Uploading to the M4 Co processor of the Opta Wifi

Hello, I am new to coding. I am having trouble uploading to the opta's m4 co-processor core with the sketch generated by Arduino IoT cloud thing. I can upload it the the main core just fine but when I try to load the program in to the m4 core I get error messages saying "error: 'ConnectionHandler' has not been declared", "error: 'ArduinoCloud' was not declared in this scope", " error: 'ArduinoCloud' was not declared in this scope", "error: 'ConnectionHandler' does not name a type". I also need to upload a IDE PLC code into the opta as well.

I've merged your two topics on the same subject. It's called cross-posting and wastes peoples time.


I'm not an Opta user so have no idea.

Hi @tygrun
I suspect the Opta has the same M4 limitations as the GIGA R1 WiFi, namely:
The M4 does not support:
