I am building an IoT device based on Android and I am trying to understand how I can use a smartphone to configure a device for connection to Wifi. The IoT device doesn't have a Screen. So I want to connect the device to Wifi through the Smartphone.
I can build Android Apps that can be pushed to the device as well as to the smartphone.
I want to do something like this - How to Set Up Your Ring Video Doorbell 1:25 Set Up WIFI Connection
How do devices like Security cameras connect to Internet by using a mobile phone?
