I am using Cactus Micro Rev2 and I'm trying to communicate with ESP via Mega32U4. I guess I have to update to espduino to be able to program the ESP side.

And I don't know current ESP firmware version. I tried firmware update (https://github.com/AprilBrother/espduino/tree/master/esp8266/release) via esptool but it gave connection error. And I can't erase flash it still gives an error. This time I tried via nodeMcu flasher:

It succeeds. But when I uploaded the basic serial communicate sketch to ESP and Mega32U4 side, I still don't get a response.

ESP side sketch:

{
Serial1.begin(115200);
}
void loop()
{
Serial1.println("Hello amk");
delay(1000);
}

MEGA32U4 side sketch:

String character = Serial1.readString();
Serial.println(character);
}

Believe me, I don't know exactly where I went wrong. I wrote more descriptive, but I was asked to ask one question. In short, how exactly can I update to espduino via NodeMCU flasher?

I'm trying to communicate with ESP via Mega32U4. I successfully upload .bin file with NodeMCU flasher but it doesn't give any respond. I can't even communicate simple serial. ESP side sketch file:

const char* ssid = "ADIisim"; 
const char* password = "biseylerbiseyler123";
void setup() {
Serial1.begin(115200);
}
void loop(){
Serial1.println("Hello amk");
delay(1000);
}

Settings (I'm not sure this settings, maybe wrong is here): enter image description here

I extracting .bin file with Arduino IDE and send to flasher with this settings:

Baudrate: 115200
Flash size: 512kB
Flash speed: 40Mhz
SPI Mode: DIO

Mega32U4 side sketch file:

while(Serial1.available()) {
String character = Serial1.readString();
Serial.println(character);}

Serial port didn't give any value. And I don't know ESP firmware version. I tried firmware update (https://github.com/AprilBrother/espduino/tree/master/esp8266/release ) via esptool but it gave connection error. And I can't erase flash it still gives an error. This time I tried via nodeMcu flasher:
