In case it will be useful to the forum helpers, I'll mention that the code shown in @donglectu's screenshot is this part of the library code:

github.com/arduino-libraries/MKRWAN

src/MKRWAN.h

1.1.1


      
          #ifdef SerialLoRa
            // Sends the modem into dumb mode, so the Semtech chip can be controlled directly
            // The only way to exit this mode is through a begin()
            void dumb() {
          	SerialLoRa.end();
          	pinMode(LORA_IRQ_DUMB, OUTPUT);
          	digitalWrite(LORA_IRQ_DUMB, LOW);
          
          	// Hardware reset
          	pinMode(LORA_BOOT0, OUTPUT);
          	digitalWrite(LORA_BOOT0, LOW);
          	pinMode(LORA_RESET, OUTPUT);
          	digitalWrite(LORA_RESET, HIGH);
          	delay(200);
          	digitalWrite(LORA_RESET, LOW);
          	delay(200);
          	digitalWrite(LORA_RESET, HIGH);
          	delay(50);
          
          	// You can now use SPI1 and LORA_IRQ_DUMB as CS to interface with the chip

@donglectu please don't post pictures of text. That is very unhelpful. Post text as text!

how to set Pin mapping for mcci lmic :

const lmic_pinmap lmic_pins = {
.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = A0,
.dio = {2, 7, 8},
};
