I am trying to re-connect to an AZDelivery ESP32 board that I haven’t used for a while through ESPHome Builder but am struggling; I have downloaded and installed the correct CP2102 driver as I now have a new laptop, but when I click on Connect it tries to do so but never succeeds, with a continued revolving “wheel”. I am using a “data” USB cable (I wasn’t before!), the ESP32 is double flashing red.
As a last resort I tried to Add a Device instead, but again, all I get is a continual revolving wheel. So it seems that my laptop & ESPHome Builder can “see” the CP2012 USB to UART Bridge Controller, but not the ESP32 board itself.
Windows you likely need to load the driver for the serial chip you are trying to talk to. You MUST use edge or chrome, no other browsers will likely work.
If you are using Linux, does the user trying to flash it have permission for dialout? Also you have to use chrome.
If you try to load something and it can’t talk to the chip, the pop-up (unless you have it blocked) tells you all this.
Thanks both, I think it was solved by pressing the boot button during Connecting, but whatever it was I have now managed to get it working again. So thank you very much!
