@py: Are you using Hardware Flow Control(HWFC)?

Yes, Bjorn answer below was correct. I had to change some pin defines.

Hi I have exactly the same problem and I have already set my UART pins. Did you solve this issue ? (I am also using a NRF52832 with the same SD and bootloader example, everything works well with the DK but I have no answer from the TX pin of my custom board)

You have to edit the following defines in hci_transport_config.h

#define HCI_SLIP_UART_RX_PIN_NUMBER  RX_PIN_NUMBER                
#define HCI_SLIP_UART_TX_PIN_NUMBER  TX_PIN_NUMBER                      
#define HCI_SLIP_UART_RTS_PIN_NUMBER RTS_PIN_NUMBER                     
#define HCI_SLIP_UART_CTS_PIN_NUMBER CTS_PIN_NUMBER

The pin numbers (RX_PIN_NUMBER, TX_PIN_NUMBER, RTS_PIN_NUMBER and CTS_PIN_NUMBER) are defined in pca10040.h, since your're using a custom board you should define a custom header, custom.h to hold the pin configuration for your board.

Best regards
