i cant upload anything to the esp8266. does not respond
Posted: Sun Apr 11, 2021 4:43 ami recently got the esp8266 01s wifi module listed here https://www.sparkfun.com/products/17146
and i wanted to test it out, so i tried to upload the blink example program and im getting a unique problem (didnt find anything like it online).
here is my arduino nano to esp8266 connection
Arduino nano esp8266
3.3V VCC
GND GND
RX0 RX
TX1 TX
GND IO0 / GPIO0
3.3V EN
and i put a wire to connect arduino nano GND to RST
and i downloaded the esp8266 board and picked the generic esp8266 board
and from there i uploaded this modified blink program
i always get this error "esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header
"
i do not know why even though Arduino ide says this
but it then stops working altogether
esptool.py v2.8
Serial port COM10
Connecting........_____....._____....._____....._____....._____....._____.....____

Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(2, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(2, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(2, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
