I'm trying to provide a server connection to 2 clients on ports 1024 and 1025 using LWIP raw API. I have created two separate pcbs and can listen on both ports successfully, but writing to either pcb results in data being sent to the first pcb only;
//initialize connections to Ports 1024 and 1025
void Eth_Init(){
pcb_out1 = tcp_new();
tcp_bind(pcb_out1, IP_ADDR_ANY , 1024);
pcb_in1 = tcp_listen(pcb_out1);
tcp_accept(pcb_in1,connection_accept1);
pcb_out2 = tcp_new();
tcp_bind(pcb_out2, IP_ADDR_ANY , 1025);
pcb_in2 = tcp_listen(pcb_out2);
tcp_accept(pcb_in2,connection_accept2);
}
//attempt to write to both ports but 1024 receives the str twice?
void Eth_Write_String(char *str){
tcp_write(pcb_out1, str, strlen(str), TCP_WRITE_FLAG_COPY);
tcp_output(pcb_out1);
tcp_write(pcb_out2, str, strlen(str), TCP_WRITE_FLAG_COPY);
tcp_output(pcb_out2);
}
Any help is appreciated...
