I've been throught the tests with TWO displays.
- ORIGINAL 2.4" K Series bought from ITEAD
- CLONE 2.4" T Series bought from Aliexpress seller
Both them have previously worked fine with Editor also on the Dual Hotspot.
Both them got the FW updated while loadind the schema with 0.58 to S131.
Both them showed the same behave on the HS.
(This is, like they were NOT plugged to the modem port on the MMDVM board).
Now I've done "step back" to Nextion LTS software (0.53) and reloaded to both them the schemas.
(I had a copy on HMI files done, as they do not accept to "go to old version")
Both have worked properly on tests and I keep the T series working on the HS.
BTW, when I loaded the schemas on them by using LTS version, FW was "re-updated" to S99 (downgraded in fact)
If you want the HMI files, just let me know...
Could it be some kind of issue affecting only me?.... Maybe yes, maybe not.
This is why I said: "My Experience".
