As seen in the documentation, DFU/Bootloader is different if it applies via UART or via BLE. It is possible to allow a device be updated both via UART and BLE? Furthermore, and with relation to the first step, when a device is bare: is it possible to flash it (at least, bootloader and/or Softdevice) without the Segger tool or any other tool, and just flash it via serial port?

You can use bootloader to upload the code via UART (you can check the bootloader project in the sdk, single(dual)_banl_hci) , but without debug possibility. We also experimented with STM32F3DISCOVERY (ST Link/v2) like a programmer.

Yes, by default the chips come blank from Nordic so an initial programming step is needed. An alternative would be to arrange for them to be pre-programmed by your distributor, but they do charge for that.

Thank you very much John and Nils. Furthermore, I have read that SD110-v7 includes the possibility to use OTA also with the SoftDevice. But, I suppose that this can be done once the device is not bear, isn't it? So, first step is to flash device with the tool John suggested, for instance. Right?

DFU does work very well for already programmed parts. But Dani may have to deal with bare parts that were just purchased and built onto their design. One solution that I believe our production people are planning to use is something like this:

Segger Flasher

I provide them with a hex file containing the stack, DFU bootloader and our application. The load it onto the Segger Flasher and then can program our boards quickly. All it requires is that the proper pins be brought out to someplace on the board that the Segger can connect to. We bring them out to a small header, but you could even use bare pads on the board if you wanted to.

Hi, i think the easiest way to copy a new firmware to your applications memory is to use the DFU OTA (Device firmware update over the air) functionality. I would use it for my application because if you use an nrf51822 with BLE then it is the easiest way nordic provides for developers :)
