Dabble ESP32 Library Problem

[Rangorts]

I try to compile the example code. But it's not working. What is the problem?

Code:
#define CUSTOM_SETTINGS
#define INCLUDE_LEDCONTROL_MODULE
#include <DabbleESP32.h>
unsigned long lasttime=0;
void setup() {
Serial.begin(115200);
Dabble.begin("MyEsp32");
}

void loop() {
Dabble.processInput();
Serial.print("Led:");
Serial.print(LedControl.getpinNumber());
Serial.print('\t');
Serial.print("State:");
Serial.print(LedControl.getpinState());
Serial.print('\t');
Serial.print("Brightness:");
Serial.println(LedControl.readBrightness());
}

I have the same problem, for me the solution is to change the version of esp 32 library to 2.0.17
you can read the full solution here https://forum.arduino.cc/t/esp32-control-bldc/1266716/3

Same issue. This should only be a workaround. Im using platformio and don´t get STEMpedia running regarding missing declaration:
