IOTAppStory.com was started by Andreas Spiess and Onno Dirkzwager as a service for hosting firmware (apps) and for uploading these apps over the air (ota).
The general idea is that you have projects containing one of more devices which you want to update over the air. In the following pages we will go into more detail how users can accomplish this.
Currently we have based our service on the ESP8266 core for Arduino & Arduino core for the ESP32 .
Which means you can use nearly all the ESP8266 & ESP32 based devices currently on the market that have at least 1024 kB of flash memory. (4096 kB is preferred) And use the Arduino programming language (based on Wiring).
As time goes by we will support more platforms and programming languages.
