Update.
I have simplified my code and software in an attempt to locate a cause.
Here is my current circuit (A jumper is soldered from the RST pin to GPIO 16 on the chip).
The code is now much easier to read as well.
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
const int sleepDuration = 1; //Deep Sleep Duration in minutes
void setup() {
Serial.begin(115200);
Serial.println("\n \n Serial Test"); //Test Serial Output
Serial.println("sleeping");
delay(15000);
ESP.deepSleep(sleepDuration*6000000,WAKE_RF_DEFAULT);//Enter deep sleep, code executes from beginning on reboot
delay(15000);
}
void loop() {
}
Serial Output - With a reboot after flashing with Arduino IDE
At 115200 baud
At 74880 baud
After the allotted time is up the blue LED blinks once and turns off.
The last line of question marks at 74880 baud appears when it should wake up.
All voltages read as previously
Any more suggestions or tips?
This problem has been recreated with two esp8266-1 modules. I might end up with a nodeMCU.
