I need an iPad BLE 4.0 app that is connected to other instances of the same app running on other iPad devices on the same LAN. Each iPad will search for and detect when a specific or small list of mobile BLE 4.0 beacon(s) are in proximity to them and report the identification of the beacon to the other iPad peers (the beacon may be a stand alone BLE 4.0 beacon sensor device or a BLE mobile device such as an iPhone 4S or other smart phone equipped with BLE capability).
The iPads will be in static locations defined on a two dimensional map displayed on the iPad screen. Each iPad will display its own predefined position on the map along with the current mobile position of the beacon or beacons as reported by itself or its peers over the LAN. Each iPad will also assume it is configured with the same .png map as its reporting peers.
The iPad app should be configurable so that for each instance of the app, a .png map can be defined. During configuration, the user should be able to also display the now defined .png map and with their finger define the static location of this particular iPad app instance relative to the map. That location will from that point on be marked with a green dot overlayed over the map (indicating the location of the iPad on the map). The iPad apps should also be configured with the beacons to be proximity detected and an alias ID for each beacon. Alias IDs will simply be a single user defined alphanumeric character (example '1','2','3...'a','b'.c')
in operating mode, after the map and all iPads in the network have been configured, each ipad will continue to display its position (using the static green dot) along with the positions of the mobile beacon(s) as reported relative to the known location of all the static iPad peers. They can do this because each iPad will broadcast to its peers the identification of a beacon when it comes into proximity along with its own pixel (or x,y) location on the .png map all the ipad apps share. When an iPad receives notification from a peer that a beacon is in proximity, it will use the peers location and display the beacons ID over that location on the map. If more than one beacon is at the same location at the same time then the second beacon to arrive will be displayed just off to the side of the last beacon to arrive so that ID's never block each other.
We will need to demo this initially using several iPads as statically located devices running the app using a common map but at different user defined locations on the common map, and one or more iPhone 4S (BLE 4.0 enabled) used as mobile beacons. Later, the mobile device will be a TI, bluegiga or TOD BLE module.
You must be familiar with Bluetooth low energy 4.0 and the IOS library routines associated with this standard as well as Objective-C and the IOS development and xcode environments.
