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

Refer to Quick Start to go to the configuration page of HRU-3601.


In order to explain the corresponding positions of various parameters in the server, we will fill in the specific numbers here, and please fill in the actual use according to your own needs.

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

  • network access mode choose OTAA or ABP, .

  • devEui Your node ID, you can fill in your own, must be 16 hexadecimal digits, such as “2233445566778898”.

  • appEui Feel free to fill it out, must be 16 hexadecimal digits, such as “0000000000000000”.

  • appKey Feel free to fill it out, must be 32 hexadecimal digits, “88888888888888888888888888888888”.

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

  • appPort free choice.

  • channel start channel end Align with the gateway, For example, if you want to select 0~7, fill in 0 and 7.

  • loraWanClass The communication mode of LoRaWAN, we can choose CLASS A or CLASS C.

  • isTxConfirmed Uplink receives confirmation whether it is enabled or not.

  • adr Whether data rate adaptation is enabled.


The above is the configuration page in OTAA mode. If ABP needs to be used, the configuration will be slightly different.

Registering node on server

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

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


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.

Click Save change and move the mouse to the uplink data output to view the data uploaded by HRU-3601.

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;
