I needed a NFC (ISO 15693) to BLE converter. I started out using a ST Micro NFC chip CR95HF. But I didn't have appropriate lab equipment to match an NFC antenna adaquately. So, I found that Solutions Cube had a reasonably priced and very small NFC module (BM019) that used the same chip. So as typical with my projects, I adapted to it.
My board incude the Simblee SOC, USB LiPO charger(100mA), and CP2102N USB to Serial for programming/debugging the Simblee. When connected to USB, the Battery is isolated from the load so as not to confuse the charger circuitry.
This makes for a fun combination to experiment with Simble For Mobile and Simble For Cloud applications. http://thomasolson.com/PROJECTS/BLE/Simblee/SFMnfc/
