Sensor states and state check

The sensor has four states: Initial, Joining, Configure and Operational state.

Re-join functionality

The device supervises its connectivity to the network, by monitoring that periodic downlink messages are 

received. 

The device tries to re-join the network if it has not heard anything from the network for 288 uplinks (~ 36 days). 

Startup Sequence

When the device has joined the network, startup transmissions are performed to make it easier to configure 

the device using downlink commands. When the startup sequence is completed normal operation is started.
