Step 4: Upload Code to Your Host Microcontroller
The Alexa Connect Kit (ACK) Device SDK provides source code that you use in your device's Host Microcontroller application. In this step, you upload the AlexaConnectKit_HelloWorld sample application to your host microcontroller.
Your development board and your Arduino Zero might not be physically connected. If they are not connected, physically connect the two boards, and connect the Micro-USB cable that came with the kit to the Arduino Zero Programming Port. For details, see Physically Connect the Boards.
Upload code to your Host Microcontroller
To upload code to your Host Microcontroller, follow the instructions in Upload Code to the Arduino Zero. The instructions explain the process by using the Development Kit for ACK, but you can complete the steps with your own host microcontroller.
