Calendar Events
The Range Extender features an embedded Real Time Clock (RTC) which needs to be synchronized for proper operation. This
synchronization can be handled over the LoRaWAN network per Calendar Event or via local configuration interface. Due to the fact that the
®
clock crystal frequency can drift over temperature it is recommended to synchronize via LoRaWAN from time to time (e.g. once per week).
®
Calendar Events are used to define the runtime behaviour of this application. Up to 32 Calendar Events for different actions can be
configured.
A single Calendar Event item consists of the following three or four elements:
Event Type
The event type defines the kind of action to be performed.
Repetition Type
The repetition type defines the periodicity of an event e.g. monthly, every 2 weeks, daily, every 4 hours or none.
Date / Time
The date / time element defines when the event should be scheduled e.g. day of month, day of week, hour, minute and second.
Filter Set ID
This element defines a filter set which is active during a Wireless M-Bus reception phase.
Note: this element is currently only used for Wireless M-Bus reception event types. A value of 255 (0xFF) is reserved and means
that all configured Wireless M-Bus filters should be applied.
