Android QBluetoothSocket::SocketError( 8 )

bnogal

That is the error i get... for the last 2 weeks.

I am trying to comunicate two devices to try the new characteristic... but i cant make it work.

basically
I register one as a server
@
rfcommServer = new QBluetoothServer(QBluetoothServiceInfo::RfcommProtocol, this);
connect(rfcommServer, SIGNAL(newConnection()), this, SLOT(clientConnected()));

connect(rfcommServer,SIGNAL(error(QBluetoothServer::Error)),this,SLOT(serverError(QBluetoothServer::Error)));
rfcommServer->listen(QBluetoothUuid(SERVICE_UUID),SERVICE_NAME);
@

The other lookup for services... and is discovering it... and i try to connect using:
@
QBluetoothSocket* socket = new QBluetoothSocket(QBluetoothServiceInfo::RfcommProtocol);
socket->connectToService(serviceInfo);
@
but connection fails, throwing the error : QBluetoothSocket::SocketError( 8 )

Any idea?

Thx!

Hi,

Are you using Qt 5.3 ? If not, you will need to, the bluetooth module for android has been ported for this version of Qt

yes, i am trying the 5.3.0 beta version.
But as it is my first time using the bluetooth module, i dont really know if i am doing something wrong or there are limitations in the android version.

Someone got the examples working?

Ok, i am going to self respond, as finally i got it working.

@
//socket->connectToService(serviceInfo);
socket->connectToService(serviceInfo.device().address(),QBluetoothUuid(SERVICE_UUID));

Seems that call to connecToService with the serviceInfo that you got during discovering is not working. I think it must be a bug (we talk about 5.3.0beta) so i am going to leave it report. :)

Thx anyway :)
