Hi,
As the subject description, I just remove the part of hid function from main.c then make the personal source file.
Before I removed, the project could work as usual.
And after I create the source file for hid function into the project, the project could be built without error.
Somehow, it could not work properly.
As you could see from the picture above, the left show fatal error compare to the right(Normal).
Not sure why it could be connected but show pair immediately without function.
Do you have any idea or instruction could share with me?
Thanks.
