zgp_init_by_scheduler not call at first startup of my device

Question

Hello, 
 I have a project of a device with 2 endpoint plus the GP endpoint (242). It's a coordinator. 
 at first startup, the green power endpoint doesn't appear in the response of a node descriptor request. 
 if I reboot my device, the GP endpoint appear in the response of the node descriptor request. 
 
 I have found that during the first boot, the zgp_init_by_scheduler function, from libgppb.a is not call. 
 Is someone have some information about what is wrong in my device please ? 
 
 Best regards, 
 Jean-Philippe

Hi Jean-Philippe, 
 This is before both zboss_start_no_autostart() and zboss_main_loop_iteration(). 
 In the SED/light switch example button 3 is set as SLEEPY_ON_BUTTON. It is implemented in such a way that if you press button 3 while resetting or turning on the board, then SED behavior will be enabled. This is done by checking if the button is pressed before zboss_start_no_autostart() is called. 
 So in your case something similar might be to either have one of the roles as default (e.g router), and holding in the button while resetting/powering on the board will set the other role instead (e.g. coordinator). Or you can use two different buttons and set the role depending on which button is pressed. A simple implementation of the first could be something like this: 
 /* Note: BSP_BOARD_BUTTON_2 is button 3 on DK*/
#define DEVICE_ROLE_BUTTON BSP_BOARD_BUTTON_2 /**< Button ID used to determine device role (pressed means coordinator). */

/**@brief Function to set the device role according to DEVICE_ROLE_BUTTON state.
*/
static void device_role_setup(void)
{
 if (bsp_button_is_pressed(DEVICE_ROLE_BUTTON))
 {
 /* Coordinator role */
 /* Set channels on which the coordinator will try to create a new network. */
 zb_set_network_coordinator_role(IEEE_CHANNEL_MASK);
 // Add if you have any other coordinator specific things to set on start-up
 }
 else
 {
 /* Router role */
 /* Set static long IEEE address. */
 zb_set_network_router_role(IEEE_CHANNEL_MASK);
 zb_set_keepalive_timeout(ZB_MILLISECONDS_TO_BEACON_INTERVAL(3000));
 // Add if you have any other router specific things to set on start-up
 }
}

/**@brief Function for application main entry.
 */
int main(void)
{
 zb_ret_t zb_err_code;
 zb_ieee_addr_t ieee_addr;

/* Initialize timers, loging system and GPIOs. */
 timers_init();
 log_init();
 leds_buttons_init();

/* Initialize Zigbee stack. */
 ZB_INIT("my_device");

/* Set device address to the value read from FICR registers. */
 zb_osif_get_ieee_eui64(ieee_addr);
 zb_set_long_address(ieee_addr);

device_role_setup();
 zb_set_max_children(MAX_CHILDREN);
 zigbee_erase_persistent_storage(ERASE_PERSISTENT_CONFIG);

...

/** Start Zigbee Stack. */
 zb_err_code = zboss_start_no_autostart();
 ZB_ERROR_CHECK(zb_err_code);

while(1)
 {
 zboss_main_loop_iteration();
 UNUSED_RETURN_VALUE(NRF_LOG_PROCESS());
 }
} 
 Note: this is a simplified version of main(). You might have to add more to the router role configuration, and/or have a global variable to keep track of the role if you want to do things only if it is a specific role. 
 Hope this clears up what I was trying to say earlier. 
 Best regards, 
 Marte

Hello, I check with the CLI example, which doesn't have the problem. So, I think the problem is only in my project. 
 PanId is 951B
