We are a small company that has been working with Nextion displays quite extensively for our projects for the past one year and we have sold more than 30 displays which worked flawlessly until recently!
We pushed out an update recently with fresh compiled TFTs and since then all our displays have stopped responding to hardware! Compiling previous versions which were deployed aren’t working as well!
We suspected the new update 1.63.1 and 1.62.1 but compiling with 1.61.1 after uninstalling the updates haven’t helped as well! We have fresh stock of 4 displays with us and neither respond to our arduino based hardware however connecting the same microcontroller board to nextion debugger works flawlessly! The debugger responds correctly.
We have enough experience with the displays and we have checked baudrates / serial ports etc so that’s not the problem for sure.
Nextion debugger + our card = works
Nextion Display + our card = used to work 2 weeks ago, doesn’t anymore
Any idea what’s going on? Any work around?
