Why gpiote_init used 2 times?

 and then again called in led_start for what purpose it used in 2 place.

You have two gpiote_init() functions. 
 In main.c: 
 static void gpiote_init(void)
{
 APP_GPIOTE_INIT(APP_GPIOTE_MAX_USERS);
}
 
 And in led.c: 
 static void gpiote_init(void)
{
 // Configure the GPIOTE Task to toggle the LED state.
 nrf_gpiote_task_config(GPIOTE_CHAN_FOR_LED_TASK,
 ADVERTISING_LED_PIN_NO,
 NRF_GPIOTE_POLARITY_TOGGLE,
 NRF_GPIOTE_INITIAL_VALUE_LOW);
}
 
 These are both static functions, meaning that they do not "exist" outside the file that they are declared in.
The gpiote_init in main.c initializes the GPIOTE module with APP_GPIOTE_MAX_USERS, while the one in led.c makes use of the GPIOTE task and configures it. The PPI module then assigns the NRF_TIMER1->EVENTS_COMPARE[0] to the previously configured GPIOTE task.
