new build of dro, no function at all
#1
Shocked 
My TouchDRO did not function at all on the initial power up.  I double checked the soldering and found nothing wrong.  The bluetooth also does not appear to function.  It did not show up on a scan for devices.  I have no scales connected yet.  Power voltages are correct on all ic's and on the bluetooth adapter.  No signal activity was observed on any of the micontroller pins.  Static high levels were present on pins 1,3,4,8,10,11,13,18,and 19.  It seems likely the microcontroller isn't running.

At this point I don't know what to do.  Any help is appreciated.

Problem solved...missing resistor. Glad it was that simple.
