- Tue Nov 29, 2016 12:45 pm #58853 Many things can cause this....

1. Wrong serial port
2. Wrong serial speeds (115200 recommended to start)
3. Bad power supplies
4. Bad connections including grounds....
5. Wrong chip connected....
6. ESP8266 not in bootloader mode due to I/O pin issues

You need to carefully check these.
