Is there any way to detect an offline Node?
Currently all I get is a single "Failed to Send" message. I have added 5-retries and timeout to the send, so it becomes a little more visually obvious in the Terminal, not very elegant but works to let me know the Node is offline. I would like to be able to test if the Node is available.
I checked the RF24network.cpp and there is a "is_valid_address(header->to_node)" mentioned but it just tests to see if the Node number is valid within the network and not if it is online or not.
Is there a option to test for a node-online? How?
