Hello, it's working now.

I missed a step for PCA10040e

#define NRF_LOG_DEFERRED 0

Thank you for your support.

Using the GPIO example, I have tried the below code using PCA10040e

And it works perfectly fine.

#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "nrf_gpio.h"

#define tx_pin 6
#define rx_pin 8

/**
 * @brief Function for application main entry.
 */
int main(void)
{
    /* Configure board. */
    //bsp_board_init(BSP_INIT_LEDS);
    nrf_gpio_cfg_output(rx_pin);
    nrf_gpio_cfg_output(tx_pin);

    /* Toggle LEDs. */
    while (true)
    {
        //for (int i = 0; i < LEDS_NUMBER; i++)
        //{
        //    bsp_board_led_invert(i);
        //    nrf_delay_ms(500);
        //}
        nrf_gpio_pin_set(rx_pin);
        nrf_gpio_pin_set(tx_pin);
        printf("ON \r\n");
        nrf_delay_ms(3000);

        nrf_gpio_pin_clear(rx_pin);
        nrf_gpio_pin_clear(tx_pin);
        printf("OFF \r\n");
        nrf_delay_ms(3000);
    }
}

I want to know how to read the output from UART (Rx Tx Pins), using a TTL converter (it doesn't work), or can I even use nRF52840DK to read UART output (SWD cable)?

For programming custom PCB, I'm only 4 pins (VCC, GND, SWDIO, SWDCLK).

When I connected the PCB with nRF52840DK, it still shows the UART output of DK, not from the PCB. What's the reason for that?

The project has BOARD_PCA10040 defined, and UART pins are typically then taken from the pca10040.h file

SDK_folder\components\boards\pca10040.h

Maybe you are using different pins on your custom board.

I have tried this project but still does not show anything on Serial Monitor. Could you please help with that?

Hi,

For the ble_app_template example we have pca10040e project.

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/ble_sdk_app_template.html

See this guide on how to transfer a PCA10040e project to nRF52810 hardware:
