printf doesn't work when implemented in a function.

[Sylvain]

Hello,

In one of my codes, I use the printf function. It works properly when implemented in the int main(void), but when I try to use it in a static void NAME (void){} function the printf don't print anything over the uart.

Are there any know behaviours about this ?

Config : Segger Embedded Studio, SDKs v15.0, Windows 10, PCA10056 0.12.0 2018.9

Best regards,

I managed to make it work. Try following these steps: 

• Open the template project template_pca10056 in SDK v15.2.0
•  Modify your main.c to the following:

#include <stdbool.h>
#include <stdint.h>

#include "nrf.h"
#include "nordic_common.h"
#include "boards.h"

static void awesome_function (void){
      printf("From function \r\n");
}


/**
 * @brief Function for application main entry.
 */
int main(void)
{
    printf("From main \r\n");
    awesome_function();
    while (true)
    {
        // Do nothing.
    }
}

I guess the problem is something else. If you upload your code I might be able to figure it out.

Best regards, Simon

I have posted the code in which I try to use the printf command. In fact, this is in the discovery handle function. When the service has been discovered.

I am not sure why the printf() command doesn't work. If you would like to upload your project in zipped format, I could take a closer look at it.
