nrf54l15-dk zms +setting

[dede]

Hi,Team,

I'm using the nrf54l15-dk to develop zms to save custom configurations without affecting the pairing information of ble.

So I have a few questions:
1.Is the storage_partition in the flash_map_pm.h file the same as that in the nrf54l15_cpuapp_common.dtsi file? If the same, does this mean that the size of settings_storage is 36K?  Is settings_storage the area used to store ble configuration information?

2. My nrf54l15-dk has some errors. Why is that? network/info, hub/info and first_run/check are custom configurations. I save them using settings_save_one and then reset the device, and an error E: set-value failure occurs.

3. Through the error in the second one, I think both the custom configuration and the saved ble configuration information were saved in storage_partition, resulting in the error. So I want to ask whether storage_partition can be divided into the pairing information area of ble and the user-defined configuration information area.

Thanks.

Hi,

1.Is the storage_partition in the flash_map_pm.h file the same as that in the nrf54l15_cpuapp_common.dtsi file?

If you use the partition manager, the DTS one is ignored, and partition manager partitioning is used instead.

Is settings_storage the area used to store ble configuration information?

settings_storage is used for Settings, so yes.

2. My nrf54l15-dk has some errors. Why is that? network/info, hub/info and first_run/check are custom configurations. I save them using settings_save_one and then reset the device, and an error E: set-value failure occurs.

But you can store other stuff first, or?

3. Through the error in the second one, I think both the custom configuration and the saved ble configuration information were saved in storage_partition, resulting in the error. So I want to ask whether storage_partition can be divided into the pairing information area of ble and the user-defined configuration information area.

Yes, I think it shold be able to use settings for both your app and for BLE.
Try to make the settings partition larger, does that help?

Hi,

How to divide storage_partition into the ble pairing information area and the user-defined configuration information area.

Thanks.

As you can see here, the settings ZMS backend is hard-coded to use one partition. Therefore, Settings will use the same partition no matter what part of the application uses Settings.

Alternatives are:

Try to increase the size of thesettings partition to check if that solves your issue.

Use another storage subsystem for your application.
