I watched this tutorial to figure out how to upload my sketch to the esp 01. I don’t have the usb device so I am using my arduino uno as a replacement to upload sketches to esp01.
It work the first time but couple last day when i try to use this method to for upload to the blynk cloud but it not working so i try back with arduino and now it keep showing this error. I’ve checked every detail like wired and code but it still can not upload the code.
Error file
cloud_upload_error.txt (3.5 KB)
My wired:
Code:
#include "thingProperties.h"
const int relayPin = 0;
void setup() {
  // Initialize serial and wait for port to open:
  Serial.begin(9600);
  // This delay gives the chance to wait for a Serial Monitor without blocking if none is found
  delay(1500); 
  pinMode(relayPin,OUTPUT);
  
  // Defined in thingProperties.h
  initProperties();
  // Connect to Arduino IoT Cloud
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
  
  setDebugMessageLevel(2);
  ArduinoCloud.printDebugInfo();
}
void loop() {
  ArduinoCloud.update();
  // Your code here 
  
  
}
void onRelaySwitchChange()  {
  // Add your code here to act upon RelaySwitch change
  if(relaySwitch){
    digitalWrite(relayPin,HIGH);
  }else{
    digitalWrite(relayPin,LOW);
  }
}
Thanks you much for your support.
