Hello there,
Wanting to use ESP-03 to add wifi to arduino project and was working well during testing but after I issued the AT+RST command, I no longer receive responses from the ESP8266.
I'm using a breadboard PSU to supply 3.3V VCC, logic level converter forTX/RX and have CH-PD tied to VCC and GPIO15 tied to ground.
I originally had changed ESP8266 baud to 9600 as 115200 wasn't stable with SoftwareSerial.
But it doesn't respond with either 9600 or 115200 now.
Am i missing something or have i just probably burnt the board somehow?
Just using this code to test.
Appreciate any tips or info I may have missed.

Code: Select all
#include <SoftwareSerial.h>
SoftwareSerial ESPSerial(2, 4);
void setup() {
Serial.begin(9600);
ESPSerial.begin(115200);
//ESPSerial.begin(9600);
}
void loop() {
if (Serial.available()) {
String str = Serial.readStringUntil('\n');
Serial.println("");
Serial.println("You sent: " + str);
ESPSerial.println(str);
}
if (ESPSerial.available()) {
char chr = ESPSerial.read();
if(chr != 0) Serial.print(chr);
}
}Appreciate any tips or info I may have missed.
