2.4.7
Magnet contact sensor-controlled reporting interval
If a door or a window is opened when it normally should be closed (or vice versa), then it
might be desirable to receive status updates more often to monitor its status. STM 550x can
therefore be configured to use a lower reporting interval, i.e. a higher update rate, for one
of the two magnet contact sensor status options (open or closed).
Figure 10 below illustrates the use of the magnet contact sensor-controlled reporting interval.

Magnet contact sensor-controlled reporting interval
STM 550x can use the status of the magnet contact 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 8.5.8
reports the magnet contact status
2.
Configure the desired reporting interval using the MAGNET_CONTACT_TX_INTERVAL
register described in chapter 8.5.22
3.
Select the state of the magnet contact (open or closed) where the lower update in-
terval should be active using the MC SENSOR bit field in the THRESHOLD_CFG2 reg-
ister as defined in chapter 8.5.14.
Consider the available energy before lowering the reporting interval as discussed in chapter
2.4.1.
2.4.8
Arbitration between reporting intervals
If more than one condition for a lower reporting interval applies
–
e.g. both an acceleration
exceeding the acceleration threshold is detected and the room is brightly lit in excess of the
light level threshold
–
then the lowest of the corresponding reporting intervals will be se-
lected.
