[maemo-developers] [maemo-developers] Connectivity API: ( osso_iap_connect() ), cannot see generated events

[From: Jarkko Palviainen]

Hi,
I'm trying to create WLAN connection with osso_iap_connect() call from my  
applications (which is a gtkmm app). I can make a proper connection as  
N770 pops the "Connected to foobar" message, but connected callback does  
not ever get any signals, like OSSO_IAP_CONNECTED, OSSO_IAP_DISCONNECTED  
or OSSO_IAP_STATISTICS.

The code are pretty much same as in the maemo connectivity tutorial  
(http://www.maemo.org/platform/docs/howtos/howto_connectivity_guide.html#ConnectivityAPIFunctionality),  
I will also put them here:

Inside the class constructor connect the signal handler:


ClientSocket::ClientSocket(Clientmain& client_) :seq(0), client(client_)
{
	...
	
	// Register a callback function for IAP related events
	if (osso_iap_cb(iap_callback) != OSSO_OK) {
		cout << "osso_iap_cb failed" << endl;
		exit(1);
	}

	...																						
}

method for creating connection to IAP:

bool ClientSocket::open_wlan_connection(void)
{
	int n;
	n = osso_iap_connect(OSSO_IAP_ASK, OSSO_IAP_REQUESTED_CONNECT, NULL);
	if (n < 0)
		return false;
	else {
		// osso_iap_get_statistics(iap_name, (void*) 0xF00BA4);
		cout << "wlan opened" << endl;
		return true;	
	}	
}

and callback:

static void iap_callback(struct iap_event_t *ev, void *arg)
{
	cout << "ap_callback" << endl;

	if( (long) arg == 0xF00BA4)
	     printf("Callback for our statistics request: ");
	
	/* check for the event type and print out the statistics */
	if( ev->type == OSSO_IAP_STATISTICS)
                 printf(", time_active=%d, signal_strength=%d"
                        ", rx_packets=%d, tx_packets=%d"
                        ", rx_bytes=%d, tx_bytes=%d",
                        ev->u.statistics.time_active,
                        ev->u.statistics.signal_strength,
                        ev->u.statistics.rx_packets,
                        ev->u.statistics.tx_packets,
                        ev->u.statistics.rx_bytes,
                        ev->u.statistics.tx_bytes);
	else if (ev->type == OSSO_IAP_CONNECTED) {
		cout << "OSSO_IAP_CONNECTED" << endl;
	}
	else if (ev->type == OSSO_IAP_DISCONNECTED) {
		cout << "OSSO_IAP_DISCONNECTED" << endl;
	}
	else cout << "some event" << endl;	
}


I'm not sure am I missing something with the signals or with the callback.  
However I need to know when connection is ready (as to be able to handle  
OSSO_IAP_CONNECTED event).

All comments appreciated, thanks!
