Could not open port 'COMx':Permission Error13

1

Hello,
I bought a development board IoT ESP8266 Lua NodeMcu V3 WIFI ver 0.1 modul, installed the drivers from sestavení - postav si svůj vlastní senzor vzduchu 💨 and i can’t flash the firmware.

The utility displays an error: Cannot configgure port, something went wrong. Original message: PermissionError (13, None, 5)

I connected the board using the Arduino IDE:

esp_air

I tried two USB cables on two devices, the situation is the same. Does anyone have a solution to this problem?

Thank you

OS: Windows 11 22H2
airRohr firmware flasher: 0.3.2 x64
Arduino IDE: 2.0.4

Try these drivers: http://www.wch.cn/downloads/file/5.html
But I am not sure they work for WIndows 11.

Hi, just making sure - are you flashing with all the cables (SDS011 and BME280) disconnected? Just the plain board?

Unfortunately, the situation is the same

Yes, of course. Flash only board.

I found a tutorial from user pjg. It looks like this tutorial managed to upload the firmware.
