I am trying to shrink my project down to fit the dimensions I am looking for but I would like to still use the Arduino IDE because its so convenient and so I can make changes easily. I want to design my circuit for a PCB and use only the esssential parts I need to save space. I don't know if I need to use the Cortex Debug Connector and the Serial Program Debugger to do this. ->SparkFun Breakout Board Schematic
Everything I have seen about just programming a bluetooth chip just uses ATcommands. I have never downloaded firmware onto a chip like this before and wanted to see if anyone has any advice.
