Thank you! I see my problem right now. Because i did modify the pin number on keil right at the pca10001.h file and i also use the nrf Uart apps on my cellphone to check the result. Maybe the apps on my cellphone just recognize pin #11. I mean i will check the nrf uart source code and modify pin on that one. Thank you again for fast response.

I don't understand what you are referring to about pin11 and why/what it's doing. If you are trying to reconfigure UART RXD pin from pin11 to pin13 you can do this easily by changing the UART_RXD pin setting in simple_uart.c or writing directly to the PSELRXD register. There's a definition for the pin in the code that you can easily change/modify to be pin13 if that's what you are trying to do.

I mean "Is there any pin replace that #11 pin?" If yes, how can i modify?

Do you mean that you fixed the issue?

We just find out the RX pin (11) is broken. We use pin 13 as the new one

Which camera you are using? Try plant uart receive interrupt and then try it. as simple_uart_get() may not hit on right time to get response from camera.
