Dear Admin,
Thank You for your reply.
Whats is your ESP32 board model exactly?
Sincerely,

[Koray Tuncer]

I think it is not the right solution, but i disabled some codes with //

[code]
void setup() {

Serial.begin(115200);
//slowDownCpu();
pinMode(ONBOARD_LED_PIN, OUTPUT);

dht.setup(DHT_PIN, DHT_TYPE);
setUpWifi();
}

//void slowDownCpu() {
//rtc_clk_cpu_freq_set(RTC_CPU_FREQ_160M);
//uart_tx_wait_idle(0);
//int clockspeed = rtc_clk_cpu_freq_get();

//char* clockSpeeds[5] = {“XTAL”, “80Mhz”, “160Mhz”, “240Mhz”, “2Mhz”};
//Serial.print(“Setting CPU freq to: “);
//Serial.println(clockSpeeds[clockspeed]);
//Serial.println(“”);
//}
[/code]

It worked.
Does anyone know the right solution?

Yes same problem:
Board ESP-Wroom-32
I try the sketch temparature sensor only.

rtc_clk_cpu_freq_set’ was not declared in this scope

Need an urgent solution if possible.
