Использование SoftwareSerial.h в файле .cpp

Я пытаюсь объединить различные компоненты в моей сборке Arduino с помощью объектов, но у меня возникли проблемы с тем, который управляет беспроводным приемопередатчиком, который использует SoftwareSerial.h

Я считаю, что (в целом) правильно настраиваю использование этих объектов, потому что у меня есть другие объекты, которые правильно строятся в других файлах.

Я думаю, что моя проблема каким-то образом связана с SoftwareSerial.h, но у меня недостаточно знаний, чтобы войти и диагностировать ее... Я думаю, что моя основная проблема заключается в том, что SoftwareSerial не вводится должным образом.

Transciever.cpp

/*
   Этот код управляет трансивером HC-12.
*/
#include <Arduino.h>
#include <SoftwareSerial.h>

enum class TransReadStatus {
  RELAY_OFF,
  RELAY_ON,
  NO_DATA
};

class TranscieverHandler {
  public:
    TranscieverHandler(
      int txPinIn,
      int rxPinIn,
      int setPinIn,
      int baudRateIn
    ): txPin(txPinIn),
      rxPin(rxPinIn),
      setPin(setPinIn),
      baudRate(baudRateIn)
    {
      SoftwareSerial hc12(txPin, rxPin);
    }

    void init() {
      hc12.begin(baudRate);
      pinMode(setPin, OUTPUT);
      digitalWrite(setPin, HIGH);  // HC-12 нормальный, прозрачный режим
    }


    TransReadStatus checkForSignal() {
      while (hc12.available()) {             // Если у HC-12 есть данные
        incomingByte = hc12.read();          // Сохраняем каждый входящий байт из HC-12
        readBuffer += char(incomingByte);    // Добавляем каждый байт в строковую переменную ReadBuffer
      }
      delay(100);

      if (onBytes.equals(readBuffer)) {
        readBuffer = "";
        return TransReadStatus::RELAY_ON;
      } else if (offBytes.equals(readBuffer)) {
        readBuffer = "";
        return TransReadStatus::RELAY_OFF;
      }
      readBuffer = "";
      return TransReadStatus::NO_DATA;
    }

    TransReadStatus getLastRecievedStatus() {
      TransReadStatus newStatus = checkForSignal();

      if (newStatus == TransReadStatus::NO_DATA) {
        return lastStatus;
      }
      lastStatus = newStatus;
      return lastStatus;
    }

  protected:
    const int txPin;// = 10;
    const int rxPin;// = 11;
    const int setPin;// = 12;
    const int baudRate;// 9600

    const String setOffBytes = String("SET RELAY OFF");

    SoftwareSerial hc12;

    String readBuffer = "";
    TransReadStatus lastStatus = TransReadStatus::NO_DATA;
    unsigned long lastSendOnSignal = millis();

@Juraj Я подумал, что делаю что-то просто неправильно. Если вы сделаете это ответом, я отмечу его как принятый, @Snappawapa

Инициализация члена предназначена для построения объектов. Для целых чисел вы можете выполнить присваивание в теле конструктора 

TranscieverHandler(int txPinIn, int rxPinIn, int setPinIn, int baudRateIn)
    : hc12(txPin, rxPin) {
  txPin = txPinIn;
  rxPin = rxPinIn;
  setPin = setPinIn;
  baudRate = baudRateIn;
}
,

Полезно знать, прошло много времени с тех пор, как я в последний раз касался реального кода C++., @Snappawapa
