You need to add these libs to the .pro file as well:

-lbtapi -lpps -lbluetooth

So the full line should be:

LIBS += -lbbplatform -lbtapi -lpps -lbluetooth

In the 10.0.8 release you should be able to drop the last 2 and just have:

LIBS += -lbbplatform -lbtapi

Let me know how that works for you.

thank you for the answer. I added the libs to the. pro and the  function are accepted.

The problem tath I have now : 

When I Initializes the btspp library

int iN;
iN = bt_spp_init();

 this function return iN =13;

but i dont know if the initialization is successful

13 he corresponds with EOK or errno

my full  code is:

#include "app.hpp"

#include <bb/cascades/Application>
#include <bb/cascades/QmlDocument>
#include <bb/cascades/AbstractPane>
#include <btapi/btspp.h>

using namespace bb::cascades;


App::App()
{

    int iN;
	iN = bt_spp_init();

	qWarning() << "initialisation spp :";
	qWarning() << iN;



	char UUID[] = { (char) 0x00, (char) 0x85, (char) 0x5A, (char) 0xFE, (char) 0x28, (char) 0xED, (char) 0x11, (char) 0xda, (char) 0x94, (char) 0xd9, (char) 0x00, (char) 0xe0, (char) 0x81, (char) 0x61, (char) 0x16, (char) 0x5f };
	char addr[] = { (char) 0x41, (char) 0x07, (char) 0xCF, (char) 0x36, (char) 0x98, (char) 0xBA};
int openSpp;
openSpp = bt_spp_open(addr,UUID,true);
qWarning()<< "la reponse de la fonction bt_spp_open";
qWarning()<< openSpp;
	int deini;
	deini = bt_spp_deinit();
	qWarning() << "denitialisation spp :";
	qWarning() <<  deini;
 
    QmlDocument *qml = QmlDocument::create("main.qml");
    //-- setContextProperty expose C++ object in QML as an variable
    //-- uncomment next line to introduce 'this' object to QML name space as an 'app' variable
    //qml->setContextProperty("app", this);
    
    AbstractPane *root = qml->createRootNode<AbstractPane>();
    Application::setScene(root);
}

when i run thise code :

initialisation spp :
13
la reponse de la fonction bt_spp_open
-1
denitialisation spp :
16

I found the service from EOK
for more information:
http://www.qnx.com/developers/docs/6.4.1/neutrino/lib_ref/e/errno.html

so I know bt_spp_init () not work, because it not Returne EOK

Would somebody have an idea for a successful initialization ?

[actjak]

the return of          int bt_spp_init();    is 13

i find  that  means Permission denied     ( its define in errno.h)

in the bar-descriptor I selact all and it is the same probleme

I want to know how obtain the permission?

[kevhaz]

I get the same, but in a standard C console app...

    /* Initialise spp */

    int ret = bt_spp_init();

    if (EOK==ret) {

    fprintf(stderr,"Awesome: bt_spp_init=%d\n", ret);

    } else {

    fprintf(stderr,"Not so awesome: bt_spp_init=%d, errno=%d", ret, errno);

    }

just logs:

Not so awesome: bt_spp_init=13, errno=13

So are we missing some call to gain permission to use this API?

[kevhaz]

Also, I tried using bt_device_init t osee what that would do:

void bt_device_callback( const int event, const char *bt_addr, const char *event_data )

{

fprintf( stderr, "**** BT EVENT ****");

fprintf( stderr, "Event=%d", event);

return;

}

...

    int btinit = bt_device_init(bt_device_callback);

    if (0==btinit) {

    fprintf(stderr,"Awesome: bt_device_init=%d\n", btinit);

    } else {

    fprintf(stderr,"Not so awesome: bt_device_init=%d, errno=%d", btinit, errno);

    }

...

and that returned:

Process 16982225 (HelloWorld) terminated SIGSEGV code=2 fltno=11 ip=78024ea4(/base/usr/lib/libbtapi.so.1@bt_device_init+0x74) mapaddr=00004ea4. ref=001012c8

Hohum!

hello kevhaz

thank you for trying

look at this post :

[kevhaz]

Thanks, I guess that explains that one

[canurabus]

Is there any way to develop an app that uses a bluetooth serial profile without having an alpha? Any chance the bb10 simulator supports it? It's pretty frustrating sitting here with a Playbook and a bunch of ideas and code with no way to put any of it together.

[actjak]

I think the bluetooth is not available for the simulator
Because itry with the simulator and i have :

 bt_spp_init=2, errno=2

and you cane find in errno.h

#define ENOENT           2  /* No such file or directory                */

and I do not understand why btspp.h is not available for the playbook because btspp.h is not librerie CASCAD but qnx
