DFU app

Hi, 

Is there a "stand alone" DFU updater which can be given to end user not as part as NRF tools apk?

We would like to give end user the option to update, but as simple as possible, without confusing them with all the tools in the Nordice tool set.

One more question is about DFU sofdevice. Since the bootloader uses the same softdevice as the application firware, what will happen when softdevice is updated?

How will the bootloder  continue to function?

Thanks

Johanan

  • Hi,

    Although we do not have a general stand alone DFU updater, we do have DFU libraries both for Android and for iOS, to facilitate writing your own update application.

    You can only update the SoftDevice either in conjunction with the bootloader, or if the SoftDevice major version is the same. If you update to a newer major version of the SoftDevice then you will have to update the bootloader as well in the same update. Those rules are enforced by the DFU bootloader, which means you will always have a functioning bootloader/SoftDevice combination.
