What LoRaWAN Class device the Sentrius RS1xx Sensor supports?

The Sentrius RS1xx LoRaWAN sensor has been designed to use as minimum power as possible to be able to run on batteries for years in the field. Class A has been naturally chosen to fulfil this aim as its the most power efficient class. The only downside of this will be on the downlink latency where messages from the network server will only be possible after an uplink from the sensor.

There is no way to enable Class B or C behaviour on the RS1xx sensor.
