Bluetooth programming - help please

[franko3]

Hello,

My first post on this forum
I am using Linux Mint few years now.
I decided to programming in bluetooth - write a simple chat program.
I did not found anything about issues which I encountered on this forum nor I don't know do I put this thread on right place so please move it in the right place if it's not.

I was following this example http://people.csail.mit.edu/albert/blue ... p-server.c and found out that when i try to bind i've got an error message invalid argument.
I am using Linux Mint 12 with latest updates.
Same example works on Mint 9 and probably on Mint 10.

I do not know where the problem is. Is it related whit bluez or with kernel.
Please anyone help.

On Linux Mint 12 I also have a problems with connect my samsung monte on bluetooth but i think that problem is related with nautilus and obex because of the error message it displays. Now I'm waiting on stable release LMDE to use it because I can browse my phone on this distro.

I think I found a bug in my program.
Unfortunately I did not read everything about the L2CAP from the above link.
It says that L2CAP use an odd ports numbers.
Here's what I learned from the mailing list linux-bluetooth:

That would be because the PSM value in the example is not valid. Newer
kernels (post 2.6.32) check for this properly:

/* PSM must be odd and lsb of upper byte must be 0 */
if ((psm & 0x0101) != 0x0001) {
err = -EINVAL;
goto done;
}

But problems with OBEX in Mint 12 still exists.
That's why I wait for new release of Mint or LMDE on which I can browse files in phone (tested).

Thank you for such great distro
