Step 5: Register Your ACK Module with Alexa and ACK services

In this step, you register your Alexa Connect Kit (ACK) module with Alexa by scanning the barcode that you generated in a previous step. This registers the ACK module with ACK managed services so the module can connect to Alexa.


Meet the following prerequisites, before you complete the instructions on this page.

  • Your ACK module isn't already registered to a user. If your module needs to be deregistered, see factory reset the module.
  • You downloaded the Alexa app. For installation instructions, see Download the Amazon Alexa App
  • Your Alexa app is running the minimum required version – 2.2.314100.0 (Android) or 2.2.315327.0 (iOS).

Restart the ACK development board

When the ACK module on the development board first receives power, it starts a beaconing process to make the device discoverable for barcode registration. After five minutes, the module returns to an idle state, and the module is no longer discoverable until it returns to an active beaconing state.

To restart the beaconing process, manually disconnect the USB cable from the Arduino Programming Port, and then plug it back in.

Register your device

To register your device

  1. On your mobile device, open the Alexa app.

  2. Select the Devices, and then select the plus sign (+).
  3. Select Add Device.
  4. From the list, select Development Device.

    Don't have a barcode
  5. For What brand is your development device, select ACK, and then click next.

  6. If prompted, enable access to Bluetooth, camera, and location services on your mobile device and then select next.
  7. To register the development device with Alexa, use the Alexa app to scan the barcode you generated in a previous step (the DVC_XXXXXXXXXXXXXXXX.png file). The default ACK test device is named Development Device.
  8. Select the Wi-Fi network to connect to, and if necessary enter the Wi-Fi password.
  9. After the ACK setup utility connects your module, you should see a notification that tells you that development device is set up and ready to use.
  10. You should see the status LED on your development board change from white to green. Your device is now connected to the Alexa service.

    If you run into issues, see troubleshoot the development kit.

  11. Verify that your test product appears on the Modules page of the ACK developer console.
