Nordic nRF51822 is a SoC chip integrating ARM Cortex M0 and Bluetooth Low Energy. Its advantage over TI CC2540, which is used in current Freematics OBD-II Adapter and OBD-II data logger kits for BLE communication, is that it has a 32-bit ARM core with more sufficient processing power comparing to CC2540′s 8-bit 8051 core, while the cost is only a little higher. That means, more work which previously requires additional chip can be done in that SoC chip. With bold imagination, there is possibility to port Arduino to this chip so that it can be programmed like Arduino or Maple.
I just got a nRF51822 dev board on hand and will start evaluation shortly.
