RE: Using DFU Bootloader with an application on a newer SDK version

Thanks,

i didn't modify the ble_*.h at all, i just changed the loader file path to the newer SD version, and the SD ID for the DFU zip files, and everything was working fine after that. I'll use the bootloader from the v16 SDK mitigate any negative effects.

Hi Mat,

It's not suggested to use Softdevice v7.0.1 with the bootloader made for softdevice v6.1.1

Have you updated the header file (ble_*.h ) to the new softdevice's header files ? Or you simply used the same header files on Softdevice v6.1.1

Softdevice v6.1.1 and Softdevice v7.0.1 are quite similar and it may work when you replace them but there is no guarantee that there would be no problem.

I would suggest to update the bootloader to the bootloader we have in SDK v16.

Note that the current SDK is v17.0.
