I am using Adafruit feather huzzah esp8266 module for some nice project,
Among other things I need to get environment variables from a Windows PC and store them later in EEPROM (Like SSID and other stuff)

I can write easily to the debug monitor window, but have difficulties to read back data using Serial.readString/Serial.readStringUntil?

Can you please let me know what should I check/take care in order to read serial data?

Regards
Asaf

Code: Select all#include <ESP8266WiFi.h>


void setup() {

  String str;
 
  Serial.begin(115200);

  Serial.println("Hello"); 

  Serial.setTimeout(30000); // 30 Sec time out
   
  Serial.print(F("Enter SSID:"));
  str = Serial.readString();
  Serial.println(str);

  Serial.print(F("Setup End"));

}


void loop() {
 
    delay(5000);
}
