Introduction

Alexa is Amazon's personal virtual assistant which listens to user's voice commands and responds with appropriate answers. Apart from conversing with the user, Alexa lets you play music from a variety of music streaming services. Alexa also helps you manage to-do lists and allows for voice-assisted shopping from Amazon.

Device Configuration

  • Before proceeding with device configuration, make sure you have read and followed the Getting Started Guide. This will let you download and build the firmware, and then flash it on the board. Connect the board to your development host and power it on.
  • By default, when the firmware comes up it is un-provisioned. The device console should display the following lines in this mode:
I (xxx) conn_mgr_prov: Provisioning started with :
	service name = ESP-Alexa-xxxx
	service key =
	proof of possession (pop): abcd1234

You can use either of the Android or iOS apps (links below) to provision your device to the desired Wi-Fi Access Point and associate the user's Amazon account with the device.

Demo

  • Once the board boots up and successfully connects to the Wi-Fi network after provisioning, you will see a print "Alexa is ready", after which you can use either use "Rec" button on the board or say "Alexa" to start a conversation. For Tap-to-Talk, press and release the button and speak. The green LED glows when the microphone is active.
  • You can connect any external speaker/headphone with 3.5mm connector to PHONE JACK to listen to responses.
  • you can now ask any command like:
    • Tell me a joke
    • How is the weather?
    • Will it rain today?
    • Sing a song
    • Play TuneIn radio
    • Set volume to 7
  • Press and Hold "Volume+" and "Volume-" button for 10 seconds to reset the board to factory settings.
  • Press and Hold "Action" button for 5 seconds to just reset the wifi settings.
