[Bluez-devel] bluetooth-alsa and HAMA BTH-155

[Christian Mager <christian.mager@gmail.com>]

Hello,

I followed the instructions of bluetooth-alsa.sf.net to get my bt
headset work but pairing doesn't work so far. snd_bt_sco is loaded and
when I run btsco I get the following output:

$ btsco -v 00:13:8A:04:A3:43
btsco v0.42
Device is 1:0
Error: Failed to connect to SDP server: Permission denied
Assuming channel 2

Voice setting: 0x0060
Can't connect RFCOMM channel: Permission denied

Yes, I have restarted /etc/init.d/bluez-utils. I also started btsco as
root but same result. Pairing the headset with my cell phone works, but
it asks for a pin, btsco desn't. Could this cause the problem? In
/etc/blueooth/hci.conf there is 'pin_helper /usr/bin/bluez-pin;' and 'lm
accept;'.

On your project site you wrote, that the following information could be
useful for you:

If you need more info just let me know.

Could it be possible that my headset itself doesn't work with
bluetooth-alsa? I would be very happy if someone could help me. Any
ideas how to solve this?
