When the fds_gc() function is executed, all bonding information in the pairing area (flash) is erased.

[AOI]

hello.

I am using nRF52820 and nRF5 SDK (17.1.0).

When the fds_gc() function is executed, all bonding information in the pairing area (flash) is erased.

My understanding was that only bonding information deleted with the pm_peer_delete() function would be erased by the fds_gc() function, but in actual operation, all bonding information in the pairing area (flash) was erased.

When the fds_gc() function is executed, will all bonding information that I don't want to erase be erased as well?
If everything is erased, is there a way to erase only the unnecessary bonding information from the pairing area, leaving only the bonding information I want to use?

Hi,

This is not expected. fds_gc() should only remove FDS records that are unused. Have you debugged to understand more about what is happening? It coudl be interesting to both see if you have some fds or meer manager calls that you are not aware of tat could delete data, or perhaps other code that could write to/erase flash in other ways?
