No, that is not what Sigurd said!

So that was just a quick summary - not the full details!

That's why I said earlier that you also need to follow his link for the full details!

Of course!

😃

Now you can verify the answer

I was confused about that:

is just need to change

"Update the Preprocessor Definitions by removing BOARD_PCA10056 and inserting BOARD_PCA10059"

But it is not!! :-)

I have checked the dongle pin numbers and realize that

RX pin is 8
TX pin is 6

After declaring them :-) it works

Thank you

That's why you get the error - you need to declare them before you can use them!

That's basic 'C' programming!

So, again, look at how & where they are declared in the unmodified example.

Then do the same in your modified example.

They are solely used in this function:

static void init_cli(void)
{
ret_code_t ret;
ret = bsp_cli_init(bsp_event_callback);
APP_ERROR_CHECK(ret);
nrf_drv_uart_config_t uart_config = NRF_DRV_UART_DEFAULT_CONFIG;
uart_config.pseltxd = TX_PIN_NUMBER;
uart_config.pselrxd = RX_PIN_NUMBER;
uart_config.hwfc = NRF_UART_HWFC_DISABLED;
ret = nrf_cli_init(&m_cli_uart, &uart_config, true, true, NRF_LOG_SEVERITY_INFO);
APP_ERROR_CHECK(ret);
ret = nrf_cli_start(&m_cli_uart);
APP_ERROR_CHECK(ret);
}

But not declared...

Good, so ...

The original project compilation goes well.

When I apply

"Update the Preprocessor Definitions by removing BOARD_PCA10056 and inserting BOARD_PCA10059"

and then compile it again the errors

‘TX_PIN_NUMBER’ undeclared (first use in this function); did you mean ‘P0_PIN_NUM’?
‘RX_PIN_NUMBER’ undeclared (first use in this function); did you mean ‘P0_PIN_NUM’?

appear

Did you follow the link which Sigurd posted for the full details of the modifications required:

[quote userid="81164" url="~/f/nordic-q-a/50524/usb-cdc-acm-example-and-tx_pin_number-error"]Please, could you guide me to solve these compiler errors[/quote]

The error tells you that those names are un-declared.

So the solution is to declare them!

I would suggest that you start by building the unmodified example, and then look at how & where they are declared in that.
