What is "can't connect, no HF2 nor JDUSB" and how to handle it
Hello?
I have a question because I've been trying to do something with devicescript, but it's not working properly.
I failed to establish a serial connection to "ESP32-C3" board with an error message "can't connect, no HF2 nor JDUSB"
I'm not actually someone who works with devices professionally. I just wanted to try it out as a hobby. Instead of writing in C code, it seems that using TypeScript is an easier approach, so I wanted to give devicescript a try.
Therefore, I find it difficult to understand the meaning of that message and also uncertain about what steps to take next to resolve the issue.
An I also looked at the troubleshooting section in this link, but I couldn't understand at all.
If you could give me a rough idea of what steps I should take, I'll do my best to follow them.
If there's any way I can contribute to resolving the issue, please let me know, and I'll be happy to help.
Environment
I am a macOS user. (Ventura, Apple M1 Pro)
The board I have is "ESP32-C3-DevKitC-02" as shown in the image below. it belongs to the ESP32-C3 series.
I can supply power through USB and establish serial communication by connecting to the UART, as shown below.
Just in case it might work, I also tried connecting it as shown in the picture below.
What I have tried
I used the Arduino IDE to flash and run ESP32 example code on the board (It worked.)
The board doesn't match exactly, but I selected Espressif ESP32-C3 (bare) and also tried flashing it.
However, when attempting to establish a serial connection, it doesn't work.
