Arduino Mega with ESP8266

[carlosrodriguesIT]

After I modified the header file mention that work with MEGA2560, i still cannot upload my sketch to ESP8266, look the error:

trying to connect
flush start
setting serial port timeouts to 1 ms
setting serial port timeouts to 1000 ms
flush complete
espcomm_send_command: sending command header
espcomm_send_command: sending command payload
read 0, requested 1
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed

Who can I fix this error?

hi, here are some point to consider maybe it might help
1-check the baud rate , the library is made to use 9600 your module might use different one, mine uses 155200
2-if you are using tx0 and rx0 disconnect the cable while uploading the code.
3-connect the esp8266 ground to the arduino board ground ' i do not know why this works ' :)
4-is CH-PD pin of esp set to high 3.3v ??
