uart communication problem !!

[hrg]

am using nrf51822 chip communicating with PIC16fl1509 through uart.the PIC will send the temperatire values through uart to nrf51822. i have a doubt ! will the uart communication only works after advertising ??? can i read the values before advertising and store in an array ,later diaplay during advertising ????will the uart reading functions from pic will work before all the basic functions like ble_stack_init();bond_manager_init();gap_params_init();advertising_init();services_init(); application_timers_start(); advertising_start()etc?? am trying to use uartget data before these but its storing zero in the array !! wats is the problem ?? !! pls help !!

here is the snippet of code. without using delay am getting only zeros.if i use delay am getting atleast one byte of data under manufactur field !! . is the problem with nrf51 uart ?? because after pairing am getting the temperature data!!

initVaribles(); simple_uart_config(RTS_PIN_NUMBER, TX_PIN_NUMBER, CTS_PIN_NUMBER, RX_PIN_NUMBER, HWFC);

	 {

	NVIC_EnableIRQ(UART0_IRQn);	
           nrf_delay_us(2000000);
    TaskGetDataFromPIC();
          nrf_delay_us(2000000);
     NVIC_DisableIRQ(UART0_IRQn);

           }
//leds_init();
timers_init();
gpiote_init();
buttons_init();
//data from pic 	

ble_stack_init();
bond_manager_init();
gap_params_init();

services_init();
sensor_sim_init();
conn_params_init();
sec_params_init();
advertising_init();

// Start execution.
application_timers_start();
advertising_start();

NVIC_EnableIRQ(UART0_IRQn);	
//NVIC_DisableIRQ(UART0_IRQn);	
for (;;)
{
		power_manage();
	  TaskGetDataFromPIC();
	  TaskAckPic();	
	

		
	}	

		
	}
