Follow up question. I want to read my user data before mesh_init(). How would I do that?

Thanks.

- Yes defragmentation and power failure protection is taken care of in flash manger which mesh config running on top.
- The documentation is what we have, we don't have other guides for this module. I would suggest to read about them in the code.

In the Enocean we don't check if the storage is successful or not as we don't have other task need to wait for that to finish. But you can have a look at the restored_result_apply() function in netstate.c. persist_completed_notify() event handler is added when we do seqnum_block_allocate().

Oh, I've never even heard about the mesh config module.

- Is there some more information about how to use default values?

- If mesh_config_entry_set() returns NRF_SUCCESS, can one assume that the values have been successfully stored? The documentation mentions waiting for NRF_MESH_EVT_CONFIG_STABLE event or checking via mesh_config_is_busy(), but the enocean example doesn't do this.

- Since the backend is based on Flash Manager, I assume that defragmentation, power failure protection, etc is all taken care of?

Thanks.

Hi Ferdi,

It's not recommended to use the flash_manager directly.
Instead we suggest to use the mesh config module to store your own data instead.
You can find the documentation with example code here.
You can also have a look at our Enocean_switch example to see how it's implemented. In the example we store the state of the light switch to flash when we receive a packet.
