- Mon May 08, 2017 3:50 am #65699 no, upgrading didn't do any thing.
i'm going to try running the blink example and slowly add my code one line at a time..
i've wasted 15 hours on this.

- Mon May 08, 2017 5:35 am #65702 yup, no change, the only thing i havn't changed is the ftdi serial to usb thingy. but it works and will upload code so it can't be that can it?!
i've just soldered on two new wires from tx and rx so they are an inch long.

So to recap:
simple code caused a WDT reboot, but very simple code (like blink) works fine.
I've tried:

replacing the module
soldering onto stripboard rather than breadboard and dupont
using a bigger power supply
removing the lm regulator and providing 3.3v directly
increasing to 3.4
unsoldering all other pins except those needed to flash and run
upgrading my version of ardunio
shortening the tx/rx leads
adding a 10uF capaciotr accross gnd and vcc of the module
adding a 1nF ceramic capacitor accross gnd and vcc
adding ANOTHER 1nf in parralel with the 1nF and 10uF capacitor
changing the board parameters in arduino before uploading (Currently ESPDUino (ESP-13 Module), 80 Mhz, 115200, 4M (3M SPIFFS))
using a different computer
worshipping Satan.
Swearing...a lot.

Current Code that does not work:

Code: Select all/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://www.arduino.cc

  This example code is in the public domain.

//ok lets declare them
int ServoSignal = 4;
int RelaySignal = 5;
int LEDClosed = 12;
int LEDOpen = 13;
int ButtonOpen = 14;
int ButtonAC = 16;

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(ServoSignal, OUTPUT);
  pinMode(RelaySignal, OUTPUT);
  pinMode(ButtonOpen, OUTPUT);
  Serial.begin(115200);
  Serial.println("i'm in the setup.");
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(ServoSignal, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(ServoSignal, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
  Serial.println("blink");
}

Earlier you said you had ESP-12E modules. I don't know if ESPDUino - ESP-13 Module is the same. If you have the ESP-12E I would stick with the Generic ESP8266 module selection.
