Hi everyone 

I want to sperate array data. For example phone send sifre[4] = {0x00, 0x01, 0x02, 0x03} and seperate my board

static const uint16_t sifre[4] = {0x00, 0x01, 0x02, 0x03};

if(led_state == sifre[4])

bsp_board_led_on(LED_2)

static const uint16_t sifre[4] = {0x00, 0x01, 0x02, 0x03};
if(led_state == sifre[4])
bsp_board_led_on(LED_2)

how can i do it?

This doesn't make much sense. 

Do you actually want to check led_state against your sifre array? Where does the data array come from? What kind of data type is led_state? If by data[4] you mean sifre[4], then sifre[4] is outside your data array's boundaries. You need to check sifre[3] to get the fourth byte in the array.

Thanks Martin,

I want to send a password to the development card from the mobile phone. for example, "1,2,3,4" if the incoming "1,2,3,4" is led_state on. how can i do it?

If you simply want to compare two arrays you can do it like suggested here for example: C program to compare two arrays.

bool compareArray(uint8_t a[], uint8_t b[], uint8_t size)

{

for(uint8_t i = 0; i < size; i++)

{

if(a[i]!=b[i])

{

return false;

}

}

return true;

}
