Hi, I have been trying to save few data on a json file that I created in the application. 
But I found out that the <stdio.h> did not contain fopen function.
1) How can I open a file before storing data in that file?
2) Is it possible to send a .json file through UART?
Please let me know if there are any other method to store data in json file if this doesn't work.
Thank you.
