I have a sketch and want to pull a GPIO high to CH_PD after using a manual switch from VCC to CH_PD. It is taking about 13 seconds of holding the switch closed to get the GPIO switched high. It is the first thing in my setup. I also turn on the blue LED on the ESP-12F module to get a visual confirmation on the timing. Is this normal? Is there any way I can speed this up?

Hi, about 325mS, so for some reason your setup is taking a long time. Have a look at this post - most of the bits you need are on the first two pages.

Are you certain your reset pin is high? I think there is something else going on. It should get to setup fairly quickly.

If it's 500ms max to get to setup() then that would be fine. So something is wrong, but I am not sure what. Toggling GPIO#13 is the first step in my program:

Code: Select all

const int TOGGLE_CH_PD = 13;

void setup() {
pinMode(TOGGLE_CH_PD, OUTPUT);
digitalWrite(TOGGLE_CH_PD, HIGH);
...

I am using these libraries:

Code: Select all

#include <NTPClient.h>
#include <ESP8266WiFi.h>
#include <WiFiUdp.h>
#include <ESP8266mDNS.h>
#include <DNSServer.h>
#include <WiFiClient.h>
#include <EEPROM.h>
#include <ESP8266WebServer.h>
#include <TimeLib.h>
#include <ArduinoOTA.h>
#include <FS.h>

I am basically following this example (circuit), but with an ESP-12F module. I also see other people mention in the comments that it takes 6 seconds of holding the button.

I connected reset to VCC with a 1K resistor.
