Connect to LoRaWAN Server

Currently HRU-3601 uses LoRaWAN a communication protocol, and this topic aims to describe how HRU-3601 can be connected to LoRaWAN Server.

Seting up LoRaWAN Gateway

Before that, make sure there is a LoRa Gateway active in your TTN/TTS account.

Confirm configuration information

The details of the introduction of each parameter are as follows:

  • network access mode choose OTAA.

  • devEui Your node ID, you can fill in your own, in this case we’ll write “2233445566778898”.

  • appEui Feel free to fill it out. Here we’ll write “0000000000000000”.

  • appKey Feel free to fill it out. Here we’ll write “88888888888888888888888888888888”.

  • appIxDutyCycle unit:S the transmission interval of the LoRa signal.

  • appPort Feel free to fill it out. Here we’ll write “1”.

  • channel start Align with the gateway.

  • channel end Align with the gateway.

Tip

If you are not familiar with LoRaWAN, try to choose the default and set a simple EUI and KEY.

Registering node on server

Register a new device in TTN or TTS “Applications”,chooseEnter end device specifics manually.

Select the frequency plan, and fill in the corresponding AppEUI, DevEUi, AppKey, and register the device.

Tip

The joinEui here is the AppEui on the configuration page, which is “0000000000000000”.

After registration is complete, if all is well, you will see the device active.

Click payload formatters, select Custom Javascript formatter, and enter decoding at the position in the figure. Download the decoder here: HRU-3601 Related Resources.

Important Hints

Please double check the following two things:

  1. The LoRaWAN parameters is the same as server!

  2. The listening frequency of your LoRa Gateway is the same as LoRa node’s sending frequency. We strictly follow LoRaWAN™ 1.0.2 Regional Parameters rB;
