[Bluez-devel] Building btsco for Fedora 3

[Bluez-devel] Building btsco for Fedora 3

Hi. Hopefully this is the right list for this question.

I'm attempting to build btsco and the associated kernel driver for 
Fedora 3, kernel 2.6.11-1.14_FC3

With btsco, I get ...

> make[2]: Entering directory `/tmp/btsco'
> gcc -DHAVE_CONFIG_H -I. -I. -I.    -I/usr/include -Wall -O2 -c a2recv.c
> a2recv.c: In function `make_master':
> a2recv.c:281: error: incompatible type for argument 2 of `hci_switch_role'

So, first question, can I get away with commenting out the relevant call?

Second question concerns the kernel driver, and to be frank my inability 
to keep up with the fedora build process. I get:

> make: *** /lib/modules/2.6.11-1.14_FC3/source: No such file or 
> directory.  Stop.

Turns out no modules source directory was installed with this kernel 
rpm, though it does exist for older kernels. Any tips? I'm guessing this 
is an issue with the kernel rpm?

Any help appreciated.

Mark

Yes. This is from a2recv which you probably won't need anyways (it's for
receiving A2DP audio data) and that specific function is only a
workaround for the behaviour of the iPHONO audio dongle.

Hmm, can't help you with that (I'm mostly always using vanilla kernels
from kernel.org) but you will probably need the kernel sources to
compile.

yes, great.

go ahead and comment it out. i had no idea this api had changed though.

source is a softlink to the source dir on my machine. it may be good 
enough to install the kernel-header package for your kern version. look 
for a kernel-source package too.

Thanks Brad. Turns out the link was the thing I missed. Made link, made 
config in kernel source dir and the driver built. Now (and firstly, I'm 
probably continuing to be dense, and probably secondly, in the wrong 
list at this stage) after depmod the mod loads OK but when I try:

btsco <device address> 1

.. when in pairing mode on the device (a jabra 250) I get

Can't connect RFCOMM channel: Resource temporarily unavailable

I've set the default pin via bluez-pin, was previously seeing auth 
requests in log.

Mark,

> btsco <device address> 1

try it without specifying the '1' (the channel should be autodetected)

btw, does it say anywhere in our docs that you need to specify the channel?

You're right, it doesn't. I was following various examples from Google.

Here's my attempt to connect, with tail -f /var/log/messages in the 
background:

/etc/bluetooth/pin contains:

0000

I'm not confident the pin number is actually moving across ... bluepin 
never asks for input during the run
