Seeing what firmware was flashed

I have a number of similar applications in my build library that I had made for a Photon some time ago. I know that it is working fine but I am not sure which one of them I had flashed it with. Is there a way to figure that out, provided I am the owner of the device?

Not really.
The common way to prevent this kind of confusion would be to add some application and version tag into the code and either print that out on startup and/or have a Particle.variable() to access that info.


Thanks. I’ll be sure to follow your advice for future sketches.
