I don't know well enough to start with new platform, I prefer like to try use PI and get experience before run on the Edison
here is some spec about Edison
Edison OS support either Yocto and linux
I already test node-red in Yocto, and use python MRAS GPIO control arduino, LED, OK, but still need to test the PWM, I2C and the D/A, A/D ..etc, hope can be done soon
another path load the sketch inside arduino and call up firmata, but I still have problem the virtual USB doesn't recognize, don't have the answer yet, it works communicate with ioT bluemix foundation, but after I rebuild new image then not work. in theory, should work, just me
As me, I am at the learning state for all the new things happen, I like to help in the project in long run as now I am very new, new language and hardware setup..
or tell me how to setup nodejs server and testing procedure, let me try on my Yocto, so I can learn also
