Nextion screens send two messages during startup:
00 00 00 ff ff ff when it boots and
88 ff ff ff once it‘s ready.
Do TJC screens - especially the X5 series - behave in the same way? Their documentation seems to only mention the second of both messages.
Background is that my code uses both messages to detect a nextion screen and in the case of one user it seems to fail to detect its TJC X5 screen (TJC editor v1.63.1 - as of now the most recent version).
