Nextion 3.5 RPi3 Still No Input

I finally managed to get the nextion to get past the "connecting to printer.." screen and display the home screen. The IP address does not show up and none of the buttons work. I have yet to get ttyAMA0 to work, so I am using ttyUSB0. ErrorOutput.log complained about no pushbullet API key, but I plugged 123456 into config.json and it at least quit complaining about it. It appears as though ip and all the other necessary node modules are installed properly. Config.json still defaulted to ttyAMA0, but I changed it to ttyUSB0 and if I "tail -f output.log", I get repeated "error opening port  /dev/ttyUSB0 retry in 2 seconds" errors and a list of all available USB serial ports.

TtyUSB0 is obviously working because I am getting display. Where to look next??

Are you using Nextion internal support? pushbullet api is not needed probably you are using old custom installations of nanodlp.

Also, I have tried this several times using tutorials found here and elsewhere: https://www.nanodlp.com/forum/viewtopic.php?id=710

I can get back to the same spot, display but no touchscreen control, repeatedly, install after install.

You do not need tibus, remove it. Just install TFT on your HMI and setup correct path on nanodlp for nextion.

Just delete the nextion folder?

Nevermind, I got it. There's a lot of bad information out there. Tibus should take his tutorial down.
