Hey all! New to posting in this community but have been a lurker for quite some time. Really enjoying hacking my new Photon. One issue I’ve had over the years of hacking MCUs is forgetting what program I had flashed onto them. Particle’s cloud API helps remedy this by exposing remote function calls…

You can do something like Spark.publish("app-name:) in setup() for now if you need something that works :smiley:

[image] kennethlimcp: You can do something like Spark.publish("app-name:) in setup() That's very similar to what I've done. Having a constant available however just makes it simple, since the expectation is that it would always contain the correct/current value.

What about using the C++ standard predefined macro to put the file name into the code? #define COMPILED_FILENAME __FILE__ const char * programVersion = COMPILED_FILENAME;

[image] BulldogLowell: #define COMPILED_FILENAME __FILE__ const char * programVersion = COMPILED_FILENAME; Excellent suggestion! I'm going to include that snip in all of my apps. Thanks!

:blush: also, you can strip out all of the cloud path stuff like this: const char * fileName = (strrchr(programVersion,'/') + 1); Particle.variable("pgmVersion", fileName, STRING); and note the change in file extension, that the compiler does: [image]

@BulldogLowell cool! Can you share the full code snippet? I copied both and pasted but doesn’t compile Also, i opened an issue here: https://github.com/spark/docs/issues/180 if you don’t mind us sharing as an example!

no problem: [image] #define COMPILED_FILENAME __FILE__ const char * programVersion = COMPILED_FILENAME; void setup() { const char * fileName = (strrchr(programVersion,'/') + 1); Particle.variable("pgmVersion", fileName, STRING); } // void loop() { }

you can make it more compact (I wanted to show the variable type returned in the example) and use other C macros as well: void setup() { const char * fileName = (strrchr(__FILE__,'/') + 1); char fileInfo[125] = ""; sprintf(fileInfo, "Filename: %s compiled on %s at %s UTC", fileName , __DATE__…

Hi, I’m reading this forum since some days and new the Particle community. I tried to run the code above on my Photon (firmware 0.4.5) and simply copy & pasted it to the Web IDE. Unfortunately it does not work for me. Only __FILE__ has correct value while __DATE__ & __TIME__ are empty. Any idea wh…

to be honest, I only tested using Particle Dev. it looks like an issue with sprintf() on the Build IDE. Try this: void setup() { const char * fileName = (strrchr(__FILE__,'/') + 1); const char * theDate = __DATE__ ; const char* theTime = __TIME__; Particle.variable("pgmVersion", fileName,…
