DFRobot Beetle Won't Write to Serial Monitor

Posted: April 14, 2024 | Categories: ESP32 ,  IoT

I'm working on a project that uses the Beetle ESP32 - C3 (RISC-V Core Development Board) and I noticed in my testing that the device wasn't sending any output to the Arduino IDE Serial Monitor.

I scratched my head for a while and couldn't figure it out. Right before I pulled out a different board I found a DFRobot Forum post Beetle ESP32-C6 Serial Monitor not working with the answer:

And always set the USB CDC as Enable

I also found this requirement in the wiki.

I had no idea what USB CDC was, so I had to look it up but when I checked in the IDE, that setting was disabled.

I enabled it, but then my Windows system started acting weird. I rebooted the system, fired up the IDE and everything worked as expected. Problem solved.

If this post helps you in some way, please consider buying me a coffee.
