[Solved] Bluetooth Printing using Qt

[seethanellai]

Hi,

I am having one android app with printing facilities. I am able to print through ethernet printing.
But now i want to print using bluetooth printers (Bixolon SRP 350 plus). I have search it in google. I am unable to find the proper guidance.

I have checked QtBluetooth , but it says

"Push files to remote devices using the OBEX Object Push Profile (OPP) - Object Push Profile is not supported on Android."

Anyone have idea on this, Please help me with this.

Is it possible in Qt C++? Without calling java methods?

This is achived by QBluetoothSocket. Done.

Nice !

Would you mind sharing your solution ? That might help other people :)

Sure. Below is the code snippet..
@
/* Connect to blue tooth socket with the proper MAC address and unique uuid. UUID can be created through QBluetoothUUID */

// Connect to service
static const QLatin1String serviceUuid("00001101-0000-1000-8000-00805F9B34FB");

m_pBtSocket = new QBluetoothSocket(QBluetoothServiceInfo::RfcommProtocol);

    QBluetoothAddress address = QBluetoothAddress("74:F0:7D:E2:23:44");
    m_pBtSocket->connectToService(address,QBluetoothUuid(serviceUuid),QIODevice::ReadWrite);

//Connect to the signal.
connect(m_pBtSocket, SIGNAL(connected()), this, SLOT(connected()));
connect(m_pBtSocket, SIGNAL(disconnected()), this, SLOT(disconnected()));

//Once it is connected to the printer then send text to it
void bluetoothprint::connected()
{
m_pBtSocket->write(text);
m_pBtSocket->write("\n\n\n\n\n\r");

m_pTextEdit->append("Connected: " + m_pBtSocket->peerName());

}

void bluetoothprint::disconnected()
{
m_pTextEdit->append("disconnected");
}

Hi, Thank you for sharing your code.
Just wanted to know if the above mechanism can work for any printer or it is printer specific?
With the reference of your code, i am able to connect to various printer models but I am not able to print the text using write().
