ESP8266 Feather Huzzah doesn't work with IoT Cloud

Hello, I'm trying to use my ESP8266 board (feather huzzah) with the IoT Cloud platform. It worked during a day and the next day, nothing. I just tried without code (just the code automatically generated). I just have "0�~?�4��" on the serial monitor. Usually, I have this message and then the messages about internet connection. Today, I just have "0�~?�4��" without any error message. I don't understand...

Hi @ayubowan. Do you have the Serial Monitor baud rate menu set to match the value in the Serial.begin() call in your Thing sketch?

Hi, thank you for your answer.

Yes, the serial baud rate is correctly set. I delete the thing and the board and I add them again and the empty sketch is working. I think it is a bit buggy because esp8266 is not perfectly supported.

Now, I added a bit of code but the esp8266 keeps crashing.

Here is the code:

#include "thingProperties.h"

#include "GxEPD2_BW.h"
#include "GxEPD2_display_selection_new_style.h"

void setup() {
  // Initialize serial and wait for port to open:
  // This delay gives the chance to wait for a Serial Monitor without blocking if none is found

  // Defined in thingProperties.h

  // Connect to Arduino IoT Cloud
     The following function allows you to obtain more information
     related to the state of network and IoT Cloud connection and errors
     the higher number the more granular information you’ll get.
     The default is 0 (only errors).
     Maximum is 4
  // comment out next line to have no or minimal Adafruit_GFX code
    // comment out next line to have no or minimal Adafruit_GFX code
  while (display.nextPage());

void loop() {
  // Your code here

Here is the crashing message:

Sorry for the coded stack trace. Here is the decoded result:

I downloaded the sketch from Arduino IoT Cloud and uploaded it with the Arduino IDE and now it's working. Very weird

Arduino Cloud is using a very outdated version of the ESP8266 boards platform (2.5.0). From your screenshot, it appears you have the latest version of the ESP8266 boards platform (3.0.2) installed on your local computer. I think that is the most likely explanation for the different results between the two.

It is also possible that you have different versions of libraries installed on your local system. Since Arduino Cloud always has the latest version of every Library Manager library available, and uses those versions by default, it would be more likely to go the other direction, where you have an older version on your computer. But since there are thousands of Arduino libraries, it could even be that you have a completely different variant of a library on your computer, similar enough to compile, but with some divergences in the code that cause different behavior.

Thank you very much for the explanation. I'm going to investigate on this and give you the result.

I tried to link my board to Arduino IoT Cloud platform using Arduino IDE from my house and now it is not working. It was working at my work.

I updated Wifi credentials and the monitor is displaying that the board is connected to my box. But right after that, I have this message:

ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to

I tried deleting the thing, the sketch and re-create it. I tried to use 2.5.0 esp8266 package as well as 3.0.0 and 3.0.2.

Did you get the same crash like you reported at ESP8266 Feather Huzzah doesn't work with IoT Cloud - #3 by ayubowan after you uploaded the sketch to your ESP8266 board while using 2.5.0?

Here is the stack trace with the 2.5.0

I also tried the demo code from this page. It uses these files :
#include "DEV_Config.h"
#include "EPD.h"
#include "GUI_Paint.h"
#include "imagedata.h"
#include <stdlib.h>

The result are not the same. If I just include the libraries on my sketch on IoT Cloud, everything is ok. But as soon as I'm trying to display something on my epaper screen, it makes the esp8266 crashing.

I just want to display a text typed with IoT Cloud dashboard on my epaper display. I didn't find an IoT Cloud compatible library. Without IoT Cloud, my code is working and I can display what I want on the epaper screen.

I'm about to give up on Arduino IoT Cloud :sob:
I have been struggling for weeks with this project. Maybe thingsBoard ?

Do you have any idea ? I tried the Blynk app instead of IoT Cloud (to test another platform), then it makes the firmware of the ESP outputs an error.

I'm ok to use any library to control my Waveshare e-paper screen with IoT Cloud.

got the same problem same board

I bought a Lolin D32 Pro with 16 MB of RAM and now it is working perfectly !

PS: I'm using the GxEPD2 library
