Hi,

I like to open simultaneously up to 30 TCP/IP connections on the XMC4500 (RelaxKit). The only limits I could find in LWIP are the mailbox sizes (e.g. #define TCPIP_MBOX_SIZE 😎
but I assume this is just a queue size. Does anyone know if it creates stability problems (e.g. due to memory usage) if that many TCP/IP connections are kept open at once?

Thank you

Hi,

It should not create any stability problems. You can change the number of simultaneously TCP connections using MEMP_NUM_TCP_PCB. But of course it will require more memory.

Best Regard,
