[Bluez-users] ms intellimouse/wheel

[p er]

Hi,

I have a MS Bluetooth IntelliMouse with a wheel.
To get the wheel working I have to patch the kernel with the -mh patch.

Will there be one for 2.6.15 as well?
Will those patches ever be officially merged into the kernel?

Thanks
Per

I need to update the previous one, but I am a little bit short of time
right now. So it might take some days.

No. We need a generic HID subsystem.

Marcel

hmmm. I have this mouse and it works on 2.6.11-gentoo-r9. Does gentoo 
apply the mh patch? If so, I didn't know that, but lucky for me.

Do you mean that your patch prevents some other things from working ?

-mh in the kernel would be really great !

[Bluez-users] broadcast packets

[Aleksandar Kanchev]

Hello,

does bluez support broadcast packets ?
I've tried to send a raw broadcast packet to hci and I could see the 
remote bluetooth controller blinking as if it is receiving data but 
hcidump didn't show anything.
Before writing the packet I've connected the both devices with "hcitool 
cc <addr>" and I wrote the packet from the connecting side (the master).

Hi Aleksandar,

> Marcel, could you please answer me that ? :)

I already told you everything I know and I have no idea why you still
stick to the broadcast thing. Once you have established the piconet
between two devices, you can use it to transfer data. Doing everything
on HCI level is not a good idea. Use at least the L2CAP level for it,
but you might need to add some kernel code to make it work properly. The
broadcast stuff is not really used in any Bluetooth application so far.

Regards

Marcel

Re: [Bluez-users] broadcast packets

[Aleksandar Kanchev]

Hi Marcel,

I was away for a while :) But here's what I'm trying to do:
I'm using 2 laptops with 2 Belkin class 2 USB bluetooth dongles. Both 
laptops are running linux with bluez.
I want to broadcast packets from the one side to the other. To do that 
I'm connection both laptops with the hcitool and then from the master 
side I'm using the following code:
  int dd, i, ret = -1, hci_dev;
  u_short handle, flags;

  char buf[HCI_ACL_HDR_SIZE + L2CAP_SIZE];
  hci_acl_hdr *acl_hdr = (hci_acl_hdr *) buf;
  l2cap_hdr *l2hdr = (l2cap_hdr *) (buf + HCI_ACL_HDR_SIZE);
  uint16_t *psm = (uint16_t *) (((char *) l2hdr) + L2CAP_HDR_SIZE);
  char *l2cap_data = ((char *) psm) + sizeof(uint16_t);

  struct iovec iv[2];
  uint8_t type = HCI_ACLDATA_PKT;

  hci_dev = hci_get_route(NULL);
  dd = hci_open_dev(hci_dev);

  handle = 1;
  flags |= ACL_START;
  flags |= ACL_ACTIVE_BCAST;
  acl_hdr->handle = htobs(acl_handle_pack(handle, flags));
  acl_hdr->dlen = htobs(L2CAP_SIZE);

  l2hdr->len = htobs(sizeof(uint16_t) + L2CAP_DATA_SIZE);
  l2hdr->cid = htobs(0x0002);
  *psm = htobs(4097);

  for (i = 0; i < L2CAP_DATA_SIZE; i++)
    l2cap_data[i] = 'A';

  iv[0].iov_base = &type;
  iv[0].iov_len = 1;
  iv[1].iov_base = buf;
  iv[1].iov_len = sizeof(buf);
  writev(dd, iv, 2);

I can see the packet being transmitted on the local master side (with 
hcidump) but the other end doesn't seem to see it. At least hcidump is 
not dumping the packet.

Thanks

[bluez-users] Broadcast Packets

[Laurent DANIEL]

Hi,


I have 4 Broadcom USB bluetooth dongles and I want to send broadcast 
packet from the master's device to slave's device.
How could I realise this ? ( I use linux with Bluez 2.25)

At the moment I know that first I must create ACL links with each slave. 
Secondly, I must use the L2CAP level and not HCI level.

Moreover, I saw that I must change in a programm the BC flag. I must put 
it in ACL_ACTIVE_BCAST but how can I do?

Regards


Laurent
