slots 5
> ACL data: handle 12 flags 0x02 dlen 16
    L2CAP(s): Connect rsp: dcid 0x0040 scid 0x0040 result 1 status 0
      Connection pending - No futher information available
> HCI Event: Remote Name Req Complete (0x07) plen 255
    status 0x00 bdaddr 00:19:63:9D:09:16 name 'K800i'
...
)

Than I need to do the OBEX stuff (using OpenOBEX
BtOBEX_TransportConnect, ...).

If I can do things in parallel how many can be performed in parallel per
bluetooth adapter? I read something about bluetooth allows 7 active
connections and 255 passive connections, but I'm not sure what that
meens.



Thanks in advance

-- Matthias
