I see with the eval board that I can be "connected" to the iPhone LightBlue app but I never had to do any sort of "pairing" between devices as one would do say with an automobile for instance

Hello vsesto,

Very good question.

Please look at the Blue Spec 4.1 located at https://www.bluetooth.org/en-us :

  1. Section 5.2 talks about the Classic BT Pairing
  2. In BLE, The Classic Bluetooth of Paring (Ex: using "1111") does not apply to BLE - As you referred to in your automobile.  Most BLE devices were expected NOT to have a KeyPad and LCD to enter the "1111"
  3. In BLE, connections are created between a smartphone and a peripheral without passwords using the "Just Works" method - 5.2.4.2 Just Works in the BLE Spec.
  4. The smartphone can connect to a specific device by "bonding" to it - something like "pairing" but the differences are explained in the Section 13.2 BONDING FOR BR/EDR/LE DEVICE TYPE.
  5. Also take a look at Section 4.3.1 White List on Page 2525/2684.

This should get you started.
