iPhone Bluetooth Low Energy interface. The iPhone provides a scan and connect UI for a BLE device.
When the user chooses a BLE device, a sqlite data base holding BLE address, device names and position is checked. A UI is provided to allow the user to edit the name and position data. If the BLE address does not exist it is added to the data base.
Once SQLite data is entered the iPhone connects to the BLE device an takes two ASCII numerical strings and presents both values on the iPhone UI. One numerical value is also presented using a vertical progress bar. The iPhone closes the connection and reopens again 60 seconds later to update the reading.
