Here is the Blink Sketch i flashed to the esp8266.
It’s not blynk sketch but is edp8266 Blink Sketch.
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN ,LOW);
delay(1000);
digitalWrite(LED_BUILTIN, HIGH);
delay(2000);
}
The blue LED is connected to TX of the ESP, so it is absolutely normal it flashes during programming. The question is, how it behaves when you do NOTHING on serial lines… endless flashing indicates bootloop --> something is wrong. The fotos you have posted are showing wrong baudrate, but the initial of the ESP AT firmware is (I think) 115200.
The default 74880 is used by ESP for debugging and is valid ONLY during boot phase (unless programmed so - but who would?)
I think it would be best to abandon AT firmware (at least for some time - best forever) and do what is suggested by @Costas and @PeteKnight. Flash whatever example (for ESP standalone) leave debug enabled, and you should see serial output at baudrate programmed in setup() function
I want the esp8266 work as host and connect to my arduino uno which don’t have wireless function. So i can using wifi to control the arduino uno.
I flash the esp8266 standalone how to connect the pins to arduino uno?
It’s difficult to provide help and guidance if you’re not clear about what you’re trying to achieve!

OK, I’m out of here.
It won’t work… Or… it is not meant to work that way…
Just try that:
Set console to 9600…
void setup() {
Serial.begin(9600);
Serial.println("Hello, I'm here");
}
void loop() {
Serial.println("I'm still here!");
delay(1000);
}
I’m a newbie, pls advise and help when u r free.
We get that, and that’s why we’re trying to help, but it’s difficult when you’re not clear about what you’re trying to achieve and what steps you’ve taken.
Did you read the thread about issues with the programmer you’re using and how to fix them?
It would help if you put more relevant information into each post, rather than a series of one line answers to different questions/comments.

Default AT Firmware : http://wiki.ai-thinker.com/esp8266/sdk
Halo guys,
My esp8266 module now can respond to the AT command since i flashed the default AT firmware which provided by the AI manufactoring website. Above is the link for the default firmware and the photo is the link for download default firmware.
Good, glad you have it working.
You can mark the topic as “Solved” if you don’t need any gurther help on this subject.

How to mark “Solved”?
How to mark “Solved”??
I would like to know
what’s “ESP Flash Download Tool (Software)” you use to flash to your ESP ?
Thank you Sir.
SIR, Someone plz help… im facing the same problem and tried with all above solutions but no use. im also the new to coding. I wanted make a communication from arduino to esp8266 using AT Commands…but despite of many AT And other Firmware updates, its not responding. tried above all solutions.
You’re probably using the wrong baud rate to talk to the ESP-01.
Do you have an FTDI adaptor or an ESP-01 to USB interface available?
Pete.
sir, actually im using nodemcu development board having FTDI on it. so direct usb connection to nodemcu. baud rate - i tried with 9600,74800,115200… as I told, i tried with all the solutions that you told someone previously above. plz help
So the rest of this topic was about a problem with an ESP-01 as a Wi-Fi modem for a an Arduino and you’ve said that you are
but in fact you’re using different hardware.
You say that you’ve done
I’d doubt very much if any of that has helped. If you’ve installed anything other than the correct AT firmware for your board (which will be different to the AT firmware for an ESP-01) then you’ll not get this working.
There’s a thread about someone else who has truied thys, and finally managed to get it to work, just here:
I’m locking this thread, as your issue is unrelated. If you need further assistance the please start a new thread with full details about your hardware, firmware, code, results etc but bear in mind that this isn’t really a Blynk issue until you get your Arduino talking to your NodeMCU.
Pete.
