What are the differences among Smart Configuration, Sound Configuration, and AP Configuration?

There are different methods of adding device for the first time. Setting up the device using the smart configuration or sound configuration mode, the status indicator lights will alternate between red/blue – indicating that the device is in configuration mode. Setting up the device using the AP configuration, the status indicator lights will continuously flash blue. You will also receive voice prompts in some models. Most new devices or devices with updated firmware versions support AP configuration mode.
