BLE DFU single bank support for bootloader+softdevice update

"BLE DFU single bank support for bootloader+softdevice update". I found it in change log of SDK 7.1.0. What does it mean?

Hi,

It meant the support for bootloader and softdevice update. It erases the application to store the image the softdevice (and bootloader) so it's single bank update.

It's available from SDK v6.1, I guess we forgot to add that info into the release note of SDK v6.1&SDKv7.0 so we added in the note for SDK v7.1

@Mark Rages: I believe it's a bug in the documentation. The bootloader and the softdevice won't be erased until the images are copied correctly into the flash. The MBR taking care of bootloader replacing. So It's not really true what the documentation said " because if an error occurs and the device is left without a valid application, you can recover it by uploading a valid application again. If the device is left without a valid bootloader or SoftDevice, you can recover it only by attaching a flash tool and updating the device with a flash programmer."
