The folders contain the Javascript required to build an Axway Titanium iOS application (which must include the ti.bluetooth iOS module) and also an Arduino sketch for an ESP32 micro-controller module and 64x32 OLED screen.
The Arduino sketch uses the latest ESP32 BLE Arduino library from https://github.com/nkolban/ESP32_BLE_Arduino.
The mobile application emulates a kind of joystick/gamepad and sends x,y values between -1.0 and 1.0 to the ESP32, which updates the x and y values on the screen.
This is just an example/test to learn how to use something like this to control some motors for a robot project or something similar.
