2.6. LoRaWAN Class C

The DRY CONTACTS IP68 LoRaWAN 863-870 device is delivered with a Class A configuration by default but can be switched to a Class C con-
figuration. The Class C enables the device to listen permanently the network in order to receive more quickly any downlinks (no need to wait for
an uplink to push a downlink). For example, in this mode it possible to change remotely the state of an output at ant time.
PAY ATTENTION: this mode can be activated only if the device is powered by an external supply.
When the device is running in Class C, if there is a power failure the device activates a "backup mode" (explain here under) to conserve data
and send it again when power supply is turned ON:
