Quick question. I have this setup where this board is programmed to send data to the spark core and then the core takes this data and sends it to a web site. For some reason whenever the serial terminal is open for both the spark core and the board that is sending data to the spark core, the Core stops sending and receiving data. Does anyone know why this would be?
What board are you using to send data?
And could you post the code for both the sending and receiving boards? That would be of great help when it comes to diagnosing the issue.
