  LoRa Simple Client for Arduino :
  Support Devices: LoRa Shield + Arduino 
  
  Example sketch showing how to create a simple messageing client, 
  with the RH_RF95 class. RH_RF95 class does not provide for addressing or
  reliability, so you should only use RH_RF95 if you do not need the higher
  level messaging abilities.

  It is designed to work with the other example LoRa Simple Server

  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
