[lwip-users] why the program blocks on tcpip_apimsg when the network is broken

[yangjinwei82]

Hi all,

I'm porting lwIP v1.3.0 on the Set-Top Box. It's application connects to a server using TCP and calls the function netconn_send() to send data. When the network link is broken, the application sends some data to the server all the same,then it's blocked on tcpip_apimsg() which is called by netconn_send(). Could you tell me why the application is blocked when the network is broken and how to modified it?

Thank you very much for any help.

Best wishes for you.
