Hi,

It appears as if the bluetooth shield cannot work with the coin cells on the board. The most convenient other way to get power while developing, is to plug in a USB cable into a computer via the USB shield. So here is the question - can I plug the bluetooth shield and USB shield onto the Arduino and use the bluetooth shield for communication and the USB shield purely to draw power?

Yeah, the Bluetooth shield takes a lot of power. There are connections where you can hook up a bigger battery to the TinyDuino

Hi Nikhil,

Unfortunately the standard BT shield uses the same hardware UART pins as the USB TinyShield, so they are not able to be used at the same time.
