All the work is done and The project is finally ready to show in the college.Though It is not the complete project but at least I will be able to show it to them.  I have some screenshots and sir gave me diferent modules of the project which have lwip and mbedtls integrated into the code. Though it cant connect to the serve but some outputs are shown.

working on them.

Today sir helped me in debugging and there were quite a few things which were unanswered, so we found some errors which were earlier unnoticed.

lets see if working on them would solve our issue or not.

both our ways of setting up the things didn't work right so  now we were back on debugging code. Where are the declarations or definitions for different functions. 

This way also didn't give the output that we wanted. So we tried the same method on a windows server as its commands would be easier because we work mostly on it. But this method also didnt work. 

A linux server was set up today and server certficate and key were generated for connecting to it. The board which we are using is termed as a client, it has the server key and certificate in place. and client key and client certificate generated into it. 

Today we tried to connect to nghttp website directly, but it was not able to connect on the specified port. So we tried to set up a linux server on remote basis and when it will be made it will connect to the nghttp.

After tracing the output backwards, for hours there was no precise error that could be said to be the cause bcz of which the code dosent work but lets see may be the small errors that we found are the main cause of wrong output.

and i was on it only. tracing the output backwards.

today it showed output which was intended to be the correct output but i had to go through all the output what functions it was calling and all so debugging all of it and seeing what functions were being called and it was a very complex part as inside a function there were more functions and more conditions and inside them there were again more functions.
