3. Release the reset button, the ESP will boot in program mode.
4. Release the program button.

How to get ESP8266 to respond to commands?

This ensured that the ESP received correct commands. We ensured that each command we send is terminated by a CR for e.g. ESP8266.println (espCmd + “”); // where ESP8266 is SoftwareSerial ESP8266 (rxPin, txPin); Also, powering the ESP module with 5V gave no responses from ESP.

Do you need firmware to flash esp8266-01?

You need to have flashed the ESP with the AT command firmware. I was able to flash my ESP8266-01 with nodemcu firmware so atleast I know my chip is working. Click to expand… You may have flashed the firmware to use LUA programming.

Why is my at command not working on my ESP-01?

It does not sound to me like you have flashed the AT command set on your ESP-01. You may have had it on there initially, but you don’t have it now. So, you need to flash the AT command set. You can always flash it with something else afterwards (that is what you might have done with the nodemcu firmware).

Is the ESP8266 compatible with the Arduino stack?

The ESP8266 isnt really 5V friendly. Too Bad the Arduino outputs 5V on all of it Pins. You could still try it With a Voltage Divider using 2 Resistors or a level Shifter in hope it works. Elsewise With a 3.3V USB-> UART Module or get a New ESP8266
