PingPong without gateway or controller?

I am trying to test RFM95 radios. So far I can not get any communication between them. I would like to be able to test without having to worry about a gateway or controller. I just want to get communication of some kind between the two nodes. I have tried the Example sketch PingPongSensor, but it is going through the process of trying to communicate upstream:

It never gets to presentation() or loop().
Is there some easy way to let the test go forward with needing a gateway controller? Since the sketch later sets the nodeId to with 200 or 201 and there is no need to communicate upstream for the simple purpose of a ping, I don't see a need for a gateway or controller to be present for this test.

@gohan confirmed one of my guesses. I made some further guesses as well. I hard coded a node ID, disabled the uplink check, hard coded a parent ID and defined it as static. All of this seems to have gotten the node to be independent.
One of the consequences of my modifications is that entering "0" or "1" in the terminal no longer has any real effect. Below is the output, including the results of me entering "T" from the serial monitor at the end.

The sketch works using a direct, wired connection (RS485).
T received - starting test... Sending Ping to Ying Node 2226167 TSF:MSG:SEND,201-201-1-200,s=1,c=1,t=24,pt=5,l=4,sg=0,ft=0,st=OK:2226165But it does not work with my RFM95's, but that is a completely different topic.
