[ps_anu]

Hi folks,

I am working on ble_app_uart example program nRF52 SDK 15.2 Verion , in this case i am writing the data in flash for future use , Now i am to get the specific  data from flash, how to do that? 

guide me

char *name[80]="hello";
  char newname[80];
    rc = nrf_fstorage_write(&fstorage, 0x3f000, name, sizeof(name), NULL);
    APP_ERROR_CHECK(rc);
    
      printf("Write data \"%s\" to flash.\n", name);


 
    rc = nrf_fstorage_read(&fstorage, 0x3f000,&newname, sizeof(newname));
    APP_ERROR_CHECK(rc);
  printf("read data \"%s\" to flash.\n", &newname);

    wait_for_flash_ready(&fstorage);

In this above case, i can't able to print the read data , tell me if  i have done any mistake. my code is correct or not

Hi

Are you able to see any output at all on the terminal you're printing to? Is the problem that you're trying to print a string when name and newname are characters and not strings? You can add a loop to see if the operations succeed as well using an if loop like this, so that the application only prints if the operation was a success, and handles the error/ prints the error code if not.

if (rc == NRF_SUCCESS)
{
    /* The operation was accepted.
       Print your data            */
    
}
else
{
    /* Handle error.*/
}

Best regards,

Simon
