Keil TCPnet error "Map_Socket, No Listen Socket found"

Filip Zalio

Hi, I'm running Keil TCPnet on a STM32F4 device via PPP. I'm getting the error message "TCP-ERR:Map_Socket, No Listen Socket found" occassionally. Has anyone seen it, and does anyone know what it means? There is no mention of it anywhere in the documentation.

Thanks.

    The error message means that TCP manager can not map received TCP packet to any open & listening socket. If you see this message occasionally (probably while using Web server), you should increase number of TCP sockets and number of HTTP sessions in the configuration.
