How can I get the Bluetooth Address??

[liuyaxin]

I want to do an application using openobex.
I want to use it for sending and receiving files. And I want to know the sender's or the receiver's bluetooth address. I have checked the openobex apidocs very detailed. But I didn't find some functions that I can get it. So who can help me?? Or give me some hint??:)

It's been discussed on the list before. In summary:
use  OBEX_GetFD() to get the socket, then getpeername() to retrieve the sockaddr.
HTH. Let me know if this solves the problem.

It works.
But I have a new problem.
When a new connection is accepted, I use OBEX_GetFD and getpeername to retrieve the sockaddr. The sockaddr isn't exactly the real address It has some differences.
For example, the real address is '00:1A:16:C0:51:B4'. But the address in my program is '00:0A:00:1A:16:C0'. I don't know why? Can you help me??

Sounds like you are programming a server. If you use this on a listening socket you'll get the address of your local hci. You need to call it on the established connection.

Yes, I am programming a server.
But I didn't use this on a listening socket. It's on the accepted socket.
And I use another method to solve this problem.

int get_bdaddr(obex_t *handle, char *str) {
        int fd;
        unsigned char name[100];
        int i;
        fd = OBEX_GetFD(handle);
        if( fd < 0 ){
                return 0;
        }
        if( getpeername(fd, (struct sockaddr *)name, &len) ){
                return 0;
        }
        sprintf(str,"%02X:%02X:%02X:%02X:%02X:%02X",name[7],name[6],name[5],name[4],name[3],name[2]);
        //ba2str(&client_saddr.rc_bdaddr,str);
}

The bluetooth address is on the range 2-7 of the array name.
