UART not working with ble_app_hrs_c

[Juan Gomez]

Hello Nordic Team!

I'm working with the ble_app_hrs_c and a UART code I developed following the peripheral/uart example. 

On the peripheral/uart example we have the following includes:

#include "app_uart.h"
#include "app_error.h"
#include "nrf_delay.h"
#include "nrf.h"
#include "bsp.h"

When I "copy/paste" these includes on the ble_app_hrs_c and build it, it says "app_uart.h no such file or directory".

I know this is due to ble_app_hrs_c not using these files, but since I used the peripheral/uart example as base code, I don't know how to add them ;) 

I really appreciate all your help and thanks in advance!

Hi Marte, thanks a lot for your answer!

I changed the NRF_LOG_BACKEND_UART_TX_PIN to 0 but didn't work :( 

My main code, the other code is the same as in the examples from Nordic

int main(void)
{
    bool erase_bonds;

    // Initialize.
    log_init();
    timer_init();
    power_management_init();
    buttons_leds_init(&erase_bonds);
    ble_stack_init();
    gatt_init();
    peer_manager_init();
    db_discovery_init();
    hrs_c_init();
    bas_c_init();
    scan_init();

    //uart code
    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
  };  
  
    uint32_t err_code;

    APP_UART_FIFO_INIT(&com_params, UART_RX_BUFF_SIZE, UART_RX_BUFF_SIZE, uart_err_handler, APP_IRQ_PRIORITY_LOWEST, err_code);
    
    APP_ERROR_CHECK(err_code);
    
    
    //Start execution.
 
  while(true){
    
    uint8_t cr;

    while(app_uart_get(&cr) != NRF_SUCCESS){
      
      if(cr == '1'){
        printf("connected");
        scanning_start(&erase_bonds);

        for (;;){
        idle_state_handle();
          }
      }

      else if(cr == '2'){
        
        bsp_board_leds_off();
        printf("Off");

      }
      else if(cr == '3'){
        
        bsp_board_leds_on();
        printf("32");
      }
      else if(cr == '4'){
        
        bsp_board_leds_off();
        printf((uint8_t*)"OTA");
      }

      cr = 0;
    }
  }

}

I tested my uart code both before and after the //initialize. If I use j-link to download the code, it won't work, and if I use debug mode, it prints to the debug console from SES.

I tend to think is something in the sdk.h, but don't know where to look.

Thanks a lot for the help!
