Re: [lwip-users] Limiting the number of connections: Possible bug with MEMP_NUM_TCP_PCB?

So, I found the problem on my end: The initialization code was called twice... The first time when NETIF was UP, the second time when DHCP got an IP-address... (And the initialization the second time obviously was badly written and screwed up the list of lpcbs) I guess this behaved differently

Re: [lwip-users] Limiting the number of connections: Possible bug with MEMP_NUM_TCP_PCB?

And one more thing: In our app, when the network starts, the following code is how the listening is initialized. This was working OK in 1.3.2, but I suspect this breaks 2.0.2 and could cause the problems I see now. Is this a correct way to initialize the listening connection, or is this code

One more observation from a debugging session (with n=2) with these settings #define MEMP_NUM_TCP_PCB2 #define MEMP_NUM_TCP_PCB_LISTEN 2 (Hex numbers are addresses of pcbs or lpcbs) Two listening lpcb initially: 0xb78c 0xb76c The first two connections use the following
