Hi,

I need to use two bluetooth de= vices in the=20 same computer with BlueZ.

How can I select (with s= ocket) the=20 device local that I like make a conexion?

If I make a simple conexion...= Can I select=20 what of my local modules (HCI0 or HCI1) makes this=20 conexion?

#include <stdio.h>
#inc= lude=20 <unistd.h>
#include <sys/socket.h>
#include=20 <bluetooth/bluetooth.h>
#include <bluetooth/rfcomm.h>
int=20 main(int argc, char **argv)
{
    struct sockaddr_rc a= ddr =3D=20 { 0 };
    int s, status;
    char dest= [18]=20 =3D "01:23:45:67:89:AB";

    // allocate a= =20 socket
    s =3D socket(AF_BLUETOOTH, SOCK_STREAM,=20 BTPROTO_RFCOMM);

    // set the connection parameters= (who=20 to connect to)
    addr.rc_family =3D=20 AF_BLUETOOTH;
    addr.rc_channel =3D (uint8_t)=20 1;
    str2ba( dest, &addr.rc_bdaddr=20 );

    // connect to server
    sta= tus =3D=20 connect(s, (struct sockaddr *)&addr,=20 sizeof(addr));

    // send a message
  &= nbsp;=20 if( status =3D=3D 0 ) {
        statu= s =3D=20 write(s, "hello!", 6);
    }

  = ; if(=20 status < 0 ) perror("uh oh");

   =20 close(s);
    return 0;
}

Can I select what of my local = modules (HCI0=20 or HCI1) makes this conexion?

Where can I select (in t= he example)=20 what local module use? =BF=BF=BF???

&= nbsp;

Regards,=

Sir=20 Graham.
