Downlink Messages
The downlink message (web application to sensor) specific to the sensor configuration is
defined in following table. The common downlink messages are not included in this section
(see common messages document).

Defined by Mode selection
A Mode setting of 0x00 selects Threshold Mode (default) and a setting of 0x01 selects Report-
on-Change mode. This selection defines bytes 3-6 as shown in the sections below.

Periodic Reports
The tilt sensor can also send periodic updates, and this is defined in byte 1 of both
modes. A setting of 0 will disable periodic reporting. The period is defined in 1-hour
increments when the most significant bit is 0, and it is defined in 1 minute increments
when the most significant bit is 1 as shown in the following table.

The shape and magnitude of the temperature-dependence curve will be
different depending on the orientation of the sensor. Thus, this curve
alone should not be used for temperature compensation.
