Bonding information issue when only one side the bonding is delete

[annapalu]

Hi,

sometimes not always, the function peer_id_is_allocated return false and this causes an ASSERT of device, because a NRF_ERROR_INVALID_PARAM is returned by pdb_write_buf_get. And Peer_Manager return an assert.

Someone can help to me, why this happens?

Thanks, Anna

Which SDK version are you using?

Hi petter, sdk 11

If pdb_write_buf_get() returns NRF_ERROR_INVALID_PARAM this should be the reason:

 * @retval NRF_ERROR_INVALID_PARAM  Data ID or Peer ID was invalid or unallocated, or n_bufs was 0
 *                                  or more than the total available buffers.

Does this give you any useful hints to why you get this error? If not I think you need to include some more code, or maybe even your complete project, so I can try to reproduce.

No, it doesn't. This happens when i delete bonding information first from phone side, and after on nordic evaluation board. But not always, only sometimes. But this cause the reset of device so can be a problem

The problem is here:

ret_code_t pdb_write_buf_get(pm_peer_id_t       peer_id,
                             pm_peer_data_id_t  data_id,
                             uint32_t           n_bufs,
                             pm_peer_data_t   * p_peer_data)
{
    VERIFY_MODULE_INITIALIZED();
    VERIFY_PARAM_NOT_NULL(p_peer_data);
    VERIFY_DATA_ID_WRITE_BUF(data_id);
    if (   (n_bufs == 0)
        || (n_bufs > N_WRITE_BUFFERS)
        || !pds_peer_id_is_allocated(peer_id))
    {
        return NRF_ERROR_INVALID_PARAM;
    }

the function pds_peer_id_is_allocated(peer_id) return false. But this happens after i delete the bonding information.

If i read the comment says:

/**@brief Function for finding out whether a peer ID is in use.
 *
 * @param[in]  peer_id  The peer ID to inquire about.
 *
 * @retval  true   peer_id is in use.
 * @retval  false  peer_id is free, or the module is not initialized.
 */
bool pds_peer_id_is_allocated(pm_peer_id_t peer_id);
