Thanks for your answer.

The Display hath the smallest battery, so we will choose the display as peripheral device.

The part you quote from the specification is a "should", so you're not really bound by this. In general, I'd recommend you to make the device with the biggest battery be the Central device, and the other device the Peripheral. The reason is that scanning for Peripherals advertising is a current-intensive operation.

Also, one thing to consider is that Android is currently not capable of being a Peripheral, so if you want to support this platform, you're most likely better off letting your devices be Peripherals and that the phone is the Central.

It sounds as if it should be perfectly possible to have the Display be a Peripheral, that the iPhone will connect to as soon as it is within range.

You can store whatever information you want in flash, including for example which device to connect to. A future SDK version will include a module making this easier.
