Hello, I'm trying to make a server which responds to a client. The server responds to certain commands. Each client is handled in a seperate task. When a client disconnect from the server, without prior notice, the server crashes. I think it has something to do that the receivetask tries to read the data from the netconn, but the netconn is getting closed after the check. When I receive a disconnect command, I delete the tasks first, and the netconn after. Then there aren't any problems.
I do a check before reading the data like this: ************************** if (rcvSocket->pcb.tcp->state > ESTABLISHED) return -1; netconn_recv(rcvSocket, &rcvBuff); //Move the data to a local buffer //Return ************************** Using the netconn::state doesn't work either for this check I couldn't figure any way to safely read data. The transmit task doesn't seem to give any problems tough. Is there anyone who might have a solution? I'm using FreeRTOS V8.0.1 and LWIP v1.4.1 <http://lwip.100.n7.nabble.com/file/n23118/Drawing1.png> Thanks in advance Cheers!
