BTLE Central Peripheral Transfer
Version 1.0, 2012-11-15
This sample shows how to transfer data using CoreBluetooth's Peripheral and Central modes.
Xcode 4.5 with iOS 6 SDK
This sample shows how to transfer data from an iOS device in CoreBluetooth Peripheral Mode to another in Central Mode, by using a CBCharacteristic on the Peripheral side that changes its value. The value change is automatically picked up on the Central side.
This sample shows how to handle flow control in this scenario.
It also covers a rudimentary way of connecting two devices using the RSSI value as an approximation of distance between them.
