Unfortunately the website sends me an error when I want to edit the topic question.I will write down over here what is the chip sending at 76800 bd(given the fact that it is connected directly to CH340 converter to my pc)

Hello,no,if I send AT command I am getting AT on the RX line as an echo.Whatver existing string I would send it the ESP chip would send it back the same way(instantly).I will add another image in which shows off what the ESP is sending at power-up with a baud rate of 76800.

Hi,
when you send AT, are you getting OK?
