Forget it, I duplicated rungs and forgot to rename my TOFs appropriately. I did do something stupided.

Nextion Enhanced HMI Solved (by Tom J.)
In this post I'm going to focus on sending and receiving serial data uart with the HMI. Enclosed in this zip file you will find a ladder and the HMI file to be used with the Nextion software.
The big hurdle was the stop bits And as it turns out sending those stop bits as hex was the problem.
There is a special character that needs to be used in place of 0xFF that can be obtained with a keyboard combination of ALT+0255 that must be used as the spot bits.
The ladder file is pretty well commented but I kind of jumped the gun on the HMI file and didn't do any commenting in there, fortunately the HMI file is pretty simple to understand as it sits.
