This application embeds aTelegram chatbot into the DISCO_L475VG_IOT01 board.
The Bot answers to the users queries about:

- Camera images taken from the Arducam-mini-2mp (optional).
This software uses:
- A modified version of the wifi library provided by ST in order to enable the TCP-SSL connection.
- An open source json parser jsmn (https://github.com/zserge/jsmn).
- A web service (http://now.http.org) to initialize the RTC.
- A web service (https://image-charts.com) to publish temperature,humidity and pressure charts.
- A modified version of the Arducam driver (https://os.mbed.com/users/dflet/)
