How to write a byte in flash by using

static void flash_word_write(uint32_t * p_address, uint32_t value) function

while in a advertising mode.

I tried to call the function . It's stuck .

Which SDK and SoftDevice version are you using? flash_word_write() typically tries to access the NVMC registers directly, but you shouldn't do that if you are running a SoftDevice. Then you should be using sd_flash_write() and sd_flash_page_erase(), see this for more information.
