Unprovisioning a device with power on off

Question

Hi,

I tried to implement a unprovision method for provisioned devices such as light bulbs. By simply on off it several times. And saving state into flash.

Currently I'm able to save boot count into flash and able to reload if from flash. But when I tried to unprovision a device I got following error,

<t: 9519>, app_error_weak.c, 108, Mesh assert at 0x0002A86E (:0)

following lines used to unprovision a device as used in Light Switch example..

if(m_nw_state.boot_count > 4)
    {
        m_nw_state.boot_count = 0;
        
        if (mesh_stack_is_device_provisioned())
            {
#if MESH_FEATURE_GATT_PROXY_ENABLED
                (void) proxy_stop();
#endif
                mesh_stack_config_clear();
                mesh_stack_device_reset();
                __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "BOOT RESET Happen\n");
            }
            else
            {
                __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "The device is unprovisioned. Resetting has no effect.\n");
            }

    }
    else
    {
        m_nw_state.boot_count = m_nw_state.boot_count + 1;
    }

    ERROR_CHECK(store_app_data());

And I got log result as below

Is the unprovision method that I used have issues?

Thank you

Hi 
 Thanks for replying I found a solution for the above matter after trying several methods. 
 The issue was with proxy_stop() part. 
 Thank you
