HID, DFU fota nrf51

[Epasta]

Hi, I have seen that on mbed compiler, there is a bootloader that include the DFU and with this, we should not implement DFU in application.

In keil, we must implement dfu on application?! or we can found a bootloader with dfu integrate?!

If I have paired nrf51 as iPhone, the dfu With fota works or not?!

And how can I add dfu at HID_mouse application?!

Thanks Enrico

You need to flash the bootloader and an application that has been extended (add the DFU Service ) with DFU Support. The memory layout of a nRF51 flashed with a bootloader is shown on this Infocenter page.

This page on our Infocenter explains how to add DFU support to an application.

Did you flash the S110 Dual Bank Bootloader (examples/dfu/bootloader/pca10028/dual_bank_ble_s110) to the nRF51822 along with the S110 SoftDevice and the s110_with_dfu example (examples/ble_peripheral/ble_app_hrs/pca10028/s110_with_dfu)?
