1.5. Run the Blink Example

You are now ready to run your first example on the LinkIt Smart 7688 development board. This

example switches the board’s Wi-Fi LED on and off every half second.

Quick steps:

• Execute the example in system console

• Watch the LED blink on the board

• Terminate the example

Next: Connecting to the Internet.

Step-by-step

Step 1: Run the blink example in LinkIt Smart 7688 system console

In the system console, type following command to run the blink example in Python:

# python /IoT/examples/blink-gpio44.py

Step 2: Watch the Wi-Fi LED blink

The Wi-Fi LED on LinkIt Smart 7688 should start to blink every half second.

Step 3: Terminate the blink example

In the system console, type CTRL + C, this will terminate the example.

You can now explore the system console and try other examples or Linux command utilities – but

before that, it’s important to connect the board to the Internet first. You can do that by

connecting the board to a Wi-Fi Access Point that has Internet connection. The steps are

described in the next section.
