SoftDevice Upgrade OTA -DFU

[Stevasway]

Hi all,

I need to upgrade an nRF52 device with SoftDevice 5.0.0 and bootloader.

I have to upgrade from SD 5.0.0 to 7.2.0.

I use this command to generate the zip file:

nrfutil pkg generate bootloader+SD7.zip --hw-version 52 --sd-req 0x9D --sd-id 0x0101 --softdevice s132_nrf52_7.2.0_softdevice.hex --bootloader-version 2 --bootloader secure_bootloader_ble_s132_custom.hex --key-file custom_priv.pem

When I program new SD 7 and bootloader using nRFgo Studio everything is ok. When I upgrade by OTA then the device doesn't restart correctly.

What am I doing wrong?

Thanks in advance.

Hi,
I have question about app after this update. Did you update app after sd+bl updating? New SD is bigger than old one so app start address can change. Am I right?
