I'm trying to upload a program on arduino uno with esp8266 and a bunch of sensors to send data on a website. I get to compile the program successfully but when I upload it, the ff error message appears:

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x11

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x10
avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x44
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
this check.

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x10

I'm using arduino uno and my IDE is ver 1.6.5.

I'd appreciate some help. Thanks!

Also try reducing the upload speed on the ESP board selector screen. Make sure that GPIO 0 is tied to ground and GPIO 2 is pulled high, ideally with a 10 K resistor.

You do not say which ESP 8266 you have or how it is adapted, if at all, via a break out board. It is difficult to help without knowing your set up.
Anyway god luck!
