#52673 hi, I manage to test a blink example using this guide http://www.arduinesp.com/blink

It works ok with one module, but with other I got this error when uploading the same scketch

Code: Select allerror: failed reading byte
warning: espcomm_send_command: cant receive slip payload data


There is any way to check if the module is defective or it's missing bootloader?
