Not to drift off the OP, but I am very curious, are the slaves running at 19200 and 115200 on the same RS-485 network? If so, How do the slaves at 19200 understand the telegram transmitted at 115200 is not for them? How do the slaves at 115200 understand the telegram transmitted at 19200?
Hey. I found the reason for this phenomenon, it was in the uart-ttl converter, I bought the second version of this module, and my sketch curve, it worked perfectly) Thank you very much for the help)
