not advertising after uart pin change

[researcher]

Hi, 

i have changed uart pins to second port. After that it is not advertising. when i connect the FTDI converter to the uart pads from custom board, it starts working and advertising. If i remove the uart  to usb converter, it will revert back to not advertising.

Here it is the change in code, 

in pca10056.h

#define RX_PIN_NUMBER NRF_GPIO_PIN_MAP(1,8)
#define TX_PIN_NUMBER NRF_GPIO_PIN_MAP(1,6)
#define CTS_PIN_NUMBER NRF_GPIO_PIN_MAP(1,7)
#define RTS_PIN_NUMBER NRF_GPIO_PIN_MAP(1,5)

is there any dependency on port changing?

Assuming that you are using the nRF52840-DK.

Can you switch off the logging  in the application to see, if the act of sending the data to the unconnected UART results in the buffers getting full, and triggering a stop condition in the application. Verify the switching off of the UART logs on the connected UART and then switch to the unconnected UART.
