After the small Chrome App experience that resulted in a very compact app that reads Video and sends an UDP binary stream to ESP32 Led controllers I decided to start learning how to program a real mobile app.
Real because I find that the way to do it must end in the App Store and the user should be able to install it with a few clicks.
This start guide is only valid for Linux but it could be a similar approach in Mac.

1.- Install Java 8 SDK

2.-Cordova
https://cordova.apache.org/#getstarted

It’s very straight-forward to start if you have previous html/javascript experience building a web page.

In this github repository:
https://github.com/martinberlin/udpx-app

I’m building my very first Android app. Follow the commits and watch the Repository to see my new steps and also my failures in this new world.

This is a preview of how the app looks like in it’s first version:

udpx Android application is available in the Play store.

Soon more posts will follow explaining how to interface with Android OS (Camera as an example). There will be soon more issues to expand and implement in this repository. And my new philosophy to build Firmware for Espressif chips will be simply:

“One firmware, one mobile application”

Meaning that every firmware will have his app, where you can configure and test it, just with one click install in google Play store and setting up some very easy configuration. Starting from WiFi credentials using BLE (Bluetooth low energy) and setting up the App IP address as a last step.

My goal at last, is that internet of the things is easy to use, and not something where you need a 20 minutes complicated setup to start using something. So the mission is that for first weeks 2020 all master branches from our main ESP32 Firmwares like udpx and Remora should be bluetooth configurable.
