// succeed without actual configuration. In both cases, if you
// are actually attempting to join a real LoRaWAN network, you
// must change the parameters below to match the network you are
// attempting to join.
// For OTAA, you need to supply valid Device EUI, Application EUI,

// sensor.setDeviceEUI("0011223344556677");
