When you apply power to the +/- pins, power LED should come up and BT1/BT2 LEDs should flash alternatively. The reason you are only seeing power LED coming up is like you said - there's no bootloader on ATMEGA328P-PU chip yet, so it can't "turn on" the software and pull the pins accordingly to apply power to RN52 Bluetooth chip.

Long story short - you should burn bootloader onto ATMEGA, then flash the chip with the latest code and then you should see power, BT1 and BT2 LEDs come up.

Good luck! :)
