...

Code Block
1. Initialize and download the code base
 - Example for RaspberryPi:
 (we can use rdkv.xml to build with external source method or rdkv-nosrc.xml to build without externalsrc)
 $ repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-nosrc.xml -b rdk-next
 $ repo sync

2. Download the meta-rdk-voice layer in project root
 $ git clone https://code.rdkcentral.com/r/rdk/components/generic/rdk-oe/meta-rdk-voice

3. Enable the below DISTRO feature to build AVS plugin
 $ vi meta-rdk-voice/conf/layer.conf
 - enable the below commented line
 #DISTRO_FEATURES_append = " alexa-plugin"

4. For the external source builds (such as some Broadcom platforms) add below line in manifest/auto.conf
 - In <Manifest>.xml
   <project name="components/generic/avs/alexa_skill_mapper" revision="rdk-next"/>
 - In auto.conf (where brcmexternalsrc is enabled)
   BRCMEXTERNALSRC_pn-wpe-alexaskillmapper += "rdk/components/generic/avs/alexa_skill_mapper"
   SRCPV_pn-wpe-alexaskillmapper = "${BRCMEXTERNAL-SRCPV-CMF}"
 $ repo sync

...

Code Block
4. if wanted to use MIC based implementation (Ignore if using BLE voice remote)
 $ vi meta-rdk-voice/conf/layer.conf
 - enable the below commented line
 #DISTRO_FEATURES_append = " alexa_ffv"

...

Keyword detector (KWD) support enables the device to wake-up & listen to input after receiving the hot word  "Alexa". It is used with devices that has on-board Microphone-board Microphone

This option need to be enabled along with "alexa_ffv" DISTRO for MIC based voice input

Code Block
1. To use pryon lite KWD engine for devices with MIC input
 Note: Source code need to be obtained from amazon separately
2. Set the KWD support flag to "ON"
  $ vi meta-rdk-voice/recipes-wpe/wpeframework/include/avs.inc
    AVS_KWD_SUPPORT ?= "ON"
3. include the KWD detector recipe to build.
 - enable the commented line 
 #PREFERRED_PROVIDER_virtual/alexa-kwd-detector = "pryonlite"
4. Create a bbappend file in platform layer and provide artifact location
e.g. 
 $ vi meta-rdk-oem-<OEMNAME>/meta-<MACHINE>/recipes-avs/pryonlite/pryonlite_2.3.0.bbappend
   SRC_URI  = "file://pryon_lite_2.3.0-metrological-2019.12.23.2344.zip"

...

  1.  Go to the controller web UI by typing http://<Device-IP> in a browser
  2. Select the controller option from left pane menu
  3. toggle the AVS option to activate the plugin

For systemd service (old implementation)

  1. Login to the device with "ssh root@<Device-IP>
  2. start the alexa service by invoking "systemctl start alexa.service"

Customization

Mapping to amazon developer account

...

Code Block
1. Login to the device
 $ ssh root@<RDKV-Client-IP>

2. Edit the Configuration file
 $ cd /usr/share/WPEFramework/AVS
 $ vi AlexaClientSDKConfig.json
     "deviceInfo":{
        // Unique device serial number. e.g. 123456
        "deviceSerialNumber":"<SERIAL_NO>",
        // The Client ID of the Product from developer.amazon.com
        "clientId":"<CLIENT_ID>",
        // Product ID from developer.amazon.com
        "productId":"<PRODUCT_ID>",
        // The name of the device manufacturer.
        "manufacturerName": "<MANUFACTURER_NAME>",
        // The description of the device which should contain the manufacturer name or how the device is connected.
        "description": "<DESCRIPTION<DESCRIPTION>"
    },

Front Panel LED Notifications

...

We can check the authorization code using below command:

  • In case of systemd implementation:

$ systemctl status alexa

  • In case of plugin implementation

$ tail -f /opt/logs/wpeframework.log
