RF24network Validate Node before Write?

I have a bunch of Nodes the Base (00) sends to and it all works fine.

But, if A Node goes offline for some reason (flat battery) I'd like to know we have lost contact with it.

Is there a simple method to pre-check a node is still available?
e.g.

  if (nodeActive(node021)
    { sendMsg(node021);
     } else
     { Serial.println(nodeMissingStr(node021));
     }

I looked through the .cpp files and ValidNode... only validates it is one of the pre-assigned Nodes and not whether it is active right now.

Would it be a solution to send a message to a node and see whether it is acknowledged?

Hmmm, kinda cumbersome method just for moving around the perch, don't you think?

I get the impression you have not worked with the RF24 Libraries.

But digging around in the .cpp files, I have solved the issue.

I have done a little work with nRF24 devices.

I (and others I am sure) would be very interested if you would explain how you solved your problem.
