3.4 3-Axis Accelerometer Capabilities
LW004-CT has built-in 3-Axis accelerometer sensor LIDSHTR.
The 3-Axis function is on by default. When the device moves, if it reaches the trigger threshold,
the device is considered to enter the movement status. In the movement status, the device will
periodically report the 3-Axis payload.
Customers can set
LIDSHTR’s
parameters and analyze 3-Axis payloads for additional application
development.
Note:
For the parameter setting of the 3-axis function, please refer to LW004-CT APP Guide.
3.4 Device Status Indication
Because of the impact of power consumption, LW004-CT is not designed to have a dedicated
indicator to indicate that the device is on.
Therefore, we have designed the device status to be briefly indicated by button triggering.
When the device is on, double click the on/off button twice within 1s,
Solid Green and keep one
second means that the device is on, otherwise the device is off.
Note:
When the on/off indication is triggered, the device will temporarily increase the broadcast
interval to 100ms at the same time, so that users can connect to the device faster via Bluetooth.
3.5 Device Information Upload
The device will periodically report the
Device Information Payload
. The default report interval is
4H.
The
Device Information Payload
contains mainly battery level, SOS Alarm Function Enable Switch
Status, MAC address and ADV name.
3.6 Battery Performance
The LW004-CT is equipped with a 540 rechargeable battery.
With batteries, typical lifetime in a close tracking scenario is around two days (Scan intensity:
medium, Report Interval:3 minutes).
3.7 Time Synchronization
There are two methods to
sync time through the MKLoRa APP or DeviceTime MAC Command
