    Zm, hi.

    The RXD and TXD led lights on the Cyton indicate that data is moving across the COM port usb serial link. This is normal. TXD flashes briefly as packets flow from the RFDuino radio to the usb. RXD flashes briefly as usb packets are received by the RFDuino, and then sent over the Bluetooth link.

    Regards,

    William
