Dear forum
I am trying to make a remote controlled car, using Bluetoothserial, and the App “Bluetooth electronics” from keuwlsoft. A lot of the program is running ok but the part with Serial.parseInt, wont work it is returning 0.
This is the original part from keuwlsoft, LED brightness

 //Process any info coming from the bluetooth serial link
  if (Serial.available()){
    BluetoothData=Serial.read(); //Get next character from bluetooth
    if(BluetoothData=='R') Red_value=Serial.parseInt(); //Read Red value
    if(BluetoothData=='G') Green_value=Serial.parseInt(); //Read Green Value
    if(BluetoothData=='B') Blue_value=Serial.parseInt(); //Read Blue Value
  }

in the program above this string is send from the mobile  R number(0..255) A
R are used to select. the number is used to set the brightness, as i see A is ignored 
As the program should be used on a arduino uno the number is used in analogWrite(pin,number).

when i converted the program to ESP32 i used — ledcWrite(led1, x);
I cant see what i am doing wrong, any one can help?

// Program with bluetooth control of a car
// ********************************************************************************
// Modified from SerialToSerialBT in the ESP-32 example packet
// builded on the example in the  ESP-32 serial bluetooth and led brightness
// from Keuw.com
// Modified by Steen.
// Dato 25/1 2022
// ********************************************************************************
// here data is read from ESP32 via bluetooth
// The unit communicating is a mobile phone and the app Bluetooth electronics
// the program can read two analog values A-værdi-A og B-værdi-B
// There are tre different binary values Cc Dd og Ee
