Hi, I am implementing HART protocol stack and need some clarifiction regard to inter-character gap timeout error. The document says that a gap error occurs if time between any two characters is more than 1 character time (i.e. 9.163 ms) but it does not defines any response to gap error.
I can think of two things one is to simly neglect this frame i.e. no response the other possibility is to respond with error frame. Which one is correct thing to do, please suggest.
