Arduino Mega Authentication

Unable to authenticate my arduino mega, while same process is working on uno.

Hi, can you please share your code and enable the debug in the code to see what is happening?

Best.

When I compile it for Uno it works fine, but on ArduinoMega compilation error occurs for Software Serial library. As i says “mySerial” is not defined in the scope. I tried to run it by using other UART ports but then it is unable to get Authenticated on thinger.io Socket.

Hi, so, are you able to even compile the sketch and flash it to the Mega?

I an Arduino Mega, I recommend you to use a hardware serial (i.e. Serial1). This way, you can avoid using the Software Serial, and it should work better.
