How to configure the frequency of measurements and messages

One of the most common configurations a user would like to change is the frequency of the measurements taken by the sensor and the frequency of the messages the end user receives. To accomplish this, the user must generate a downlink (which can be done using the ) and send it to the device via their LoRa Network Server (LNS).
On the Application Configuration tab, the field Temperature Measurement Interval Seconds defines how often the sensor takes a measurement, and the field Periodic Event Message Interval establishes after how many measurements the transmitter sends data over LoRa.
Thus, the frequency of the messages is determined by Temperature Measurement Interval Seconds multiplied by Periodic Event Message Interval. For example, above the Temperature Measurement Interval Seconds is 900 seconds and the Periodic Event Message Interval is 16, which means that the frequency of the data messages will be 14400 seconds, equivalent to 4 hours.

On the Sensortab, the field Measurement Interval Minutes defines how often the sensor takes a measurement, and the field Periodic Event Message Interval establishes after how many measurements the transmitter sends data over LoRa.
Thus, the frequency of the messages is determined by Measurement Interval Minutes multiplied by Periodic Event Message Interval. For example, above the Measurement Interval Minutes is 5 minutes and the Periodic Event Message Interval is 12, which means that the frequency of the data messages will be 60 minutes, equivalent to 1 hour.
On the Sensor tab, the user can also select the operating mode of the event messages. This can be:
extended: sends the maximum, minimum and average values of the measurements taken.
min_only: sends only the minimum value of the measurements taken.
max_only: sends only the maximum value among the recorded measurements.
avg_only: sends only the average of the measurements taken.
