Hi,

Here is the fix:

Inside rank_vars_update() in peer_manager.c

 if (err_code == NRF_ERROR_NOT_FOUND)
    {
        m_highest_ranked_peer = PM_PEER_ID_INVALID;
        m_current_highest_peer_rank = 0;
    }

It seems to be a bug. I have reported this and we are looking into it.

Till now we did not, but I added this in code, and it returns NRF_ERROR_NOT_FOUND. Is it expected that data is stored without the ranking information?

Could you check the return value of pm_peer_data_load()?

Hello, i am answering on behalf of my colleague Roy,

It happens with any peer, not necessarily the same. We observe that the very first peer to bond after deleting all the bonds is assigned with rank with an unexpected value. If we restart the device after deleting all the bonds and then bond with a peer, then we don't observe the issue.

pm_peers_delete returns success and after that we see the following SDK logs(for 2 bonds):

NRF_LOG: <info> peer_manager_handler: Peer deleted successfully: peer_id: 0

NRF_LOG: <info> peer_manager_handler: Peer deleted successfully: peer_id: 1

NRF_LOG: <info> peer_manager_handler: All peers deleted.

NRF_LOG: <info> peer_manager_handler: Peer deleted successfully: peer_id: 1

Hi,

It seems to be correct the way you do it. Have you tried bond with another peer after you delete all peers? Does the same issue occur? Does it only happen when you bond with the same peer after deleting?

Does pm_peers_delete return success?
