Project Description:
Develop a simple bluetooth remote control unit that is controlled from an Iphone 4s app.

Write software for a Bluetooth CC2540 Module ( The software should enable 4 digital input lines, 4 digital output lines, and 2 ADC channels on the CC2540 module.

Write a simple Iphone App that provides bluetooth connectivity between the Iphone and CC2540 module. The app shall periodically (for example every 2 seconds - user configurable) poll the CC2540 and indicate the state of the digital input lines and ADC channels and provide the ability to change the state of the digital output lines from the IPhone App. For the UI, I just need 4 toggle switches to change the 4 digital output lines, 4 check boxes showing the state of the 4 digital input lines and 2 label boxes showing the value of the ADC channels. Basically I need the framework for a very simple remote control.

I would also like the Iphone app to be able to read the Digital Received Signal-Strength Indicator (RSSI) of the CC2540 module and have a label box that indicates the approximate distance to the CC2540 module.

To make the project easier/faster, I do not want to mail hardware back and forth. I would expect the freelancer to obtain the equivalent CC2540 module at their location, write the software for the module and the Iphone app and email to me for onsite programming and testing.

The CC2540 Module that I will be using is
