Hello everyone, I´m new and I never have publish a topic in this forum so excuse me if this isn´t the right place to put my problem.

I´m using the IDE for programming my heltec wifi LoRa esp32 had been working correctly but this morning I can´t upload any Sketch.

I tried to upload Blink but don't works. I have this error.

esptool.py v2.6
Serial port COM5

My blink

Code: Select all

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

The Heltec wifi lora esp32 still working with the last upload sketch.

I´m using the same cable to connect the PC and Heltec esp32. Also I don't have connect some else in the board.
And I my PC detect the COM5 as the 'silicon labs CP210x controller' of my board.
I would appreciate you help and excuse my english.
