Downlink Messages

Downlink messages are from the cloud to the sensor and are used to configure the sensor. The sensor initiates
downlink messages, since the sensor is typically sleeping with the radio turned off.
For LoRaWAN devices, a downlink can be received after any uplink within the receive window.
The following messages can be sent back to the sensor upon a downlink request.
