I have an Aquarium control Project. I’m using Arduino Mega and ESP8266 and Blynk I want to load my codes but I’m taking error messages. how can I solve it ?
warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed
espcomm error is well documented on the Arduino forums.
Can be a whole host of things like port already open in another program, wrong baud rates, temporary failure etc.
Start by posting your formatted sketch as bad code will give espcomm errors.
