Create yourself a namespace on shiftr.io

Download MQTT library from MQTT_in_Unity

Create a Unity Project (2019 version)

  • go to ASSETS --> Import Custom Pages --> Import the Mqtt Package you just downloaded to your Unity project
  • Go to Project Window --> Assets --> MQTT --> Scripts --> Test → delete TestScript. Create a new Script with the following Code (name it mqttShiftrIO):

  • Create an empty game object and put the mqttShiftrIO script on it
  • go to the name space of Shiftr.io → click on Token
  • Check your Key(Username)

Secret(Passwort) and transfer to Unity editor --> you can change the message that is shown in the inspector in the mqttShiftrIO

  • Topic subscribe → you can change the number of topics you subscribe to
  • delay (100) --> the amount of data that is send to shiftr.io is still in it's converting rate
