ESP8266 Community Forum

- Wed Jan 13, 2021 8:49 am #90183 I have been working with ESP-01 for a while. I want to communicate with AT commands. But I am constantly encountering a problem. After starting to work with ESP8266 it is constantly resetting. The last time I worked with the ESP8266, I gave 5V but stopped the supply before the module got too hot. But when I looked at the serial port screen, esp8266 I saw that print reset so I updated the firmware. but I see information like below on the serial port screen. . I have tried all the update files available on ESPRESSIF's site, but I am not successful on any of them.and i tried all baudrate speeds.Please help me. THANK YOU.

They are really cheap. Throw it away and use a new one.

This is the ESP8266 Arduino forum: you might want to use a different, better suited, forum instead.
(FYI very few of us use AT, so your question might remain unanswered)

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
