Reading file nrf_fprintf(line) ?

Question

Dear Members,

We tried reading file with nrf_fprintf()....

Code :

 NRF_LOG_RAW_INFO("Entries count _sd: %u\r\n", entries_count);
	  //printf("UART text \r\n");
		NRF_LOG_INFO("Reading file \r \n");
		f_open(&fil, "HRM.TXT", FA_READ);
									
								/* Read all lines and display it */
								while (f_gets(line, sizeof line, &fil))
							  
								 nrf_fprintf(line);
								 
										/* Close the file */
						
								NRF_LOG_INFO("Finished reading file.. \n \r\n");

								f_close(&fil);
}

Output in UART :

Does anyone know on how to rectify it ?

Kind regards..
