does macro OC_TCP work?

[ustccw]

Hi,
i notice that the macro OC_TCP defined in repo, and works on CoAP procotol.
A: if enable OC_TCP, does that mean CoAP would based on TCP rather than UDP?
B: does that work well now if enable OC_TCP?

thanks in advance.

A: It does not mean that TCP is preferred. It is transmitted according to each type.
B: Yes, it works well. Please let me know if there is a problem.
