The bootloader is included in the SDK, so you should be able to find it there. The service integrated into an application isn't yet available, so that's something you'll have to build yourself.

Yes - I found it (not experimental anymore ehh :-)

Well, I think there is enough fuel to get me going with something like you describe here. Thanks a lot :-)

Have you seen the firmware update example that is available in the latest SDK, version 4.4.1? It receives an image with Write Commands from a Central to the Peripheral, which should give similar performance as Notifications the other way.

The SDK example includes the bootloader as a separate application, that is by default run when a button is held during boot, but by using GPREGRET, it should also be possible to make this run when a certain characteristic is written for example. Take a look at this for an example.

Another option is to take the service defined there and integrate it into your own application, making sure that the firmware image is written to a swap area, and when finished set some flag, reset and let the bootloader copy the downloaded image into the main application area.
