Handling the PM_EVT_CONN_SEC_CONFIG_REQ in pm_evt_handler solved the issue. case PM_EVT_CONN_SEC_CONFIG_REQ:
{
 // Reject pairing request from an already bonded peer.
 pm_conn_sec_config_t conn_sec_config; // = {.allow_repairing = true};
 conn_sec_config.allow_repairing = true;
 pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
} break;
