I have a brand new original (from Arduino.cc) Nano ESP32 and I cannot seem to repeatably flash any code compiled to it from the latest Arduino IDE (2.3.3). I have the Arduino ESP32 Boards(2.0.18) and esp32 (3.0.7) installed. I have tried changing many USB cables. Connecting it to the laptops USB A and C ports. (The cables can be used to read hard disks). In the device manager, I can see COM6 pop up as soon as I connect the nano under Ports (COM & LPT) but it has no device description. I sometimes get No DFU capable USB device available error.
In the "Select Other Board and Port" section, I can see "Arduino Nano ESP32" and "Arduino Nano ESP32 - esp32" both. Both dont work.
Any ideas?
I don't know if it 'ruins' anything, but you should only select the Arduino Nano ESP32 for Uploading with (not the other).
Reset the Arduino bootloader on the Nano ESP32 – Arduino Help Center
Ok so this link https://support.arduino.cc/hc/en-us/articles/9810414060188-Reset-the-Arduino-bootloader-on-the-Nano-ESP32 works for me. I followed setting the nano by connecting the B1 and GND pins and pressing RST etc. Was repeatably able to flash the Blink code.
Thanks!!
Now on to the next problem
