I wonder if you’re getting tinker back by mistake?
Could you try adding some Serial.println() calls in setup()/loop() to see if they are present.
Are there any functions/variables exposed?
In the linked zip I’ve got everything present.
The RGBTest.ino which I expected to get built has this in setup()
Particle.function("testCode", setCode);
But it’s not exposed - neither are any Tinker functions.
I’ve tried the .ino in all “possible” and “impossible” positions, but never got a 20K binary - only ever 6K
