We will send data to an RFduino from our MCU over UART. We want to have the RFduino accept the data and send the data to an iPhone App, and have the iPhone app log the data in a .csv file. And then when the logging is done, be able to email the .csv file.
We will do all the programming on our MCU and we will outsource the RFduino & iPhone App programming.
See the attachment for details.
