How to send sensor data using AT commands to a device using Uart in segger embedded studio

[Rajbir Singh]

Hi, I am new to NRF and segger embedded studio.

So I want to send temperature sensor data connected with nrf52840 DK to the Murata1_SC  device using UART.

The data will be sent using AT Commands.

So how to send AT Commands in Segger embedded studio.

Thank you for the help in advance.

I have tested uart example, but i don't know how to send commands

Here is my code

#include <stdbool.h>
#include <stdint.h>
#include <stdio.h>
#include "app_uart.h"
#include "app_error.h"
#include "nrf_delay.h"
#include "nrf.h"
#include "bsp.h"
#include "nrf_uart.h"

#define UART_TX_BUFF_SIZE 128
#define UART_RX_BUFF_SIZE 128

#define UART_HWFC APP_UART_FLOW_CONTROL_DISABLED

void uart_err_handle(app_uart_evt_type_t * p)
{

}

int main(void)
{
uint32_t err_code;

bsp_board_init(BSP_INIT_LEDS);

const app_uart_comm_params_t com_params =
{
RX_PIN_NUMBER,
TX_PIN_NUMBER,
RTS_PIN_NUMBER,
CTS_PIN_NUMBER,
UART_HWFC,
false,
NRF_UART_BAUDRATE_115200
};

APP_UART_FIFO_INIT(&com_params, UART_RX_BUFF_SIZE, UART_TX_BUFF_SIZE, uart_err_handle, APP_IRQ_PRIORITY_LOWEST, err_code);

APP_ERROR_CHECK(err_code);

printf("Hello PC from Nordic Device!!!\r\n");

while(true)
{
uint8_t cr;

while(app_uart_get(&cr) != NRF_SUCCESS);//wait here for the character from pc
if(cr == 'o')
{
bsp_board_leds_on();
printf("Leds are ON\r\n");
}
if(cr == 'f')
{
bsp_board_leds_off();
printf("Leds are OFF\r\n");
}
}
}
