Extract

Download한 arduino-mqtt-IPv6.zip을 복사하여 Arduino 사용자 Library 경로에 붙여 넣습니다.

Copy an arduino-mqtt-IPv6.zip downloaded and paste to Arduino User Library directory.

arduino-mqtt-IPv6.zip의 압축을 풀고, 이름을 arduino-mqtt로 변경합니다. arduino-mqtt의 이름으로만 사용할 수 있습니다.

Extract an arduino-mqtt-IPv6.zip and rename to arduino-mqtt. The directory name must be arduino-mqtt.

압축을 풀고 이름을 바꾼후 Tree view는 아래와 같습니다

The following is tree view after extracted and renamed.

그리고 test.mosquitto.org를 통해 W6100EthernetShield 예제에서 publish한 메세지를 볼 수 있습니다.

And you can see the message from test.mosquitto.org which W6100EthernetShield published.

How to use Arduino Ethernet Library IPv6 (WIZnet Ethernet Library)

Tue, 07 May 2019 15:00:00 +0900

Arduino Ethernet Library - Default

You already installed Arduino IDE, you can use Ethernet Library as default.

Just you can run the Arduino IDE, and Choose File -> Examples -> Ethernet -> AdvancedChatServer.

The following is default Ethernet Library Example AdvancedChatServer.

The default Ethernet Library are located on “C:\Program Files (x86)\Arduino\libraries\Ethernet”

And the default User Library are located on “C:\Users'Your ID’\Documents\Arduino\libraries”.

WIZnet Ethernet Library - Arduino Ethernet Library IPv6

Download

Go to the WIZnet Ethernet Github and choose the IPv6 branch.

WIZnet Ethernet Library IPv6

If you don’t want to use any git client, you can choose Download ZIP.

No sign-in required and no sign-up required.

Extract

Copy Ethernet-IPv6.zip downloaded and paste to Arduino User Library directory.

Extract Ethernet-IPv6.zip and rename to Ethernet. The directory name must be Ethernet.

The following is tree view after extracted and renamed.

Run

Now you can run the Arduino IDE and just Choose File -> Examples -> Ethernet -> AdvancedChatServer.

You can see the AdvancedChatServer of WIZnet Ethernet Library(Arduino Ethernet Library IPv6).

After Upload, you can see the network information messages via Serial Monitor.

The IPv6 is yours now.

Trouble Shooting

Ethernet shield was not found

If you see the message of “Ethernet shield was not found.”,

You probably use the MKRVIDOR-4000(or use not supported board on Ethernet Library).

If you are, you should add your board on Ethernet Library.

Open the w5100.cpp, are locaed on “C:\Users'Your ID’\Documents\Arduino\libraries\Ethernet\src\utility”.

The MKRVIDOR-4000 is not added yet in Ethernet Library as default.

You should add the MKRVIDOR-4000 like below shown and save a file the w5100.cpp.

IoT iOffload Design Contest

“IoT iOffload Contest” is an international project contest for developers worldwide, powered by WIZnet. This contest gives developers an opportunity to showcase their skills in IoT innovation and competency.

For the first time in the world, “IoT iOffload Contest” is using hardwired TCP/IPv6 to developes new opportunity. If you want to learn more about IPv6 and hardwaired TCP/IPv6, please refer these documents; What is TCP/IPv6, How to use hardwired TCP/IPv6.

We can’t wait to see what you make!
