ArduinoCloud Not Declared In This Scope

Development Tools Cloud IoT
1

I'm working on a project that I would like to run through the IoT cloud however I'm having some problems getting the code to compile and load from the Cloud editor. The code compiles and loads just fine from the desktop IDE however I keep getting "ArduinoCloud not declared in this scope when I try to compile online. The code and error message are attached. The error populates in line 24 of the 'thingProperties.h' file right after 'void initProperties()
{' in the code. I'm planning to rework some of the code to replace the delay() with millis() just haven't got that far yet. Any help will be greatly appreciated.

Hi @hsolum. You have a stray closing brace (}) in the setup function of your .ino file:

3

Thank You for looking at this. Unfortunately, I am still having problems with the file not compiling after removing the stray brace. I have gone through it with a fine-toothed comb and still can't identify anything else that is causing the problem.

Please post your full updated sketch.

Please also post the full error output you get from compiling the updated sketch.

Not sure how much it matters but I'm trying to configure this on a Mega 2560 with a generic ESP8266 WiFi module.

7

That is the cause of the error. The library and Arduino IoT Cloud in general do not support this. You can use it when programming the ESP8266 directly, but you can not use it in sketches that run on the Mega 2560 board, even if that board is using the ESP8266 as a Wi-Fi adapter.
