Hello together, I hope somebody can help me.
I have project, for which I use an ESP32. After I experimented with the hardware, I think I might have shortened something. After that I tried to reupload the code but I got the error: "A fatal error occurred: Failed to connect to ESP32: No serial data received." I thought I might have burnt out the ESP32, so I tried it with another one I have. But with the other chip I now get the same error. Note that I did not do anything with this chip, I got that error without connecting it to anything.
I tried using a different PC, different cable, different USB Port, holding down the BOOT button while uploading, nothing works.I tried hard resetting the ESP32 with the python esptools, but even cmd throws the same error.
I checked the device manager, it recognizes the chip on the Serial Port and Arduino IDE shows that it is connected.
In other discussions, people said they needed drivers for the connection module or had to wire it differently, but I am using a Dev Module which is directly connected via USB, so this is no option. What else can I do? I hope somebody has a solution.
Was your ESP connected to your computer when this happened?
If this is true I will take a SWAG and say you may have damaged your computer. Try to completely power it down, go have a cup of whatever, take your time then reconnect and see if it is back.
If that does not fix it post an annotated schematic showing exactly how it was wired when it failed.
It was not connected. And as I said, I tried it with another computer which was newly set up.
