Why is a simple GET failing with protocol error?
Hi, I am trying to do a simple GET request:
sample
pc.baud(115200);
eth.init(); //Use DHCP
eth.connect();
pc.printf("IP Address is %s\n", eth.getIPAddress());
//GET data
pc.printf("\nTrying to fetch page...\n");
int ret = http.get("http://developer.mbed.org/media/uploads/donatien/hello.txt", str, 256);
if (!ret)
{
pc.printf("Page fetched successfully - read %d characters\n", strlen(str));
pc.printf("Result: %s\n", str);
}
else
{
pc.printf("Error - ret = %d - HTTP return code = %d\n", ret, http.getHTTPResponseCode());
}
But it's failing with error code 3 (protocol error). Response code is 200.
This is on Freescale FRDM-K64F.
What am I doing wrong?

I also had problems with this, it was the buffer size for the URL, this was 32 chars. So it failed for any URLs bigger, there is a note about this somewhere. Have a look at my test program (also K64F) and you can see the simple edits I made to the HTTPClient library (look for buf_size) http://developer.mbed.org/users/colinmeikle/code/weather/ and http://developer.mbed.org/users/colinmeikle/code/HTTPClient/file/a0d9edb403e5/HTTPClient.cpp
