I want to send a GET request to a server, so I connected the microcontroller (STM32) with an Ethernet module, as the microcontroller does not have a built-in Ethernet feature. I am using these two libraries: #include "stm32f4xx_hal_uart.h" and #include "stm32f4xx_hal.h". My GET string is:

char http_get_request[] = "GET /testX HTTP/1.1\r\nHost: IP addressort\r\n\r\nUser-Agent: Mozilla/4.0\r\nAccept: /\r\nAccept-Encoding: gzip, deflate, br\r\nConnection: keep-alive\r\n";

However, I face an issue when debugging the program: "Break at address '0xe' with no debug information available, or outside of program code." The number '0xe' changes repeatedly when I try to debug the program again and again (0x0, 0x10, 0xfceaf000). Could anyone help me resolve this error? Thanks in advance.

 

Welcome to AAC.

What are you doing with http_get_request? That is, how are you trying to send it?
How have you set up the TCP/IP stack? You have provided almost no information.
