What "should be DK" exactly? When making a project for a custom board, it's recommended to create a board .h file of your own called whatever you'd like it to. You can use the pca10040.h as a reference, but you should edit all pin configs/defines that doesn't do the same thing as the DK to do what your board does.

If the only change you require is to change the pins that the UART uses you can switch out RX_PIN_NUMBER, TX_PIN_NUMBER, RTS_PIN_NUMBER and CTS_PIN_NUMBER to the pin numbers you'd like them to be, and that should be sufficient to let your custom board communicate over UART with your desired GPIOs.

Best regards,

Simon

I simply need the code which will allow the EUTto communicate via different GPIO"S

Not sure what do you mean by that i am using PCA10040

it shuold be DK

Have you checked out the ble_app_uart example project where the uart_init() function initializes all four UART pins. Then you can set these to what ever pin numbers you'd like.

static void uart_init(void)

{

    uint32_t                     err_code;

    app_uart_comm_params_t const comm_params =

    {

        .rx_pin_no    = RX_PIN_NUMBER,

        .tx_pin_no    = TX_PIN_NUMBER,

        .rts_pin_no   = RTS_PIN_NUMBER,

        .cts_pin_no   = CTS_PIN_NUMBER,

        .flow_control = APP_UART_FLOW_CONTROL_DISABLED,

        .use_parity   = false,

#if defined (UART_PRESENT)

        .baud_rate    = NRF_UART_BAUDRATE_115200

#else

        .baud_rate    = NRF_UARTE_BAUDRATE_115200

#endif

    };



    APP_UART_FIFO_INIT(&comm_params,

                       UART_RX_BUF_SIZE,

                       UART_TX_BUF_SIZE,

                       uart_event_handle,

                       APP_IRQ_PRIORITY_LOWEST,

                       err_code);

    APP_ERROR_CHECK(err_code);

}

What SDK are you using for development, the nRF5 SDK or nRF Connect SDK? You need to create a custom board file for your project when creating an application for a custom board.

Best regards,

Simon

Well this is not good enough as this is Only UART pins,I got inputs that pins are defined in h file

and also need to define ALL the 4 pins required not only rx tx

RE: Radio test example - UART pins

user91187 — Thu, 28 Apr 2022 12:24:06 GMT

In the nRF5 SDK v17.1.0 that you presume you have downloaded, you will find the pin number as defined like the picture above.

You can change the "TX_PIN_NUMBER" and "RX_PIN_NUMBER" to the pins you need to use in your layout. You only need to edit the two instances to P0.06 and P0.08

Jonathan

on top of this regard doing it using segger is there a clear application note , as the ticket is not clear...

RX TX testing is mandatory for regulation purposes... and guidance is required to be provided to the lab.

Simply need clear and simple instructions ....which are working...

RE: Radio test example - UART pins

user64407 — Fri, 22 Apr 2022 04:16:05 GMT

the issue is not on SDK side but on the eut side...

as they need to be connected SDK is host and eut is client..

i don't have all the pins available in my device

I have opened radio test example but i couldn't find pin numbers in the code...

i simply need the location of the pins definition and the relevant code version

RE: Radio test example - UART pins

user91187 — Thu, 21 Apr 2022 15:00:39 GMT

You are using the nrf52832 WLCSP, and you want to use P0.07, P0.08, P0.05 and P0.06 as the UART pins ?

Are you more familiar with the nRF5 SDK or the nRF Connect SDK ?

In the nRF5SDK you can do it in the main file, if you build for the PCA10040 it will be for the 52832.

In nRF Connect SDK you have to create a overlay file for the new pins you want to use.

See example in this devzone ticket,

&uart0 {
compatible = "nordic,nrf-uart";
status = "okay";
current-speed = <115200>;
tx-pin = <6>;
rx-pin = <8>;
/delete-property/ rts-pin;
/delete-property/ cts-pin;
};

Here is a link to zephyr overlay, Devicetree HOWTOs — Zephyr Project Documentation

Jonathan

actually, the difficulty is how to redefine the pins..... as it is not clear from the example..

regard sdk in the website only version 17 is available for download

Hi,

You can use the radio test example with other GPIO's, so if you are using other pins that is OK.

RTT/SWD interface can also be used.

It should be possible to do it "over the air" but we dont have an example on that. Her is an older case disusing it: (+) Radio Test Example using SeggerRTT? - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)
