Oh, it turns out that I didn't turn off "Erase application Settings. After turning it off, the data can be retained. Thank you.

Hi Quay,

Which DFU app are you using? This issue maybe related to the "Erase App Settings" option in your apps.

For example, by default, "Erase App Settings" is turned on in the nRF Connect App. You need to turn it off.

Below is the location of this switch in the nRF Connect App (iOS version):

If you do not need the "Erase App Settings" function via your mobile app, you can also disable support for it by setting CONFIG_MCUMGR_GRP_ZBASIC_STORAGE_ERASE=n

Best Regards,
