Let’s make that LED blink green! Time to send a BlinkUp.

BlinkUp

To get your imp connected to your WiFi network as well as the online imp

servers, you need to go through the process Electric Imp calls

commissioning. There’s a great write-up on the commissioning process

over on Electric Imp’s Getting Started page. Here’s the gist of it, as well as

a few tips.

Before you begin, you’ll need to make an Electric Imp account by visiting

the IDE page.

Updating the imp with your WiFi credentials is a unique process. The imp

card has a built-in light sensor, looking out of the little window on the short,

flat edge of the imp. The imp002 has an external light sensor built into the

breakout board. The light-sensor can be used to process small amounts of

precisely modulated data in the form of a blinking light.

The light sensor is just behind the translucent window on the edge of the

imp card.

The light sensor on the imp002 is located to the left of the module, with the

lable “BU” (for BlinkUp).

To generate this blinking light, you need the Electric Imp app installed on

your smartphone (iOS or android). Go download that app if you haven’t

already!

Follow the directions in the app, and prepare to update the imp with your

WiFi network. Then, when your settings all look correct, hit the Send

BlinkUp button. Quickly place the screen of the phone as close to the imp’s

light sensor as possible.
