Hello everyone,
I've bought a Lilygo ESP32 T4 1.3 for experimenting (I have no experience programming at all) and I was happy to find this video Getting Started with Lilygo T4 with Arduino IDE | ESP32 | ILI9341 LCD Display | - YouTube
I did everything exactly like explained in the video, however when I want to upload the sample code to the board I get the error message ''A fatal error occurred: Failed to connect to ESP32: No serial data received.'' and ''exit status 2'', the display on the board just shows a list of nearby internet networks and when I press the left button it says ''buzzer test'' , when I press the second button it says ''Scan network'' and goes back to showing the network list. Third button appears to be doing nothing.
I know it's naiv of me to think I can do anything with this as a complete rookie, but I would like to understand how this is already failing when I'm just trying to set the board up.
Other topics on this forum regarding this error message have not helped me either.
Could it be that my mini-USB cable has bad quality?
If anyone could say something useful, I would be so thankful. But to anyone else, thank you for your time reading this also.
Very few people are going to watch a Youtube video showing what someone else did when it's you that has the problem. Whatever it is that you've done wrong won't be found in the video. After all, they got it to work, correct?
You haven't shown the sketch that you used, properly enclosed with the <CODE/> tool.
You haven't shown a schematic of how you wired things up.
You haven't shown clear, well lit, in focus pictures of your actual wiring.
Reading How to get the best out of this forum will provide you with excellent advice on the proper way to provide the information necessary for someone to attempt to help you in resolving your problem.
There are two types of usb cables. Some are power only designed for charging, and others have power as well as all the data lines. You may indeed have the power only cable, and that would result in the error you are seeing.
Given that the OP seems to have both uploaded a sketch and gotten it working (display and buttons are doing things) and not been able to upload a sketch (failed to connect), I admit I'm at a loss to understand as to how a power only USB cable could be responsible.
