mhahn Thanks again for the article. I've read it and it's a good reference.
Following that topic I was wondering of maybe it would be possible that serial communication from Arduino could be handled/intercepted by Yocto running on Edison? From my understanding Arduino uses Edison's serial port capability to communicate with an external PC. Could Yocto actually use this to communicate a node.js app with Arduino sketch for example? It would also allow for super simple data exchange between running applications
