SOCKETS_inet_ntoa This macro converts an IP address that is expressed as a 32-bit number in network byte order to a string in decimal-dot notation.Usage restrictions Only TCP sockets are supported by the FreeRTOS Secure Sockets library. UDP sockets are not supported.Server...

But I forgot wrap serv_addr.sin_addr.s_addr in inet_ntoa() - it isn't string, but integer. This caused access to invalid memory address which was just server's IP (the number 0x201A8C0 stored in BFAR is 192.168.1.2 - address of my server if you reverse the bytes order and ...
