ESP-01S Not Responding on second launch
Posted: Tue Oct 09, 2018 5:00 pmHere's the code:
The ESP8266-01S wires are as follows:
GND to arduino ground
3v3 to arduino 3v3
RX to arduino pin 5
TX to arduino pin 6
EN to arduino 3v3
The thing worked for one time, and when I re-compiled and sent it again without any changes or even button presses, it stopped working. Furthermore, if I connect ESP module directly through arduino rx and tx and connect arduino reset to ground, I still don't get anything. The led on the esp is blinking during data transfers, but everything else doesn't change and I get no response at all.
Code: Select all
#include <SoftwareSerial.h>
#define RX 6
#define TX 5
String AP = "...";
String PASS = "...";
SoftwareSerial esp8266(RX,TX);
void setup() {
Serial.begin(9600);
Serial.println("Setup started");
esp8266.begin(115200); // Change this to the factory baudrate used by ESP8266
delay(1000);
Serial.println("Setting BAUDRATE to 9600");
esp8266.println("AT+IPR=9600");
esp8266.begin(9600);
delay(500);
Serial.println("Setup finished");
reset();
connectWifi();
}
//reset the esp8266 module
void reset() {
Serial.println("Resetting...");
esp8266.println("AT+RST");
delay(3000);
if (esp8266.find("OK"))
Serial.println("Module Reset");
else
Serial.println("Module Reset Failed!!!");
}
//connect to your wifi network
void connectWifi() {
Serial.println("Connecting to Wifi...");
String cmd = String("AT+CWJAP=\"") + AP + "\",\"" + PASS + "\"";
esp8266.println(cmd);
delay(4000);
Serial.println("Checking Wifi...");
int ctr=0;
while(!(esp8266.find("OK"))) {
if(esp8266.find("ERROR")) {
Serial.println("Cannot connect to wifi...");
break;
}

++ctr;
