No ESP8266 connection

#1

Hi

I have just received my new Cactus micro 2. But I am not able to connect to the ESP8266.

The code looks like:

String tmp; 

#define BAUD_RATE 9600

void setup() {
  Serial.begin(BAUD_RATE);
  Serial1.begin(BAUD_RATE); 

  Serial.println("Hello Cactus Micro!");

  // Enable esp8266 
  pinMode(13, OUTPUT);
  digitalWrite(13, HIGH); 
  delay(1000);//delay 
};

void loop() {


  //set mode needed for new boards
  Serial1.println("AT+RST");
  delay(3000);//delay after mode change
  Serial1.println("AT+CIPMUX=0");
  delay(300);
  Serial1.println("AT+CIPMODE=3");
  delay(300);
  Serial1.println("AT+RST");
  delay(500);
  Serial1.println("AT+CWMODE=1");
  delay(500);
  
  Serial1.println("AT+GMR");
  ShowSerialData();
  delay(500);
  
  Serial.println("Setup done");

}

void ShowSerialData() {
  //output everything from ESP8266 to the Arduino Micro Serial output
  while (Serial1.available() > 0)  {
    tmp += char(Serial1.read());
    delay(2);
  }
  
  if(tmp.length() > 0) {
    Serial.println(tmp);
    tmp = "";
  }

}

My monitor only keeps showing Setup done.

The setup is USB connection only.
Board lilipad arduino USB

I have tried different baudrates and still no results.

I have also tried hardwareSerialMonitor.ino without any luck.

Please help.
