Factory Reset function and erasing EnOcean switch data

Question

I am trying to erase the EnOcean switch data without erasing the board. node_reset() function isn't erasing the EnOcean switch data after commissioning. 
 I would like to know how to erase the switch data without erasing. 
 Also, is there any function defined to perform a factory reset without erasing the board? 
 I am investigating about a way to do a factory reset with buttons on the board. 
 
 Thank you.

Hi 
 I presented this issue to my colleagues, and while providing a patch for this, we found a bug that took some time to fix. There are two parts to patch/bug fix so follow these steps: 
 
 In the enocean example's main.c file, call `app_flash_clear(&m_app_secmat_flash [0] , sizeof(m_app_secmat_flash));` while handling the ` EVT_NODE_RESET` in the config server's event handler, as shown below: --- a/examples/enocean_switch/src/main.c
+++ b/examples/enocean_switch/src/main.c
@@ -338,6 +338,8 @@ static void config_server_evt_cb(const config_server_evt_t * p_evt)

+ app_flash_clear(&m_app_secmat_flash[0], sizeof(m_app_secmat_flash));
 node_reset();
 }
 } 
 Bug fix in `mesh_stack.c`, which will ensure that the application data is erased correctly. --- a/mesh/stack/src/mesh_stack.c

 }

 Editing these two files accordingly should make the EnOcean switch node reset work properly.
