Hi,

Thanks for you answer....

This works when you make a server conexion.... but... When you create a client function works also the bind function? 

you see the function attachment to my first message. If I put a bind call in this function (client connect funcion) can i select the local bluetooth device? 

Regards,
Sir Graham.

  bind() to the address and channel of the local adapter you want to use before the call to connect()

    Hi,

    I need to use two bluetooth devices in the same computer with BlueZ.

    How  can I select (with socket) the device local that I like make a conexion?


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


    #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] = "01:23:45:67:89:AB";

        // 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 = (uint8_t) 1;
        str2ba( dest, &addr.rc_bdaddr );

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

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

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

        close(s);
        return 0;
    }

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

    Where can I select (in the example) what local module use?  ¿¿¿???

    Regards,
    Sir Graham.
