ESP8266 Community Forum

- Thu Sep 24, 2015 9:12 am #29780 Hello. I am using ESP8266 for my project. But i have problem. When i send data by manual this is good very well. But when i do the same step by step but use TM4C123 i have 400 Bad Request. i think problem from \n\r. Here is my code in C.

UARTprintf("GET /channels/24430/feeds/last?key=MUIUX8IZ5YNT0OTG");
UARTprintf("\r\n");
any one met this case before plese help.
Thank a lot.

Code: Select allUARTprintf("GET /channels/24430/feeds/last?key=MUIUX8IZ5YNT0OTG HTTP/1.1\r\n");
UARTprintf("Host: thehostname.com\r\n");
UARTprintf("\r\n");
