dm_device_delete_all(& m_dm_app_id); doesn't work

[Mikhail]

I use SDK9 nRF51. I use white list. When I want to delete all bounded devices, I call this function. But it doesn't work. It not deleted. Why I can't to delete bounded devices?

Hi, are you not getting any DM_EVT_DEVICE_CONTEXT_DELETED events after calling this api? There should be one event for each deleted entry.

Example (does a sys reset once finished):

static uint32_t device_manager_evt_handler(dm_handle_t const * p_handle,
                                           dm_event_t const  * p_event,
                                           ret_code_t        event_result)
{
    uint32_t err_code;
   
    static bool device_delete_all_started;

    // Recovery in the event of DM_DEVICE_CONTEXT_FULL
    if(event_result == DM_DEVICE_CONTEXT_FULL)
    {
        /* Clear all devices from the bond table*/ 
        err_code = dm_device_delete_all(&m_app_handle);
        APP_ERROR_CHECK(err_code);
        
        device_delete_all_started = true;
             
    }
    if (p_event->event_id ==DM_EVT_DEVICE_CONTEXT_DELETED)
    {
        
         /* Wait for all devices to be cleared before perfoming a sys reset */ 
         if(device_delete_all_started && (p_handle->device_id == DEVICE_MANAGER_MAX_BONDS -1))
         {
             err_code = sd_nvic_SystemReset();
             APP_ERROR_CHECK(err_code);
         }
         
    }
