So kudos for the Particle team: I was able to grab the sources for the firmware, modify it to add a new function in the Cellular package, compile the binaries and flash my electron without bricking it, all in a few hours. That should tell you something! This is a great platform.
But now I’m stuck: I need to change the particle.cli compiler, so that it knows about the new firmware function. I downloaded particle.cli from github, but I can’t find the place I need to change or recompile, so that the ino compiler “knows” about my new function.
Any help or pointer would be appreciated.
