hello,
I've been trying to make this application I'm working on run for over
a month now. it doesn't do anything extraordinary, just scans for
devices and if appropriate devices are found, sends a file via OBEX.
The thing is I'm getting all kinds of different problems all the time
that are very hard to decypher. So I ask (for BlueZ), is there any
tool that can help me with figuring out if there's anything wrong with
the stakc? If I did something wrong? Or how am I supposed to know?
for example: It happend to me twice that my app. failed with a SDP
request and since then, all the requests failed as well (for some
time). How do I know what I did wrong?
another example: I inquire for devices (my previous posts) but it
takes longer than I specify in the parameter. I can't afford to wait
for 3 minutes till the inquiry is over, cause all the devices I've
found could be out of reach by then. Again, how am I to know what went
wrong? Also, I've noted that sometimes, the hci_inquiry function
returns immediately (some result caching i suppose, and yes, I tell
the func. to flush the cash).
last example: "I got a Software caused connection abort" error from
OBEX (which runs on top of the RFCOMM protocol afaik). What, how, no
documentation, google doesn't know either. What went wrong?
I study the sources, I study the other sources, I search all the
mailing lists I've found for the answer, but most of the time to no
avail.
1) how can I tell what went wrong, is there a diagnostic function in the st=
ack?
2) I don't mean to be impolite, but you should consider putting
together some documentation. I know you probably don't get paid for
this, you do it in your free time (I'm talking about the authors), but
that would really be a good idea. Just 10 lines of comments for each
function, is that too much to ask? Not that I couldn't imaigine what
function hci_inquiry does, but figuring out all the pitfalls (as many
already have I believe) is very tedious. I can offer my help (that's
not much considering my knowledge) with documentation if you want.
thanks, Jan

Hi Jan,
>From my experience, some errors that you have shown seem to be normal
with the Bluetooth stack. Usually, trying later works. Remember that
Bluetooth is not TCP/IP. As a debugging tool, you can try recompiling
bluez in debug mode, so that it shows all kind of messages and you can
use gdb with it. I would also encourage you to use hcidump and patiently
analyze the logs it generates.
Cheers,
Pedro
