In the "ble_app_uart" in the ble_peripheral showing the error?

error is -

Compiling ‘retarget.c’
unknown type name '__printf_tag_ptr'

Please tell me solution for it.

which version of segger embedded studio are you using? 

I haveProgram Files\SEGGER\SEGGER Embedded Studio for ARM 5.62\include\stdio.h

and I see that member declared here.stdio.h

segger embedded studio - 6.30 V

You are right, this file (retarget.c) is broken with the latest SES. You might have to use the older version of the SES for this to work.

I have put the definition for __printf_tag_ptr in stdio.h. This solved my problem.
// Macro version of putchar.
#ifndef __PRINTF_TAG_PTR_DEFINED
#define __PRINTF_TAG_PTR_DEFINED
typedef struct __printf_tag *__printf_tag_ptr;
#endif
int __putchar(int, __printf_tag_ptr);
