Connecting to a signal that does not have a pointer to the class

[weepdoo]

The problem with just a simple object (as you do create it) is that it will be destroyed when you will leave the current block (probably your method here).

So, you ask Qt to connect a signal from a object that is going to be destroyed.

What you could write might be something like:

#
xBeeComms *comms = xBeeComms(); // Object
#
...
#
connect( comms, SIGNAL( dataReceived( QbyteArray * ) ), this, SLOT( receivedData( QByteArray * ) ) ); // In the constructor 
 
delete comms; // <- really if you need it to be destroyed

#
xBeeComms *comms = xBeeComms(); // Object
#
...
#
connect( comms, SIGNAL( dataReceived( QbyteArray * ) ), this, SLOT( receivedData( QByteArray * ) ) ); // In the constructor 

delete comms; // <- really if you need it to be destroyed
