The datasheet says “Supports 8 independent sockets simultaneously”. What exactly this mean? Does it mean that I can only have 8 TCP/IP connections simultaneously? Can you elaborate the mentioned sentence please?
That’s exactly what it means. On the bright side, the hardware manages the SYN/ACK process on listening sockets to establish a connection without software intervention, but on the down side you’re limited to 8 simultaneous network connections (TCP and/or UDP).
"Supports 8 independent sockets simultaneously” mean you can use 8 kinds of application.
