Note:
The interval between shutting down twice or power off/on is suggested to be about 10 seconds to
avoid the interference of capacitor inductance and other energy storage components.
4.2 Join Into Lora Network
To join the device into LoRa network to communicate with LoRa gateway.
The network operation is as following:
(1)
If R718DB2 had never joined any network, turn on the device; it will search an available LoRa
network to join. The green indicator will stay on for 5 seconds to show that it joins into the network,
otherwise, the green indicator does not work.
(2)
If the device had been joined into a LoRa network, remove and insert the batteries; it will repeat
step (1).
4.3 Function Key
(1)
Press and hold function key for 5 seconds to reset to factory setting. After restoring to
factory setting successfully, the green indicator will flashes quickly 20 times.
(2)
Press function key to turn on the device which is in the network and the green indicator will flash
once and the device will send a data report.
4.4 Data Report
When the device is powered on, it will immediately send a version package Report and a report data
with spring trigger status and battery voltage value.
The device sends data in the default configuration before any configuration is done.
Spring Trigger (Two ways): as long as the device feels vibration and the spring is deformed, an
alarm message will be issued.
The vibration alarm bit is "1"; the stationary, unshaken alarm bit is "0".
Battery voltage default report value: mintime = maxtime = 3600s, reportchange = 0x01 (0.1V).
Note: MinInterval is the sampling period for the Sensor. Sampling period >= MinInterval.
Remarks:
1. The device data sending cycle depends on the burning configuration before shipment.
2. The interval between two reports must be the minimum time.
