First

• For the first time, change the macro definition in board_def.h according to the corresponding layout and screen, and change the version to be used to 1.

  #define LORA_V1_0_OLED  0
  #define LORA_V1_2_OLED  0
  #define LORA_V1_6_OLED  0
  #define LORA_V2_0_OLED  1
  

• Set the corresponding macro definition according to the lora frequency of the actual module

  #define LORA_PERIOD 433  
  // #define LORA_PERIOD 868  
  // #define LORA_PERIOD 915     
  

• Sender definition LORA_SENDER is 1, 0 is receiving

Install the following dependency library files:

• arduino-LoRa
• oled-ssd1306
