How can a member of class of type BufferedSerial be initialized?

Hello,

I am trying to move some pieces of my code to a class named MyClass where I have a private member BufferedSerial _mySerial. Unfortunately, I got a lot of compiler's errors that I don't know how to resolve. I will appreciate any help that anyone can provide.

MyClass.h

#include "mbed.h"
#include "BufferedSerial.h"

class MyClass {
public:
    // define which pins are used
    MyClass(PinName tx, PinName rx);

private:
    BufferedSerial _MySerial;

    void _RxCallback();
};

MyClass.cpp

#include "MyClass.h"

MyClass::MyClass(PinName tx, PinName rx) : _MySerial(tx, rx, 512) {
    _MySerial.baud(230400);
    _MySerial.attach(callback(this, &MyClass::_RxCallback), Serial::RxIrq);
}

I have answered my own question :)

MyClass.h

#include "mbed.h"
#include "BufferedSerial.h"
 
class MyClass {
public:
    // define which pins are used
    MyClass(PinName tx, PinName rx);
 
private:
    BufferedSerial *_MySerial;
 
    void _RxCallback();
};

MyClass.cpp

#include "MyClass.h"
 
MyClass::MyClass(PinName tx, PinName rx)  {
    _MySerial = new BufferedSerial(tx, rx);
    _MySerial->baud(230400);
    _MySerial->attach(callback(this, &MyClass::_RxCallback), Serial::RxIrq);
}

Many thanks! that way I fixed MQTTmbed.h
