Hello,
Initially, everything was perfect. I managed to upload the setup file successfully.
However, I am now faced with an error while trying to upload a new setup: "Connection Failed!" The USB-to-TTL module is connected to a Nextion Discovery NX3224F028 2.8" Resistive Touch Display. When I try to upload the file through the Nextion Editor, it reports "Connection Failed, Forced Interrupt." So far, I have tried solving the problem by using various USB to TTL modules.
Does anyone have any input that may help?
Connection failed in "Nextion Discovery NX3224F028 2.8" Resistive Touch Display"
1.Upload the blank TFT file (only with a blank screen) for the program to release the RX and TX ports. Then use a MicroSD to upload the blank program and check if it is uploaded or not
2. If not works then try a different method to upload. Using the simhub version of the Nextion Editor software, click on 'File' on the top left and select 'TFT File Output'. This will prepare the file for upload using the simhub file format. Double click on the generated file in the folder shown and a pop-up window will appear. Select the correct port then baudrate and begin the upload.
