Correct, the error message can be ignored, no actual issue exists.

Fix to get rid of the error message is here:

Hello,

This issue appears to be related to the CONFIG_BT_SETTINGS_CCC_LAZY_LOADING feature that's enabled by default. When enabled the bt_ccc handler does not get registered in gatt.c but it still attempts to load CCCD settings on startup as if lazy loading was disabled, hence the error. However, despite the warning, the settings are correctly restored on connection, so it seems like it should be safe to ignore this message for now. I will report it as a bug internally.

Hi,

I see it now. I was able to replicate this with NCS v1.3.0, and it appears to only happen after a reset, and only for the CCC settings. I have to investigate further to find out why this is.

Unfortunately, it's another issue, as I consider. Simon described a problem of a re-pair process, but the problem of an error kinda "E: set-value failure. key: bt/ccc/2047da12f4e80 error(-2)" after resetting is still actual.

Hi,

Sorry for the delayed response. Looks like this is related to the other question you posted here: https://devzone.nordicsemi.com/f/nordic-q-a/64583/errors-after-unpairing-devices-and-further-attempts-to-bond-them? Let me know if that's not the case.
