Programming nRF51822

[Dani]

Good morning, I have been playing with the EV-Kit and now I want to design my own application. I would like to know if is it necessary to include Segger (J-Link) IC in order to program and debug the nRF51822 device. What I really need is to find a solution in order to easily program (S110+App) my own modules without the need of being forced to use Keil or similar. The best way would be to program the modules in any computer through the serial port: some ARMs have this performance and they allow to flash the device through the computer (by means of a computer application) by using the serial port (ARM allows this mode by asserting a certain pin). Furthermore, does the nRF51822 allow to be programmed via OTAU using bluetooth?

Best regards.

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.

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?
