ok i checked pca10028 pins RX->11, TX->9, CTS->10, RTS->8 and my nrf51822custom board (includes lis3dh accelerometer communicates with I2C), I2C_SDA_PIN ->11, LIS_3_INTERRUPT_PIN->9 are assigned and pin 10, pin 8 are not connected. Ok, i will use usb to ttl serial converter (it does not have RTS CTS) and try to solder them.

HWFC is used.

Can you connect the pins to UART externally ? If your original UART pins aren't overlap the LEDs pin on the nRF5DK, you don't even need to disconnect them I think.

There is no option to re-configure the pins.

Hi Hung; thank you for your support. Unfortunately there is not any pin matched with development board. i thought that solution but i could not implemented because of QFN package limitations. i wonder that whether there is any hidden configuration with nrf sniffer. Does nrf sniffer use RTS CTS pins (hardware flow control pins) ?

Hi,

Yes it should be possible. You just need to match the UART pins on your board with the UART pins on our nRF51 DK.
