Using wifi with phone app

Hi,

I am creating a mobile phone application using AppStudio https://www.nsbasic.com/app/.

To communicate with the applications, i plan to use a wifi device connected to an arduino.

AppStudio apps can talk with a couple of protocols including:

  1. As a web server: AppStudio sends http requests (AJAX) and gets replies from the Arduino.

  2. WebSockets

Is there any wireless device that supports any of the above protocols?

Greatly appreciate any guidance.

Thanks
