Hello,
I used to be able to upload TFTs to my NSpanels using ESPNexUpload, but the uploads now hang at the start. However, errors are detected correctly.
So I tried to use direct serial uploading from the editor, but the panel sits in a boot-loop, I guess caused by the ESP32 and powering the 0v/5v pins directly.
My standard Nextion uploads correctly using both methods, and the same ESP32 code.
** SOLVED **
The RX/TX pins are hard-coded in ESPNexUpload.cpp
The NSpanel reverses the pins. (Thanks a bunch Sonoff)
