BLE DEV.N (Bluetooth Low Energy Board) Digital Thermometer, Part 1

I was wondering what kind of sample to create in order to show how easy is to debug and connect BLE DEV.N board to an iOS application. Decision is made, let’s be a Digital Thermometer. Project is still in development. Final goal is board to talk with iOS BLE enabled application.
Here is hardware layout, BLE DEV.N board + DHT22 + one resistor of 10k ohm.

Code can be found here: Github.

Next steps are, implementation of the BLE layer and iOS application which can read the temperature and humidity from the setup.
