Hi Anders Im aware that the module is experimental. I hope i can help to bring the peer manager to a stable state by reporting bugs :-). I'll try if it solves my problem. Thank you!

Hey!

It is a minor bug in the peer manager. Keep in mind that this module is experimental for now.

You were correct about the BLE_ERROR_GATTS_SYS_ATTR_MISSING event causing this issue. The functions handling this event had a logical error.

The fix: In "nRF51_SDK_10.0.0\components\ble\peer_manager\gatts_cache_manager.c", comment out lines 206-209.

//if (peer_id == PM_PEER_ID_INVALID)
   // {
      //  return BLE_ERROR_INVALID_CONN_HANDLE;
    //}

and add checks around

err_code = pdb_read_buf_get(peer_id, PM_PEER_DATA_ID_GATT_LOCAL, &peer_data, NULL);
if (err_code == NRF_SUCCESS)
{
    pm_peer_data_local_gatt_db_flash_t const * p_local_gatt_db = peer_data.data.p_local_gatt_db;
    p_sys_attr_data                                            = p_local_gatt_db->p_data;
    sys_attr_len                                               = p_local_gatt_db->len;
    sys_attr_flags                                             = p_local_gatt_db->flags;
}

like this

if (peer_id != PM_PEER_ID_INVALID)
{
    err_code = pdb_read_buf_get(peer_id, PM_PEER_DATA_ID_GATT_LOCAL, &peer_data, NULL);
    if (err_code == NRF_SUCCESS)
    {
        pm_peer_data_local_gatt_db_flash_t const * p_local_gatt_db = peer_data.data.p_local_gatt_db;
        p_sys_attr_data                                            = p_local_gatt_db->p_data;
        sys_attr_len                                               = p_local_gatt_db->len;
        sys_attr_flags                                             = p_local_gatt_db->flags;
    }
}

I hope this solves your problem

I guess that would match my observations. Then I assume this is a bug right? On iOS devices there is always a service discovery bevor bonding.

It works with Master Control Panel (windows) if i bond before doing a service discovery.

I think the problem appears after a BLE_ERROR_GATTS_SYS_ATTR_MISSING event occurs during the service discovery, but i was not able to track it down any further.

I have had the same problem. I will let you know if i find the solution
