ESP8266-01 is not working and it cpu gets hot
Posted: Fri Jun 21, 2019 10:05 amit has been so long since I tried to connect the esp8266 through Arduino Uno and get it to work my goal is to send data from the Arduino Uno to web site, I have tried everything and a lot of codes but none worked at first I could get a response but sometimes it does and sometimes it does not I even bought an other one but the new one did not respond at all so I flashed the old one following the instructions in http://remotexy.com/en/help/esp8266-firmware-update/ and I got response the next day I tried to reuse it and it does not respond at all not even when I put the serial on 115200 and both NR&CR and tried AT but nothing showed in return .i found this tutorial
and I tried to get it to work using a mobile app but as usual, it does not work
AT

this is the code
i wired it like this
one last thing is it gets hot every time so what could be the problem what's wrong with is what should I do

i wired it like this
Code: Select all
RX -> RX /TX-> TX/ CH_en and vcc to 3.3 v of the arduino / gnd ->gnd
one last thing is it gets hot every time so what could be the problem what's wrong with is what should I do
