Static, active
threshold
The active threshold can be changed by the gateway issuing a command;
Active activity threshold range is 0x0003-0x00FF (default is 0x0003);
Active threshold
The scale factor of the threshold is 62.5 mg, and g is the gravitational acceleration at standard
atmospheric pressure.
The Inactive static threshold can be changed by the gateway issuing command;
Inactive static threshold range is 0x0002-0xFF (default is 0x0002)
Static threshold
The scale factor of the threshold is 62.5 mg, and g is the gravitational acceleration at standard
atmospheric pressure.
if you need to set the active threshold to 10m/s², you need to set the value to 10/9.8/0.0625=16.32.
Example
The last value obtained is an integer and is configured as 16.

Example of threshold configuration:
Assuming that the active threshold is set to 10m/s2, the value to be set is 10/9.8/0.0625=16.32. The last value obtained is an integer and is configured as 16.
Assuming that the active threshold is set to 8m/s2, the value to be set is 8/9.8/0.0625=13.06, and the last value obtained is an integer and is configured as 13.
Configure device parameters ActiveThreshold=16, InActiveThreshold=13
