The RN52 is kind of a pita to solder...so i would def check there first. make sure each connection is good, clean, and no shorts.

Yep, no kidding. There's a line in the RN52 product brief that says, "Castellated SMT pads for easy and reliable PCB mounting" LOL

The top side was a piece of cake in comparison - my first ever experience doing SMT (I used a stencil + solder paste + hot air). But for the bottom side RN52, I applied too much solder paste and created some bridges. I cleared the shorts, but the device was not discoverable. I removed the RN52, cleaned the pads and soldered it back in, but still the same behavior.

Since comms with the IHU are happening, can I assume that the Atmega flashed successfully? I did not follow the recommended procedure, but instead flashed the blank Atmega in an Arduino board connected via ICP to a USBasp.
