HC-05 bluetooth how to read RSSI

I am using HC-05 bluetooth module and I got RSSI values but they're in HEX. I want to somehow convert them to -dBm and later display it. Google says nothing. I'm using Arduino Mega 2560.

My code in Arduino

char c = ' ';
byte AtmodePin = 2;
 
void setup() 
{
    pinMode(AtmodePin, OUTPUT);
    digitalWrite(AtmodePin, LOW);
    
    Serial.begin(9600);
    Serial.println("Serial 0 ON");
 
    Serial1.begin(9600);  
    Serial.println("Serial 1 ON");
}
 
void loop()
{
    if (Serial1.available())
    {  
        c = Serial1.read();
        Serial.write(c);
    }
 
    if (Serial.available())
    {
        c =  Serial.read();

        if (c == '#')
        {
          digitalWrite(AtmodePin, HIGH);
          Serial.print("AT mode ON. $ zeby wyjsc");
        }

        else if (c == '

There is what HC-05 dumps, especially last digits in row (RSSI)

OK

        {
          digitalWrite(AtmodePin, LOW);
          Serial1.print("AT+RESET\n\r");
          Serial.print("AT+RESET\n\r");
        }

else
        {
        Serial.write(c);
        Serial1.write(c);

    }

Store the data in a string, instead of just printing (incorrectly) one character at a time.

Once you have stored the data in an array, until the end-of-record marker arrives, use strtok() to parse the string. Use strtoul() to convert the token to an unsigned long (or use strtol() to convert to a long).
