That is very helpful, thank you.

From the code, it does get generated from that. (it's generated on FDS_EVT_WRITE, FDS_EVT_UPDATE, FDS_EVT_DEL_RECORD success events)

Does the PM_EVT_PEER_DATA_UPDATE_SUCCEEDED event get generated on the `pm_peer_new()` and `pm_peer_data_bonding_store()` calls?

Thanks for the update. The way the fds works is that fds has a queue and data_stored=1 in PM_EVT_CONN_SEC_SUCCEEDED only tell the the flash store command is queued, not executed.

Could you try catching PM_EVT_PEER_DATA_UPDATE_SUCCEEDED event and read the bond information at that event instead ? I think it's the proper way of doing it. The event is valid for both updating peer data, and storing on the first time.

I have tested adding a delay before retrieving the bonding information and this does indeed eventually result in the bonding information being present.

As per my previous comment is there a fix in a subsequent SDK/SoftDevice?

Is there a reason the bonding information cannot be returned sooner?

As mentioned in the issue, the peer_id has the value 0 which is not the invalid peer_id value.

Why would the bonding information be available on the disconnect event, but not before?

I will try the delay and reading after disconnect, but our application really needs this to work at the point of the connection being secured.

Is there a fix for this in later SDKs?

Hi Alex,

When you received PM_EVT_CONN_SEC_SUCCEEDED event, what the peer_id was ?

I'm not sure why you receive NOT_FOUND return, but could you try to do a read after some delay ? There could be a chance that the flash store command is not executed by the softdevice (even though data_stored = 1). You can try doing the bond read after the DISCONNECTED event, it should return the correct bond information.
