Get the name of the current network operator.
The return value is a string which may be blank if the device is still trying to find a network, otherwise it is the name of the network operator being used.
Where DroneCell is the name you have given to the device in Project Designer.
Example (assuming you have called your device myDroneCell in Project Designer):
// Write name of the operator to the output
cout << "Operator=" << myDroneCell.getOperator();
