DO NOT deliver raw values (acceleration G value in time domain) and parameters in frequency domain (FFT function).
1.3 When does device send Uplink messages?
The device will send uplink messages in the following cases:
Case 1: After power-up in the 60s, the device will send the first message called START_UP. The payload will tell the user the HW version, FW version, and current configuration of the device;
Case 2: Then, in every interval time (pre-configured), for example, 10 minutes, it will send the message called CYCLIC_DATA. The payload will tell the user the following data like measured values, battery level, and alarm status...
To change the cycle of data sending, you can change the value of the parameter: CYCLIC_DATA_PERIOD.
Case 3: If ALARM_ENABLED=1, the device will send ALARM message immediately when device switches from Normal state to Alarm state. It will repeat sending ALARM messages in predefined ALARM_PERIOD time interval (default is 10 minutes) if the Alarm state still exist;
Case 4: During the commissioning, testing, or calibration sensor, the user can force the device to send the uplink message to get the data immediately. This message is called FORCE_DATA. The payload will provide data like raw measured value, scaled measured values, battery level, and alarm status... It can be forced by applying the magnet key on the reed switch in 1s;
Case 5: If users want to change the configuration immediately, they don't need to wait until the next cyclic data-sending message; instead, they can force the device to send a special uplink message so that the device can get the new downlink message. This uplink message is named PARAMETERS_UPDATE. It can be forced by applying the magnet key in more than 5s.
Case 6: In every interval time (pre-configured), for example, 24 hours, it will send the message called HEARTBEAT. The payload will tell the user the following data like hardware version, firmware version, current sensor configuration

Principle of operation
Most of the time, the device will be in sleep mode. When the timer reaches the Measure_Period (for example, 30 minutes), it will wake up the device to start the measurement.
*** This Measure_Period will affect the energy consumption of the device.
The measurement will take a certain time to finish; it can take milliseconds or seconds to finish the measurement. This measurement time depends on sensor type, required accuracy, and other factors. Shorter measurement time, lower energy consumption, and longer battery life.
After finishing the measurement cycle, the device can read all the measured parameters.
Main parameters for alarm are VELOCITY RMS
If parameter ALARM_ENABLE = 1
Then the device will compare the main parameter with HiHi_Alarm_setpoint and Hi_Alarm_setpoint together with Hysteresis to define the state of the device is No_Alarm or Hi_Alarm or HiHi_Alarm.
*** Hysteresis value is to avoid the flickering status (Alarm/No-Alarm toggling quickly) when the measured value close to alarm threshold.
If X-axis is in Blue color area of above graph, the device is in Normal or No_Alarm state;
If X-axis is in Red color area, the device is in HiHi Alarm state (Alarm 2);
None of above 02 states, the device will be in Hi Alarm state (Alarm 1).
How the device send uplink message base on above 03 states?
If Device state is No_Alarm, it will check the timer to reach the Cyclic_Data_Period to send the CYCLIC_DATA uplink message;
If Device state is changed from No_Alarm to Hi Alarm or HiHi Alarm, it will send alarm message immediately. Please check the below picture to understand the operation flow when finishing the measurement cycle:
Once alarm happened and send the first alarm message, the device will send the next alarm message in the Alarm_Period if the device is still in Alarm states (Hi Alarm or HiHi Alarm). Please check below picture to understand the operation flow when the Alarm timer reaches the Alarm_Period.
If parameter ALARM_ENABLE = 0
The device will check the timer to reach the Cyclic_Data_Period to send the CYCLIC_DATA uplink message.
Please check the Payload document to understand clearly about uplink messages, downlink messages, meaning of parameters for configuration...
