Hi Alev,

You are correct, the current version of S120 (v2.0) supports peripheral role and you can use the same bootloader on S110 to do DFU, with minor modification:

Change the include path to point to the API headers file from S120 instead of S110.
Add ble_enable_params.gap_enable_params.role = BLE_GAP_ROLE_PERIPH; into ble_stack_init() to initialize the softdevice to start as peripheral
Configure the IRAM1 start address to match with the RAM requirement on S120

Currently we don't have an official example in the SDK but I attached here the bootloader on SDK v8.0 that is modified to work with S120, please copy it to \SDKv8.0\examples\dfu to compile.

bootloader_S120_SDK8_0.zip

3.You can develop the bootloader as standalone project. You will have a separate hex file that you can flash it to the chip after you flash softdevice.
