Alexa will be installed at the lasest firmware of ReSpeaker. If the command alexa is available, skip step 1.

    cd /tmp
wget https://github.com/respeaker/get_started_with_respeaker/raw/master/files/alexa_2017-01-18_ramips_24kec.ipk
opkg install alexa_2017-01-18_ramips_24kec.ipk

  2. Run alexa or /etc/init.d/alexa start to start Alexa Voice Service

  3. At the first time, you need to authorize the application.

    Connect ReSpeaker's Access Point, go to http://192.168.100.1:3000 and tt will redirect you to Amazon to sign up or login in.

  4. Run alexa to interact with Alexa.

Note: if you get error IOError: [Errno -9998] Invalid number of channels, It's likely that mopidy-hallo or alexa is running and using the audio input channel. You can stop mopidy by running /etc/init.d/mopidy stop. /etc/init.d/mopidy disable will disable it to auto-run. /etc/init.d/alexa start will run alexa on background.

On Ubuntu
