How to unprovision nrf Mesh DK board using the hardware?

[raulp]

Hello, 

I am using nrf52832 with nrf Mesh DK. Is there a way to unprovision the board from the hardware  or command line and not from the app?

Many thanks in advance ,

Hello , 

I had a look at it but I am not getting how it is related with my question?

My question is simple

"Is there any hardware button on the nrf5832 evaluation board which can un-provision the board" ?

Yes or No.

If Yes , then How?

many thanks in advance !

Yes, button 4 (3 in the code in button_event_handler() ).  I'm referring to lightswitch example.

Hi Hung,

I am attempting to reset a provisioned node inside the main function. I took your advice and used the code from the light switch server example (as seen below). Whenever this gets called however I am getting a mesh weak error  "app_error_weak.c, 108, Mesh assert at 0x0002BFEE (:0)". I am on the latest SDKs. I figured out that the function causing the error is "mesh_stack_config_clear". Any ideas on why this might be happening or any ideas on another way to reset a provisioned board from the main? 

 if (mesh_stack_is_device_provisioned())
            {
#if MESH_FEATURE_GATT_PROXY_ENABLED
                (void) proxy_stop();
#endif
                mesh_stack_config_clear();
                node_reset();
            }
            else
            {
                __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "The device is unprovisioned. Resetting has no effect.\n");
            }

Hi Brad, 

When you see an error, you can use addr2line to translate the address to the line of code for further debugging. Or you can step inside mesh_stack_config_clear() to see what exactly throwing error. 

Have you tested the light switch server example to press button 4 on the board to erase provisioning data ?
