ESP32 Bridge to Control DeLonghi Coffee Machines.

Initially developed for a DeLonghi Dinamica plus.

Requires Arduino IDE with ESP32 board supported, added via preferences as an additional board URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Uses these libraries:

• https://github.com/plapointe6/EspMQTTClient v1.8.0
• https://pubsubclient.knolleary.net/ v2.8.0

Having BLE and MQTT inside the app makes it quite large, try one of the no-OTA flash schemes (such as a 2MB APP one).
