Bluetooth module HC-05 does not issue AT commands and it is impossible to flash it. There is no programmer, so Arduini Uno is used, how to flash it?

Question

Arduino

It is not possible to flash the HC-05 module, we tried different methods. But something goes wrong, it is displayed in the device manager, but the commands are not displayed in the terminal or in the port monitor.

Apply 3.3V to the KEY contact of the module (or pin 34 of the board).
