This guide will instruct you to use NetWox R718DB Vibration Sensor in Easy LoRaWAN Cloud.

A. Basic Setup

Step 1: To read the full manual at the top of this guide.

Step 2: To turn on the node

  • Power on: Insert batteries (Users may need a screwdriver to open)
  • Turn on: Press and hold the function key for 3 seconds and the green indicator flash once.
  • Turn off: (Restore to factory setting) Press and hold the function key for 5 seconds and the green indicator flashes 20 times.
  • Power off: Remove Batteries.

Step 3: To get the keys of the node. We need Dev EUI and App Key for Easy LoRaWAN Cloud later.

  • Dev EUI: On the label at the back of the node
  • App EUI: To get from supplier/buyer
  • App Key: To get from supplier/buyer

B. Codec

Codec is used by the LoRaWAN Server in later guide to decode the message to suitable format for human and the Cloud.

Step 1: Uplink payload is mentioned in the Section 5 of the manual.

  • The manual is at the top of this guide.

Step 2: To get the codec of the node.

  • The codec is at the top of this guide.

C. Set MinTime and MaxTime

Step 1: To understand how MinTime and MaxTime work:

  • MinTime: The node will wake up every MinTime. If there is data change (Battery voltage change or vibration change…), it will send report data. Otherwise, it will go back to sleep.
  • MaxTime: The node will wake up and send report data even if there is no data change.

Step 2: To set a sample downlink payload to set MinTime = 1 min, MaxTime = 1 min and BatteryChange = 0.1v

  • Downlink fPort: 0x07
  • Downlink payload: 011B003C003C0100000000
  • MinTime: 2 bytes. Unit: second. => 003c (hex) = 60 (decimal) = 60s
  • MaxTime: 2 bytes. Unit: second => 003c (hex) = 60 (decimal) = 60s
  • BatteryChange: 1 bytes. Unit: 0.1v => 01 (hex) = 1 (decimal) = 1* 0.1 = 0.1v
  • Reserved: 8 bytes => 00000000
  • Hex to Decimal converter: here
  • Decimal to Hec converter: here

Step 3: To send a downlink command to the node to set the MaxTime and MinTime in step 2.

  • To use the guide here
  • Downlink payload and fPort are in Step 2.

Note: This node is LoRaWAN Class A. Therefore, it will only receive the downlink command after it sends data to the server.

  • It will receive downlink data from server every MaxTime or every MinTime (if there is data change) or when its button is pressed.
