I bought an esp8266 01 board and tried to upload some codes on it (email sending and blink...) but I couldn't make them work.
AT commands don't even work.
I tried to install the Espressif firmware. It starts Sync and after some time it changes to Fail. I also tried Erase but same thing. So did I damage the already installed firmware? Can i continue using the board?
Is the board already damaged and how can I know? And to make sure, Rx is connected To Rx and Tx to Tx or Rx to Tx and Tx to Rx? So if anyone knows a good tutorial or can help please let me know.
