C2540 BLE discovery by iPhone6

I am trying to connect a C2540 BLE module to a Multiwii Pro which uses a Atmega 2560 cpu. My understanding is that the C2540 should at least advertise itself if VCC3.3v and GND are connected, but I see nothing on the iPhone when I turn on Bluetooth in general settings. It just says my phone is discoverable. Any ideas? I am trying to wire up the module directly to use for serial communications to a Multiwii configuration app.

Just CCC, GND, and TX/RX. Are there other connections that need to be made for BLE?
