One would need to compile their project with a version 1.63.3 or later and use that *.TFT file to upload their project to the newer Nextion device.

Since 2020, the newer Nextion devices may give a Data Error when trying to attempt loading a *.TFT file that was created with an Editor version prior to version 1.63.3 that does not have the ability to communicate with second source ICs.

As such, newer devices with secondary source ICs can not make use of elder versions of the Nextion Editor (such as v0.38, or LTS) before such firmware level code was incorporated into the Nextion Editor version firmware. This said, while elder devices only require firmware level code to communicate with primary sources ICs, the newer devices with secondary source ICs (visually identified with QR codes on the microSD slot) indeed require more recent versions of the Nextion Editor (v1.63.3 and later recommended) for the firmware to communicate with the secondary source ICs. The pandemic had created global supply shortages and to meet these challenges while keeping with Nextion quality then second source components/ICs were indeed needed. With the new, then there are indeed new behaviours and new possibilities. The Nextion Editor is not expected to retain every previous behaviours between versions exactly. As time has passed, many additional features and bug fixes were incorporated. Note: Nextion Editor has indeed evolved since its early beginnings, so I would like to take a moment for a quick review. So while we won’t be covering basics such as opening a file, we will point out somethings that might prove helpful to know, or reminders need be made. As such the GUI can be created within Hours instead of Weeks, and Days instead of Months. The Nextion Editor is used to rapidly create Human Machine Interface GUIs for Nextion HMI devices. This document goes through various features of the current Nextion Editor. Nextion Editor Guide Nextion Editor ico Introduction
