Integrating Alexa Video Skill Kit with RDK

Build instructions

Alexa related recipes are bundled inside meta-rdk-voice/recipes-avs and contains below build targets

...

The build instructions are mentioned by taking RaspberryPi as an example but should be almost similar for other platforms.

Build Instructions for AVS Plugin

1. Initialize and download the code base
 - Example for RaspberryPi:
 $ repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-nosrc.xml -b thunder-next
 $ repo sync

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

5. To use pryon lite KWD engine (source code need to be obtained from amazon separately)
 a. Set the KWD support flag to "ON" in meta-rdk-voice/recipes-wpe/wpeframework/include/avs.inc
 b. include the KWD detector recipe to build.
 - enable the commented line
#PREFERRED_PROVIDER_virtual/alexa-kwd-detector = "pryonlite"

 # Please follow the steps mentioned in section #3.2 to enable USB audio kernel parameters (Not required for RaspberryPI).

5. Optionally 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-alexa += "components/generic/avs/alexa_skill_mapper"
   SRCPV_pn-wpe-alexa = "${BRCMEXTERNAL-SRCPV-CMF}"
 $ repo sync
6 .Build the image target
 - Example for RaspberryPi
 $ source meta-cmf-raspberrypi/setup-environment
 ### select meta-cmf-raspberrypi/conf/machine/raspberrypi-rdk-hybrid-thunder.conf ###
 $ bitbake rdk-generic-hybrid-thunder-image

Code Block

1. Initialize and download the code base - Example for RaspberryPi: $ repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-nosrc.xml -b thunder-next $ repo sync 2. Download the meta-rdk-voice layer in project root $ git clone https://code.rdkcentral.com/r/components/generic/rdk-oe/meta-rdk-voice 3. Add to BBLAYERS $ vi meta-rdk/conf/bblayers.conf.sample BBLAYERS += "${@'${RDKROOT}/meta-rdk-voice' if os.path.isfile('${RDKROOT}/meta-rdk-voice/conf/layer.conf') else ''}" 4. Optionally 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" # Please follow the steps mentioned in section #3.2 to enable USB audio kernel parameters (Not required for RaspberryPI). 5.

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

We will be able to see a message similar to below format. Note the code that appears in console window, this will be required while authorizing with developer account.
