Avert your eyes! Unless you enjoy staring into bright, white strobing lights.

Similar warnings about white strobing lights.

If all goes well, there should be a very short green blip of the LED, followed

by a few blinks of red and orange. When the imp starts blinking green once

a second, you know you’ve got your imp commissioned yay!

Troubleshooting

If you’re imp isn’t yet in the blinky green phase, use the LED blink codes to

find out where it’s failing. Here are some recommended steps, depending

on the failure point:

• Connecting to the server (orange, red, off) - Make sure there’s no

firewall blocking the imp’s way to the Internet (and make sure your

WiFi network has an Internet connection in the first place).

• Getting IP address via DHCP (red, orange, off) - Double check your

WiFi password.

• Attempting WiFI connection (red) - Double check your WiFi network

name (SSID).

If all of the above are set correctly, try sending the BlinkUp one more time.

We’ve found that it helps to close out all other app, or even try resetting

your phone if it continues to fail.

More troubleshooting information can be found on Electric Imp’s site.

Example 0: Hello World

Now that your imp is commissioned, it’s time to upload your first bit of code!

As with any new development platform, our first goal is to make sure we

can make an LED blink. If you can make an LED blink, you’re well on your

way to spinning motors or communicating with sensors.
