i use the wifi module and arduino mega 2560, and i try to test the http protocol --the get methods (from the Arduino Playground - WebClient)
I do as following. 1.i connect the wifi to my router (it is OK, i can ping the wifi module)
2.i change my data in the example.
the problem shows as following, i am puzzled where should i check?
avrdude: stk500v2_ReceiveMessage():timeout
Too little information. Which WiFi module (there are several)? How do you communicate with the WiFi module (SPI, SoftwareSerial, or Serial)?
If (as I suspect from the error) it is Serial you need to disconnect the WiFi module while you are uploading a new sketch to your Mega. Otherwise the WiFi module is also responding to the communication between avrdude and the 2560 confusing everyone in the process.
