Hi, im a beggineer in bluez and also in programming stuff, i have read
a coupble of things about bluez and programming,  what i want to do is
a progran that send files to the phone is near by,,im trying to get
work these code, its compile, and conect to the phone , but in the
phone ask for a number security, ahta later i have to type in the
computer...... how can i send a file whitout asking a number? just
asking in the phone about aceptting the file
#include <stdio.h>
#include <unistd.h>
#include <sys/socket.h>
#include <bluetooth/bluetooth.h>
#include <bluetooth/rfcomm.h>

int main(int argc, char **argv)
{
    struct sockaddr_rc addr = { 0 };
    int s, status;
    char dest[18] = "00:23:F1:CC:BF:10";

    // allocate a socket
    s = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);

    // set the connection parameters (who to connect to)
    addr.rc_family = AF_BLUETOOTH;
    addr.rc_channel = 1;
    str2ba( dest, &addr.rc_bdaddr );

    // connect to server
    status = connect(s, (struct sockaddr *)&addr, sizeof(addr));

    // send a message
    if( 0 == status ) {
        status = send(s, "hello!", 6, 0);
    }

    if( status < 0 ) perror("uh oh");

    close(s);
    return 0;
}

Well, in this case the phone requires authentication to connect to the
service on RFCOMM channel #1 so you are out of luck unless you can provide
the same PIN at both ends (or other pairing)

You need to investiage "OBEX Object Push". Sometimes you can send a text
file without authentication, but the person who owns the phone will
usually be required to authorise the connection (ie a message will appear,
asking if they wish to receive the file and they will need to approve)

It is a long way to do it yourself, look for "obexd" at www.bluez.org

A couple of weeks ago, I posted this question, and haven't heard anything back.  Is there someone out there that can help me?


Hi.... I have problem when removing a device from use.  I have two identical devices connected to my host.  For each of them I disconnect the device, then remove it.  Sometimes it works just fine, and sometimes it seems something doesn't finish, and a timeout error is returned.  When it doesn't finish, I can't do anything any more.  A scan doesn't do anything, and if I try to turn off the scan I get an InProgress error.  Here is a log produced by running 

bluetoothd -experimanal -debug -n

If you could help me figure out why it works in once instance and not the second, I would very much appreciate it.
