Code problem on arduino cloud ?

[benjineuf31]

Hi, I'm new to the Arduino Cloud world, and I've been experimenting with communication between two Arduino boards using an IR transmitter and receiver. I have two Arduino Nano boards; one of them is an ESP32 connected to the Arduino Cloud, while the other serves as an IR transmitter, continuously sending the same burst pattern (without using a communication protocol).

On the transmitter Arduino, I'm using pins D2, D3, D4, and D5 in parallel to drive an IR LED. However, I'm encountering an issue on the receiver side. After uploading my code, my Arduino connects to the cloud initially, but it disconnects shortly afterward for no apparent reason. I suspect there might be an infinite loop causing this, but I haven't been able to locate it.

I apologize in advance for the quality of my code; I know it's not ideal. Thank you for any assistance you can provide.

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  String BusNumber;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.
