ESP8266 Community Forum

Around Two Years ago I used an ESP8266EX to control a light switch. It worked great, and all was good.
Last week a friend ask me to help set up a garage door opener and I had some more ESP8266EX’s so I started to work.
The ESP8266EX I am using is a Manufacturer: e0 Device: 4014
The FTDI is a 1232.
The IDE is Arduino 1.8.5
The ESP lib is esp8266 Community 2.4.1
The ESP Lib Selected is “Generic ESP8266 Module”
The test script is:
void setup() {
pinMode(0, OUTPUT);
}
void loop() {
digitalWrite(0, HIGH);
delay(500);
digitalWrite(0, LOW);
delay(500);
}

Everything looks good. I can load the script. It reaches 100% then the red light goes very dim and that is it. Nothing…
I reboot, 50% of the time the red light is bright, and sometimes I can get some console logging that has this:
Ets Jan 8 2013, rst cause :4 Boot mode:(3,7)
Wdt reset
Load 0x4010f000, len 1384, room 16

Chksum 0x2d
Csum 0x2d

Any Hint as to what I am doing wrong?

then the red light goes very dim and that is it.

How do you know that your power supply is not the cause?

The Power is from the FTDI. I tried Two ftdi1232 and two different PC's

It has been my experience that the FTDI does not have enough + 3.3 volt power to operate the esp8266 especially if it is being supplied by the 232 chip.
