Temperature logger

[Kurt]

Hello, I would like to develop a temperature logger which Starts to log temperatures between certain limits
The data is stored until the device has connectivity to the iPhone. It then pushes the Data to the iPhone and the process starts over again. Best would be if radio Connection gets active above a certain temperature. All this should be:

• tiny
• Wireless, i.e. Ble, Driven by cr 2032 3V battery.

Which device should i Take to realize this Project? Is there a dev kit and sample code for xcode available?

Thank you so much for your help,

Curt

Dear Petter, dear Ole, thank you very much for your hints. I was searching in the same time and ran into the rfduino product which is built on the nRF51822 chip, so it's exactly what I am looking for. The programming language is easy to start and as far as i can see there are also some projects ready to run with ios. Your SoC is exceptional! I didn't find the way to use it so handy until now. As described at arduino forums the development of the temperature logger and the resistance logger couldn't be impossible. I will give some sample code when I am done. Best Regards Kurt
