Arduino start selling Arduino 101, powered by an Intel Curie processor.

As far as I have seen here, Intel Curie module integrates nRF51822.

I was wondering how we could use deeply the Intel Curie, behind the arduino part, implementing a RTOS which will be released this quarter.

I was also wondering how the nRF51822 is implemented in the Curie Module, I expect it to be interfaced with the Intel CPU on an UART link. That's meaning that this nRF51 is just used for the BLE part, and we could just program an OS on the Intel chip part.

For future reference:

The Intel® Curie™ module includes a Nordic* nRF51822 that is interfaced to the SoC (Intel® Quark™ SE microcontroller) via UART0.

We have no information about this here at Nordic. How the nRF51822 is implemented in the Curie Module you have to ask Intel about. I would guess that the nRF51 is interfaced with the Intel CPU over UART as you say, but how this is implemented we don't know.

Hi, but the Datasheet in page 21 & 22 say: JTAG programmer (Flyswatter2* or J-Link) supported by the Intel® Quark™ SE microcontroller can be used to load the image. For downloading to the Bluetooth low energy block, refer to the Nordic website.

Okay, I guess things have changed since I answered this a year ago. Seems like you need to flash the BLE stack provided by us to the nRF51 chip first? You can find the stack (called softdevice) on this page: http://www.nordicsemi.com/eng/Product.... And you can download the image with a J-Link programmer or similar that supports the SWD interface. But check with the Intel Curie documentation first if this is necessary or not.
