Compatibility problems with Nextion Editor 1.61.1
Chronocento opened this issue · 10 comments
Dear Jevgeni,
hope you're enjoying summer, even in this difficult times given the COVID-19.
I'm here to bother you again because I noticed that your library appears to have some problems with the latest release of the Nextion Editor, version 1.61.1, whose changelog reads:
- New Audio* component (use internal resource or microSD)
- Add delimiter based split string instruction spstr
- Optimized Editor baudrate recognition
- Optimized escape character conflict in big5 encoding
- Optimizations for models T24, T28, T32 flash endurance
- Enhanced error checking for assignments where resource ID is invalid
- Optimized page swipe when changing pages
- Optimized get, print, prints and printh to single reply
- Optimized bkcmd handling
(Items marked with * are for Intelligent Series only)
I think the problem lies in point 8; I noticed it when I compiled my project with this latest version of the editor, and I got these errors upon connecting:
Command "get sleep" timeout.
Connection lost
I tried reverting back to version 1.60.1, recompile, and everything worked as before.
What do you think?
My bet it is 9. =)
@Chronocento Please set nextion logger to debug level and send me all that is logged from start.

The sequence, as you can see, repeats continuously
Yes, I understand the problem now and it is pain to fix... They go against their spec. https://nextion.tech/instruction-set/
When instruction successful they must send 01ffffff according to their spec when bkcmd is set to 3
Hah actually they added new table: Return Codes not affected by bkcmd value, valid in all cases
So get and sendme are exceptions now.
According to unit tests it should be fixed
Did this solve the problem?
Hi Jevgeni,
sorry for not having replied yet, I've been moved temporarily on other higher priority projects and I forgot to test and reply to you :(
I hope to try your new version next week, and report back here
Sorry for being late!
Just tested with a firmware compiled on Nextion Editor 1.61.1: works flawlessly! ;)
Then it was right decision to release 1.6.1 lib version.
