OS Service "Settings"

[nkost]

Hi,

The fstorage library is not available for NCS. Instead, the OS Service "Settings" should be used. (see the last answer of this thread)

In fstorage, it is possible to use the nrf_fstorage_sd backend to use it together with a SoftDevice. In "Settings", there are three storage backends available, one of which is for non-volatile storage, but I couldn't find an answer as to whether it is possible to use this together with a SoftDevice or where this would be handled.

So my question is, is it possible to use "Settings" in conjunction with a SoftDevice and if yes, where does the appropriate backend (or similar) gets chosen?

Thank you in advance!

Hi,

The recommended backend for the Settings module is NVS, and yes it's compatible with the Softdevice Controller. The backend is configured by applying CONFIG_SETTINGS_NVS to the project config file.

Hi Jared,

Thanks for your answer!

I suppose the same holds for the Storage module?

[Jared]

Hi there,

Not sure which storage module you're referring too? Can you specify?! fstorage?

Hi,

Sorry for the confusion, I just noticed that the NVS backend you referred me to is part of the Storage module, not the Settings module ... my bad.

My question therefore is, does the same hold for all APIs of the Storage module?

Hi,

NVS is what we have tested and used in our ble examples. Thus this is the backend that we recommend to use with our Softdevice controller to avoid any problems.
