Hello,
I have an Arduino 101 with the Intel Curie and I noticed that, no matter what i do over serial, the TX/RX LED (they are bundled into one on the board somehow) will not light, I do not have a multi meter at the moment so I would check for a diode effect. Is this LED only for Bluetooth or something else other than serial? I looked online but nobody else has brought this up so I'm pretty sure that LED should be flashing.
