That must be it, mystery solved! Thanks for the insight.

What is going on here? I have an AdAFruit https://www.adafruit.com/product/284 hooked up to the Tx/Rx of my esp32-c3 module. Works great, all is fine at 115200 but when I upload a new code image (via the onboard USB JTAG, hooked directly to the D- D+) I get, well this: download_baud.png The code upl...

I am embarrassed to admit that I did swap them. The silly thing is of course I tried them both ways and somehow came to the conclusion it did not work in either configuration. I assume some other problem prevented me from seeing it work with the correct polarity. Once I discovered that everything st...

I'm working with an ESP32-C3 module (just the module) and dutifully wired up the D-/D+/GND to my PC and it does not recognize anything meaningful. It see's *something* and enumerates it as an "Unknown USB Device (Device Descriptor Request Failed)" but that's it. I can flash code to it as normal over...

perfect thank you this is just what I needed.

I have tried finding an answer to this question and my google-foo has let me down. I am creating a product I would like to automatically update an ESP32 using OTA. How does the Arduino IDE autodetect available esp32-OTA? I assume it has to do with subscribing to broadcast mDNS messages over the netw...
