Issue when to authorize the application

[jjwang]

Thanks for your reply! Then when I want to authorize the application according to the following steps:

1. Run alexa or /etc/init.d/alexa start to start Alexa Voice Service
2. 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 # or login in.

Alexa prompts:

Why does set_color() report error?

Maybe the usb device is used by other device. Try /etc/init.d/mopidy disable && /etc/init.d/mopidy stop.
You can run alexa without the mic array.
