[Bluez-users] Pairing problem with Plantronics headset

[Bluez-users] Pairing problem with Plantronics headset

[John Gruenenfelder]

I am attempting to use btsco with my Plantronics M2500 headset.  I am using
the most recent Debian bluez-utils packages (3.1-3).

The headset's passkey/pin is "0000" which I have set in both
/etc/bluetooth/hcid.conf as:
  passkey "0000";

and in /etc/bluetooth/passkeys/default as just "0000".

When I turn on the headset, put it in pairing mode, and then attempt to run
btsco, I get the following from btsco:

-----
./btsco 00:03:89:6E:C9:11
Error: Failed to connect to SDP server: Permission denied
Assuming channel 2

Can't connect RFCOMM channel: Permission denied
-----

In the system logs the only new entries generated are:

Jul 31 19:32:52 Redtail hcid[5743]: pin_code_request (sba=00:16:41:89:98:00, dba=00:03:89:6E:C9:11)
Jul 31 19:32:52 Redtail hcid[5743]: Calling PasskeyAgent.Request: name=:1.5, path=/org/bluez/passkey_agent_5755
Jul 31 19:32:56 Redtail hcid[5743]: pin_code_request (sba=00:16:41:89:98:00, dba=00:03:89:6E:C9:11)
Jul 31 19:32:56 Redtail hcid[5743]: Calling PasskeyAgent.Request: name=:1.5, path=/org/bluez/passkey_agent_5755

To me, these seem to indicate that the PIN is being requested, but perhaps not
being returned properly?  I also tried creating a passkey explicitly for this
device as:
  /etc/bluetooth/passkeys/00:03:89:6E:C9:11

But the log messages were the same for this instance.  What am I doing wrong?
Thanks in advance.

run "hcidump -X -V" and try again to see what is going on.

Thanks for the quick reply.  I ran the above command and saw in the output
that the requested pin was being delivered as 0000.  But I also noticed that
the length was 5 bytes.

Looking closer, I see that the pin is actually 0000 plus 0x0A.  I had set the
pin by:
  echo "0000" > default

But that tacked on a linefeed.  Using "echo -n" instead solved the problem and
now the headset pairs and I get audio via btsco.  Thanks.

[Bluez-users] Problem developing bluetooth program

[Mate Soos]

Hi!

I have been having problems developing a bluetooth program of mine. The
problem, simply put: I open an RFCOMM socket with socket(), bind(),
connect(), and whatever I do, the connect() will fail with Invalid
Argument. I have now made this *extremely simple* program, and I am
having the same damn problem:

#include <bluetooth/bluetooth.h>
#include <bluetooth/rfcomm.h>
#include <iostream>
#include <errno.h>
#include <string.h>
#include <sys/socket.h>

int main() {
    int s;
    int channel=3D40;
    char addr[40],addr2[40];
    strcpy(addr,"00:11:67:39:05:0F");
    strcpy(addr2,"00:11:67:39:36:BB");


    std::cerr << "RfcommSocket::connectToHost from " << addr2 << " to
addr: "<< addr << "," << channel << std::endl;
    sockaddr_rc rem_addr, loc_addr;

    if( (s =3D ::socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM)) < 0 ) {
        std::cerr << "Can't create socket" << strerror(errno) << errno
<< std::endl;
        return -1;
    }

    memset(&loc_addr, 0, sizeof(loc_addr));
    loc_addr.rc_family =3D AF_BLUETOOTH;
    str2ba(addr2,&loc_addr.rc_bdaddr);
    if (bind(s, (struct sockaddr *) &loc_addr, sizeof(loc_addr)) < 0 ) {
        std::cerr  << "Can't bind socket"<<  strerror(errno) << errno <<
std::endl;
        return -1;
    }

    memset(&rem_addr, 0, sizeof(rem_addr));
    rem_addr.rc_family =3D AF_BLUETOOTH;
    str2ba(addr,&rem_addr.rc_bdaddr);
    rem_addr.rc_channel =3D channel;
    if(::connect(s, (struct sockaddr *)&rem_addr, sizeof(rem_addr)) < 0 ){
            std::cerr << "Can't connect." << strerror(errno) << errno <<
std::endl;
            close(s);
            return -1;
    }
    std::cerr << "Connected." << std::endl;
return 0;
}

Output of program:

00:11:67:39:05:0F,40
Can't connect.Invalid argument22

I have *really* read through all the revelant details, I have been
reading the libbluetooth sourcecode nonstop(!), I have copy-pasted
several examples, no luck. It always gives me this stupid error, and I
am totally fed up with it. I have been getting it for the past 1.5
weeks, and I work 4 hours per day on this. Any ideas?

I really appreciate all help,

Re: [Bluez-users] Problem developing bluetooth program

[manojt ambe]

Are you sure channel 40 exists on your device. Try
sdptool browse <bdaddr> or sdptool records command to
find out.
Also i think try following to fill in sockaddr_rc. It
may remove some unwanted characters.

  char *bdaddr_str;
  bdaddr_t bdaddr;
  struct sockaddr_rc addr;
  int channel=3D40;

  bdaddr_str =3D "00:11:67:39:05:0F";
  str2ba(bdaddr_str, &bdaddr);

  memset(&addr, 0, sizeof(addr));
  addr.rc_family =3D AF_BLUETOOTH;
  bacpy(&addr.rc_bdaddr, bdaddr);
  addr.rc_channel =3D channel;

thanks,
Manoj
