Datasheet

2. The board attempts to connect to the configured AP. LD2 blinks in blue for every 500 ms during this

process.

3. When the board successfully connects to AP and gets the IP address, the LED blinks in blue for

every 100 ms. The board attempts to connect to the AWS Cloud after successfully connecting to

AP.

4. On successful connection with the cloud, LD2 glows continuously instead of blinking.

5. The board reads the sensor value and LED data, and updates to the cloud with a publish message

to AWS IoT shadow for every two seconds.

6. The user can use a mobile application or speak to an Alexa-enabled device (for example, an Echo

Dot) to check the sensor values and LED color. The user can also turn on/off the LED and change

the LED color by speaking to the Alexa-enabled device or controlling the mobile application.

These details are depicted in the following functional flow.

The LD2 LED shows the operation of the board. When the board connects to the AWS cloud, LD2 turns

on and the color can be changed using the mobile application or Alexa-enabled devices (for example, an

Echo Dot). The following table shows the LD2 indication before successfully connecting to the AWS

Cloud.
