[Bluez-devel] linux 2.4.20 & alsa 0.9.6

[Bluez-devel] linux 2.4.20 & alsa 0.9.6

[pdjj14]

Hi~
 Thank you for your kindness. ^^
 I want to listen the music which be played at PC as BT headset.
 My environment is Redhat 9.0 + kernel 2.4.20-8 + bluez-utils-2.10 + bluez-
libs-2.10 + bluez-hcidump-1.10 + alsa-dirver-0.9.6 + alsa-lib-0.9.6 +
bluezsco-0.1.

 I want to play the music with alsa.
 When I installed the alsa, I referenced web page
(http://www.dcs.gla.ac.uk/~jp/snd-bluez-sco/README)
 But, when I type 'bluezsco', I see the error message.
	[root@wooki bluezsco-0.1]# ./bluezsco
	Error: control open (hw:0): No such file or directory
	Error: Can't find device. Bail
 Device hci0 is enable state.
 I always work as root.
 Necessary modules(rfcomm, sco, l2cap...) already loaded.
 I want to know if I miss somethings.
 I want to know method to succeed.

 Another question is about hciconfig.
 When I type hciconfig -a, I see the message.
	[root@wooki alsa-lib-0.9.6]# hciconfig -a
	hci0:   Type: USB
        BD Address: 00:0B:24:01:23:B3 ACL MTU: 192:8  SCO MTU: 64:8

        HCI Ver: 1.1 (0x1) HCI Rev: 0x33c LMP Ver: 1.1 (0x1) LMP Subver:
0x33c
        Manufacturer: Cambridge Silicon Radio (10)  When I type hciconfig
hci0 revision, I see the message.
	[root@wooki sco]# hciconfig hci0 revision
	hci0:   Type: USB
        BD Address: 00:0B:24:01:23:B3 ACL MTU: 192:8  SCO MTU: 64:8
        HCI 16.14
        Max key size: 16 bit
 The other's result different from mine.
 I want to see more informations as 'Chip version', 'SCO mapping'.
 My dongle is based on 'Cambridge Silicon Radio'.
 What do I do more to see more informations?

 I can't change my environment as kernel version up.
 Because, at final, I will load the program to the target board.
 The target board's environment already be promised by co-workers.
 
 Thank you...I will wait for your response. ^^

bluezsco has been unsupported for a long time. use btsco. Kernel 2.4.x
is really tough to get workig with bluetooth audio. If you could use a
current 2.6.x you will have better luck.

hciconfig is also old. i think that's why it doesn't report the sco mapping.

 Thank you Brad...
 I have a question...
 To communication between PC and Headset using the bluez, I don't work in
my environment?
 I can change bluez-utils' version, but, I can't change kernel version.
 Are there other methods?

I understand there are a lot of embedded platforms that are still on
kernel 2.4. You may be able to get audio working with 2.4.x using old
versions of everything, but you aren't likely to get help on the mailing
lists for doing that. Good luck.
