DO you run the SDP server? If not the KBtscoWorker::detectChannel(bdaddr_t * bdaddr) will fail and the default channel 1 is taken. If this isn’t suitable for you, just change the default channel in this method.

@sirkus: You need to compile the emu10k1 module into the kernel. Then you don't have the hwdep problem anymore.

But I've also a problem: the kbtsco doesn't use the right rfcomm channel. It selects "/x01" as channel. That's the output on the console. I'm using a Jabra BT250v headset. DO you have any hints?

Thanks a lot for your help (and of course your program), Whoopie

I this call fails.

err = sndctlopen(ctlhandle, cardid, 0))

This is something ALSA related. Iam not an ALSA Expert, but i would suggest to test this.

o Is the sndbtsco module loaded hunter david # lsmod | grep sndbtsco o Have a correct Alsa setup for it. o Does Alsa subsystem init the card ? hunter david # cat /proc/asound/cards 0 [ICH6 ]: ICH4 - Intel ICH6 Intel ICH6 with AD1986 at 0xdffffe00, irq 23 1 [Headset ]: Bluetooth SCO - BT Headset BT Headset 1 o Is There a Sound device for the BTsco card ? o Do the Sound Device have prober Permission ? o Does Alsamixer work on the BTsco card. david@hunter ~ $ alsamixer -c 1

Hello, good job, KBtsco found my (paired) headset, but…
i can’t connect to the headset, what’s wrong

KBtsco: KBtscoWorker::run cmd=1
KBtsco: KBtscoWorker::btscoOpen
KBtsco: KBtscoWorker::findDevice hwdep next device (hw:0): Operation not permitted
KBtsco: KBtscoWorker::findDevice control open (hw:1): Permission denied
Can’t find device. Bail: Permission denied
KBtsco: KBtscoWorker::run no cmd going to sleep

anyway this program is a very good idea for a simplier life.
