#when connecting to AWSIOT , a cert , privatekey and certificate authority file is required . 
#after downloading the cert files when creating a thing , it is possible rename the files so that it is easier to
#call the file when writing the script and cli 
#also note that aws things shadow update requires message to be in json to update 
#to catch messages sent to things but are rejected due to improper json format ,  subscribe to things shadow update through mqtt. 
# do remember to check the activity page for the AWsiot " thing" u have created to see whether the message is accepted or rejected

  This is a simple example show the LoRa sended data in OLED.

  The onboard OLED display is SSD1306 driver and I2C interface. In order to make the
  OLED correctly operation, you should output a high-low-high(1-0-1) signal by soft-
  ware to OLED's reset pin, the low-level signal at least 5ms.

  OLED pins to ESP32 GPIOs via this connecthin:
  OLED_SDA -- GPIO4
  OLED_SCL -- GPIO15
