QBluetoothSocket::readyRead signal is not emitted

QT Project

Hello,

This is regarding QBluetoothSocket. I am able to connect to the device. I am trying to send data to device and read it.

The read api returns 0.

The readyRead signal is not emitted.

Any suggestion / pointer will be useful.

Thanks

void ConnectedToServer()
{

qDebug() << "Connected server peername " << mBluetoothSocket->peerName();
qDebug() << "Connected server peer port" << mBluetoothSocket->peerPort();
qDebug() << "Connected server peer Address" << mBluetoothSocket->peerAddress();
QString message;
message = "test";
qDebug() << "Sending message " << message;
sendMessage(message);
mBluetoothSocket->waitForReadyRead(-1);
readSocket();

}

void readSocket()
{
if (!mBluetoothSocket)
return;
qDebug() << "readSocket" << mBluetoothSocket->peerName();
qint64 ret;
char data[256] = {0};
ret = mBluetoothSocket->read(data,100);
qDebug() << "Data " << data;
qDebug() << " read ret " << ret;
while (mBluetoothSocket->canReadLine()) {
QByteArray line = mBluetoothSocket->readLine();
qDebug() << "readSocket data " << line.constData();
}
}

void sendMessage(const QString &message)
{
qDebug() << "sendMessage";
qint64 ret;
QByteArray text = message.toUtf8() + '\n';
qDebug() << "sendMessage" << text;
ret = mBluetoothSocket->write(text);
qDebug() << "Return value" << ret;
}
