How large is the size peer manager uses?

[Haruki Kawakami]

I'm trying to determine DFU_APP_DATA_RESERVED and FDS_VIRTUAL_PAGES. According to this Q&A, DFU_APP_DATA_RESERVED must be the same FDS_VIRTUAL_PAGES, if FDS_VIRTUAL_PAGE_SIZE is 1024.

My application uses 11 pages, so 11+the size peer manager uses must be FDS_VIRTUAL_PAGES( and DFU_APP_DATA_RESERVED). Is this right?

However, I cannot find how large size peer manager uses is.

Would you tell me the size?

Where did you get "if FDS_VIRTUAL_PAGE_SIZE is 1024" from?

Do you want to reserve your complete application? Don't you just wanted to reserve the part of flash that FDS uses?

You should find the value of FDS_VIRTUAL_PAGES in your application, you can search for it, but usually it is found in sd_config.h, and unmodified the value is 3. Then DFU_APP_DATA_RESERVED should be set to 3.

I can define 1024 or 2048 for FDS_VIRTUAL_PAGE_SIZE, right? I choose 1024, and this is the same as CODE_PAGE_SIZE in nrf_dfu_types.h.

I want to preserve complete application data on DFU. And I know 11 pages are used for my application data, but it is not clear how much pages peer manager uses. I want to preserve both my application data and peer database.

So please tell me how much pages peer manager uses.
