The specific cluster is available by the manufacturer code 0x10B9.
Managed attributes as follows:
Attribute Attribute
ID
Type Description
ManualFunction 0x0000 bool 0 : Emergency call management disabled
1 : Emergency call management actived
Value manufacture : 1
FallFunction
0x0001 bool 0 : Fall detection management disabled
1 : fall detection management actived
ThresholdFreeFall 0x0100 uint8 Free fall detection threshold (62.5mg/LSB).
The acceleration on all axes is compared to this value to determine a free fall.
. Value between 0x05 and 0x09 (300mg à 600mg) is recommended
Value manufacture: 0x09
TimeFreeFall 0x101 uint8 Temporal threshold of characterization of a free fall (5ms/LSB)
This is the minimum time during which freefall detection is detected. A value between
100ms and 300ms is recommended (0x14-0x46).
Value manufacture: 0x15
ThresholdInactivity
0x0102 uint8 Threshold of characterization of inactivity (62.5mg/LSB)
Value manufacture: 0x03
ThresholdDeltaVectorSum 0x0103 uint16
Characterization value of a position change:
With characterized by the difference of acceleration of an axe between the
beginning of detection of the free fall and the end of the fall and g = 0xFF
Example: 0x7D70 correspond to a difference of place of
Then, more ThresholdDeltaVectorSum ist low less the position change is think about
by the algorithm of fall detection. A threshold of value 0x0000 nn long takes count of
the finale position of the wristband.
Default value: 0x01F4 (500)
NoMovementTime 0x0104 uint8 Characterization of idle time after a fall in seconds.
Value between 0 et 10s is recommended
A value 0s takes account of types of fall
A value of 10s takes account only the heavy falls (the person is unconsciente and
doesn’t move)
Default value: 0x00
take account of type of falls
ApplyButtonTime
0x0105 uint16
Time threshold for taking into account pressing the emergency
call button in milliseconds
Default value: 0x C8 (200ms)
Taking account the absence of move after the fall detection is interpreted as follow by the algorithm of the ZCare:
1) If attribute NoMovementTime = 0 : the fall is directly validated, an order type
ZoneStatusChangeNotification is done with alarm1
2) If attribute NoMovementTime > 0, the algorithm will look for a tomporel window of ( NoMovementTime *
1.5) seconds a period of inactivity of NoMovementTime seconds.
a. If a none activity is detected then an order type
ZoneStatusChangeNotification
is donce with an
alarm1
b. If not, the fall is not detected, it is considerate that the person who has potentially fall can use the
emergency fall button if necessary.
