ESP8266 not working
teo
Hello,my ESP8266 is somehow not sending back any data.I connnected it directly to the computer via TTL converter and when I power it on it sends a few random characters followed by "ready".Afterwards,it just echoes back whatever string I send it.I checked the pinout,everything looks perfectly fine.Likewise,if I change the baudrate to 76800 I am getting something readable at power-up.Down below I have attached what exactly is my terminal showing

2 years agoUnfortunately 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)

2 years agoHello,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.
