I was able to flash my ESP8266-01 with nodemcu firmware so atleast I know my chip is working. I have been trying to get some AT command answer from my ESP8266 but whatever I do it is not responding.
I have uploaded this program to arduino:
Arduino ESP
RX - TX
TX - VOLTAGE REGULATOR - RX
When I ground my ESP8266 reset pin , I get some crazy stuff at serial monitor:
I have uploaded this program to arduino:
Arduino ESP
RX - TX
TX - VOLTAGE REGULATOR - RX
C:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(2,3);
// When a command is entered in to the serial monitor on the computer
// the Arduino will relay it to the ESP8266
int LEDPIN = 13;
void setup()
{
pinMode(LEDPIN, OUTPUT);
Serial.begin(9600); // communication with the host computer
//while (!Serial) { ; }
// Start the software serial for communication with the ESP8266
mySerial.begin(115200);
Serial.println("");
Serial.println("Remember to to set Both NL & CR in the serial monitor.");
Serial.println("Ready");
Serial.println("");
}
void loop()
{
// listen for communication from the ESP8266 and then write it to the serial monitor
if ( mySerial.available() ) { Serial.write( mySerial.read() ); }
// listen for user input and send it to the ESP8266
if ( Serial.available() ) { mySerial.write( Serial.read() ); }
}
