Serial port is not ready
Hi, I used ESP-Prog to connect the esp32 to the PC and when I click on the connect button the first time, this error pops out.
Then when I click again in the port dropdown menu it says (Paired), there is no error and I can use the tool. Any idea why? I guess the error pops out because of the pairing. It can be annoying because I need to click on connect button two times.
I'm having the same issue. Please let me know if you find a work around. Thanks!
Can you both please include the OS/Browser and exact device you're trying this with?
That error is shown when Improv is unable to open the connection to the serial port, for which it waits a second (src).
I'm using ESP32-WROVER-IE-N8R8, Ubuntu 20.04, Google Chrome v103.0.5060.134
Can you reproduce this with a different OS/Browser/Device. I am not seeing it on my end.
@tobiyas09, if it helps I instead just followed these instructions to flash directly.

Never tried to use ESP-Prog with esp-web-tools. It is uncommon since it is expensive in relationship to "normal" usb-serial converters (flashers). For reliable flash i can recommend the "golden" ch340 board. It has a 3.3V LDO chip which does power the esp chip reliable when flashing.
This is older now, but I am having the same issue; Windows with ESP32 board
Same issue on a Linux laptop and CP2104N tty converter.
Command line works fine with esptool.py.
