Hi Jo-Jo, Yes, the softdevice update feature is available on S110 v7.0. Please have a look at section 9.1 in the S110 Specification v1.3 An experimental DFU example is provided in the SDK v6.0, the documentation could be found here: devzone.nordicsemi.com/.../a00067.html

Did the ability to update the S110 ever get released? I can't find anything saying that this functionality exists. Also, what about the S120? Can we overwrite the S120 with the bootloader?

Hi Frank,

The solution to copy the code to RAM and do an ERASEALL may work, but as you mentioned it's not safe. Adding another bootloader on top of the softdevice will introduce unwanted interrupt latency, and may cause the softdevice to be malfunctioned.

Actually, in the next version of the softdevice, v7.0, there will be an added feature to update the softdevice. S110 v7.0 will be released very soon, I would say in a few weeks time.

I would suggest you to wait for this release.
