Post DFU losing user defined storage NVS data.

mohd.alee

MCU: NRF52833

SDK: NRF 2.6.0

We are storing user data on NVS at "settings_storage" address. This helps with our application opertaion.

We have also added OTA DFU to our application, it is observed after a successful OTA update from "NRF connect" app our stored user data from NVS is erased.

Kindly guide us to retain the NVS data post DFU update.

    Hello,

    It seems that this issue may be due to a default setting in the nRF Connect mobile application. A similar problem has been reported in the nRF Device Manager app. To resolve this in the nRF Connect app, you need to disable a specific option. You can do this by navigating to Settings > MCU Manager Options > Erase Application Settings. These settings can be accessed by clicking on the three-bar menu icon located to the left of the "Devices" tab on the main page.

    We are actively working on this issue, and it will be addressed in upcoming releases. Please let me know if this resolves the issue or if you're still experiencing any problems 

    Kind regards,

    Abhijith
