# Intro

--------

WolkLoRa repo consists Arduino IDE example which makes connection to [The Things Network](https://www.thethingsnetwork.org/). It's based on [RN2483-Arduino-Library](https://github.com/jpmeijers/RN2483-Arduino-Library).

Device measure enviroment temperature data on hearbeat event. This data can be routed from TTN to [WolkAbout IoT Platform](https://demo.wolkabout.com/#/login) using apropiated decoder(below described as [Application Decoder](#decoder)) and WolkAbout IoT Platform wizard.

# Prerequest

-----

**Used Hardware:**

 * [Arduino UNO](https://store.arduino.cc/usa/arduino-uno-rev3)

 * [Mikroe LoRa click - RN2483](https://www.mikroe.com/lora-rf-click)

 * [DS18B20 Temperature Sensor](https://eu.mouser.com/ProductDetail/Maxim-Integrated/DS18B20%2b?qs=sGAEpiMZZMvbyeSUH4qH%2fLbikZ7SIep9)

**Firmware dependencies:**

 * Install following Arduino libs([HOW TO](https://www.arduino.cc/en/guide/libraries)):

   * OneWire

   * DallasTemperature

 

 * Include files:

   * src/rn2xx3.cpp and src/rn2xx3.h with *Sketch/Include Library/Add .ZIP Library...* in Arduino IDE. Original source is [RN2483-Arduino-Library](https://github.com/jpmeijers/RN2483-Arduino-Library).

# Example of usage

------

## Hardware Connection

![wolkttn-connection-small](https://user-images.githubusercontent.com/10706360/46349830-73ab6e00-c653-11e8-9221-56c1213d41a8.png)

## Firmware Deployment

* Open one of *WolkNode_TTN.ino* example

* **#define** LoRA connection mode, **OTAA** or **ABP**

* Insert your TTN device parameters. Copy *Example Code* from device overview into WolkNode_TTN.ino

* Verify and Upload to device



# Application Decoder

-----



To route data from TTN to WolkAbout IoT Platform create device on WolkAbout IoT Platofrm and copy following decoder into ***Payload Formats*** section on *TTN Applications*. Note that name of methode *'.T'* over *var decoded* is *REF* from device manifest on WolkAbout IoT platform.

```

function Decoder(bytes, port) {

  // Decode an uplink message from a buffer

  // (array) of bytes to an object of fields.

  var decoded = {};

  var type = bytes[0];

  

  switch (type) {

    case 1:

      decoded.T = bytes[1] + bytes[2]/100;

      break;

    default:

      decoded.T = bytes[0];

  }

  

  return decoded;

}

```
