The << operator is an overloaded operator used in C++ stream IO. In basic terms it takes whatever object or value is on the right hand side of the operator, converts it to a string (aka char*) and sends that to the stream object on the left hand side. So using the standard ouptut stream (console), you can do:
C++
int number = 23;
double half = 23 / 2;

std::cout << "value = " << number << " halved = " << half; 

So assuming the items in your code are:
C++
char* command = " hcitool ";
QString string = " dev ";

the result of:
C++
QP->start("/bin/sh", QStringList() << "-c" << command << "-c" << string );

should be:
"/bin/sh -c hcitool -c dev"

sent to the process handler.

Maybe you should spend some more time studying C++, as well as QT.
