Hi David,
we have reduced the number of examples to have a lower workload while maintaining the sketches.
I can understand that your problem is on the radio side as your command reach the Gateway but is not passed to the Node, I honestly don't rember if Moteino radio has an ack-retransmit method in hardware as other radio, this as vNet it self doesn't carry any check on this.
So, if you see the output message on the Gateway but this doesn't became an input on the Node, so is a transmission problem and radio can have problem like those.
Regards,
Dario.
