There was a problem with the flashing of the module. After spending 5 hours searching, I realized that I had to press the ＜FLASH> button, then immediately the <RESET> button. Parameters for flashing: baudrate 115200; Flash speed 40MHz; SPI Mode DIO. I think you can indicate this in the advertising booklet. I think this can help many people to run away from the problems that I encountered.
