[Bluez-users] hcitool bug

[Pete Stevens]

Hi,

This confuses me, can anyone explain why I get this?

[root@pstevens bluetooth-pc-tag]# hcitool dev
Devices:
        hci0    00:0C:76:47:6A:94

[root@pstevens bluetooth-pc-tag]# hcitool -i 00:0C:76:47:6A:94 info
00:0E:6D:13:D8:74
Requesting information ...
Get connection info failed: No such file or directory

[root@pstevens bluetooth-pc-tag]# hcitool info 00:0E:6D:13:D8:74
Requesting information ...
        BD Address:  00:0E:6D:13:D8:74
        Device Name: Nokia 7600
        LMP Version: 1.1 (0x1) LMP Subversion: 0x24d
        Manufacturer: Nokia Mobile Phones (1)
        Features: 0xbf 0x28 0x21 0x00 0x00 0x00 0x00 0x00

                <timing accuracy> <role switch> <sniff mode> <SCO link>
                <HV3 packets> <CVSD>


If I specify the dongle by mac address it fails to get the info of the device.

For extra info

[root@pstevens bluetooth-pc-tag]# uname -a

i686 athlon i386 GNU/Linux

[root@pstevens bluetooth-pc-tag]# hcitool --help
hcitool - HCI Tool ver 2.4


Any got any ideas why this doesn't work?

Thanks,

Pete Stevens

Nice. With version 2.15 this fails with me. Do you have more than one
Bluetooth dongle in your computer?
[...]

I think it has to fail, because '-i <dev>' explicitly says "send it out
using this interface" and only affects remote devices. I don't think you
should be able to ask local devices for information in this way. But I may
be wrong.

        ciao,
          Stefan

At present I only have one, sometimes I have more than that.

I was under the impression I was using local device 00:0C:76:47:6A:94 to query
the remote device 00:0E:6D:13:D8:74, when I believe should succeed.

For what it's worth, it also fails if I address the device as hci0.

The explanation from me is not quite right, must be the long day :) 
I've read "00:0E:6D:13:D8:74" twice :( Sorry for the confusion.
The situation you reported works fine with me here, using version 2.15. It
doesn't matter here for me if I use hci0 or the bdaddress.
I think you should update your hcitool to a newer version.

        ciao,
          Stefan
