Hello,
Board info: Arduino Nano 33 IOT
I keep getting the user_interface error when compiling my code under the edgent 8266 sketch.
I have tried to create an header file with that name and still doesn’t work. I have tried a different company and still faced with the same issue.
My arduino IDE is 1.8.15
Blynk 1.01
I don’t know what I am doing wrong here please help.
The Nano 33 IOT isn’t an ESP8266 based board, so that’s probably the cause of the error message.
Pete.
Thank you Pete for your prompt reply as usual. Below is the error I am currently getting when I use ESP32.
#include <WiFiClientSecure.h>
^~~~~~~~~~~~~~~~~~~~
compilation terminated.The Nano 33 IOT isn’t an ESP32 either!
Pete.
Thank you John93. I am. Here is my screenshot. 
Can you show me your sketch ?
I am using the Blynk Edgent sketch. It has multiple header files. This is the Edgent_ESP32.ino. Let me know if you want the content of all the header files as well.
// Fill-in information from your Blynk Template here
#define BLYNK_TEMPLATE_ID ""
#define BLYNK_DEVICE_NAME ""
#define BLYNK_FIRMWARE_VERSION "0.1.0"
#define BLYNK_PRINT Serial
//#define BLYNK_DEBUG
#define APP_DEBUG
// Uncomment your board, or configure a custom board in Settings.h
//#define USE_WROVER_BOARD
//#define USE_TTGO_T7
#include "BlynkEdgent.h"
void setup()
{
Serial.begin(115200);
delay(100);
BlynkEdgent.begin();
}
void loop() {
BlynkEdgent.run();
}Okay.
First go to blynk / blynk.edgent and choose edgent_MKR1000 not edgent_ESP32
Second they will ask you to download some libraries ( if not already installed ) just download them and everything should work just fine.
It errored on header file BlynkEdgent.h.

Screenshot:
[image|690x270](upload://vEVe1QQbrL7auSkRkQcdtOLahYr.png)I’m sorry choose MKR_1010 not MKR1000
Got hit by another error:

#include <WiFiNINA.h>
^~~~~~~~~~~~
compilation terminated.
Download wifinina library, timer5 library and ArduinoOTA library.
I have successfully installed those libraries.
Now try to upload the sketch
After I ran it, the error went away and now, I am being confronted with another error:
#include <FlashStorage.h>
^~~~~~~~~~~~~~~~
compilation terminated.
FlashStorage.h: No such file or directoryYou can find it here :
I dont have EEPROM feature on my board, should I still proceed?
Yes
Wow! Wow! Wow! Thank you, Thank you so very much John93. You are AMAZING. I most deeply appreciate your patience and your guidance.
I am able to compile my code successfully and also able to see my board SSID when I scanned for it.
