3 Measurement
The firmware differentiates between two main cycles / intervals:
•
TXT
•
MSI
A TXT interval forces the controller subsystem to wakeup, to take fresh sensor values and send these
data immediately to the respective receiver. The controller is going into deep sleep state afterwards.
The MSI forces also the controller subsystem to wakeip, to take fresh sensor values and qualify
whether pre-configured thresholds are violated or not. If none of the thresholds are violated, the
controller will enter deep sleep mode without sending anything. The thresholds can be either MIN or
MAX values or also DELTA values. The delta values are generated between the respective last and the
actual measurement and are positive [ abs() ]. If the threshold violation is healed, a 2
nd
telegram will
be sent in order to notify the receiver of this event as well.
A short MSI cycle with a long TXT cycle can therefore combine both, almost realtime data in case of
emergency or the need for alerting and longest battery lifetime.
