GET /update?api_key doesn't return anything

[squalo]

Hi,

i am using ESP8266 with STM32F4. I am trying to send data to thingspeak using

Code: Select all

GET /update?api_key

command. I have to see

Code: Select all

>

in my buffer before use

Code: Select all

GET /update?api_key

command. And i can see

Code: Select all

>

in my buffer. Then, i use these lines to send data:

Code: Select all

sprintf(gidecekdeger,"GET /update?api_key=A0AISRD6SB8SKH4J&field1=%d\r\n",10);

HAL_UART_Transmit(&huart2, (uint8_t *)gidecekdeger,strlen(gidecekdeger), 500);


but these lines returns nothing. (i put a breakpoint, so i am sure that code reaches here)

where is my mistake?
