      LoRa Node

      LoRa is used for long-range communication between devices and gateways, ideal for sensors and devices that require low bandwidth and power consumption, such as agricultural sensors or urban infrastructure monitoring.

      Outputs

      The LoRa node will output each device’s payload in the order that they are received.

      How to Use

      Implementation

      In the Rayven Workflow Builder:

      • Select Inputs.
      • Drag the LoRa node to the canvas.
      • Provide an input to the LoRa node by connecting it to another node.
      • Double click on the LoRa node to open the configuration window.

      Configuration

      Section: General

      This section contains basic configuration elements required for any LoRa node implementation

      Field

      Requirement

      Comments

      Node Name

      Mandatory

      Enter a name for this node.


      This provides a handle to which you and others can refer, so it should be simple but meaningful and explain the node’s purpose.

      URL

      Autofilled

      This unique URL points to the Rayven server and can’t be changed.


      Example of URL: https://my.rayven.io:8082/api/main?uid=2853d58a545859b144fb91142604bc14149d

      Payload Format

      Mandatory

      Select the format of the payloads from the dropdown menu

      • Key:Value
      • Comma Separated Key:Value
      • As is (Do not convert to JSON)


      Section: Advanced Features

      Field

      Requirement

      Comments

      Payload Device ID Field Name

      Optional

      Optional parameter. It is possible to send the unique device ID in the payload. To do this, enter the field name in the payload that contains the device ID.

      Pass Entire Payload

      Optional

      If the checkbox is selected, the node will output the entire JSON and the decoded data of the "payload" field. For example, if the LoRa input is:


      [{"rx": {"moteeui": "2939CEC4", "userdata": {"seqno": 5, "port": 2, "payload": "NzQ2ZDVmMzEzMDNhMzIzNTJlMzM=", "motetx": {"freq": 915600000, "modu": "LoRa", "datr":              "SF12BW125", "codr": "4/5"}}, "gwrx": [{"time": "2019-12-24 19:44:40", "chan": 2, "rfch": 0, "rssi": -85, "lsnr": 7.7999999999999998}]}}]


      Then if 'Pass entire payload' is unchecked (default state) the node will output only the decoded data of the "payload" field: "NzQ2ZDVmMzEzMDNhMzIzNTJlMzM="


      The output will be: {"tm_10":"25.3"}


      If 'Pass entire payload' is selected the node will output the entire JSON and the decoded data of the "payload" field.


      The output would be:


      {"rx":{"moteeui":"2939CEC4","userdata":{"seqno":5,"port":2,"payload":"NzQ2ZDVmMzEzMDNhMzIzNTJlMzM=","motetx":{"freq":915600000,"modu":"LoRa","datr":"SF12BW125","codr":"4/5"}},"gwrx":[{"time":"2019-12-24 19:44:40","chan":2,"rfch":0,"rssi":-85,"lsnr":7.8}]},"payload":{"tm_10":"25.3"}}

      Activation

      Once the node has been configured, click the Activate button and then click Save. The node is ready to receive data into the workflow.
