Temperature-controlled reporting interval
In HVAC (heating, ventilation, air conditioning) applications it might be desirable to receive
status updates more often if the measured temperature is significantly above or below the
target value.
Figure 4 below illustrates the use of the temperature-controlled reporting interval.

Temperature-controlled reporting interval
STM 550 can use the temperature measured by the temperature and humidity sensor to
trigger a higher update rate. To enable this feature, use the following steps:
1.
Make sure that the EEP selected using the EEP register as described in chapter 9.5.8
reports the measured temperature
2.
Configure the desired temperature threshold using the TEMPERATURE_THRESHOLD
register described in chapter 9.5.23
3.
Configure the desired reporting interval using the TEMPERATURE_TX_INTERVAL reg-
ister described in chapter 9.5.24
4.
Enable the use of the defined parameters using the TEMP SENSOR bit field in the
THRESHOLD_CFG1 register of the NFC interface as defined in chapter 9.5.13.
Consider the available energy before lowering the reporting interval as discussed in chapter
2.3.1.
