    I am working on a portable wireless heart monitor with Bluetooth interface. The idea is to measure ECG signals for at least 1 day straight and then transmit data to the Android device. According to my research I believe that TI's ADS family would probably be the most suitable for my case, specifically ADS1293, which is in short all-in-one ECG chip.

    I am now searching for a suitable microcontroller with Bluetooth capability which would acquire the signals from ADS1293, save them to external flash memory and then transfer them to the phone over BT/BLE. The original idea was to work with Arduino, but then I came across SoC TI CC2640. It obviously looks really suitable for my case at first glance since it's dimensions are small and it also has low power consumption, but so does Nordic nRF52832. I've already searched all related forums for comparison between these two and people seem to prefer nRF52832 a bit more over CC2640. However, TI already has a very similar project design like mine here. Code is already provided, but the project is designed with CC2541, which is not compatible with CC2640 though, but I suppose that this would still help with coding.

    Since I basically don't have any previous experience with these platforms, I was wondering which MCU+BT/BLE would you recommend to me? An important factor here is also that the development process should be as cheap as possible since I am a student, so the price of debuggers, development boards and software should also be taken into consideration.
    Should I rather choose any other MCU e.g. like RFdroid or would you have any other recommendations? I would really prefer a well supported MCU for faster development process and quicker learning curve.

    Thanks for help and any suggestions in advance.

    What's wrong with the CC2541?

    It doesn't support BLE and it has to be programmed with IAR Embedded Workbench because of the 8051 MCU, which is therefore too expensive.
