Hello, All.
I try to use LwIP (oh... 1.4.1) for embedded, tcp client in callback mode. Stream is 128000 bytes /sec, MCU has 200 kiB memory total.
I have wrote code, it started ok. But it stops after some time with message
> memp_malloc: out of memory in pool PBUF_POOL
I tried find problem, tcp_pcb -> unacked grows before stop.
How to tell LwIP resend unacked data? How to check filled / awailable PBUFs total? How to set timeout for ACK (which value of lwipopts.h )?
PS: LwIP send usually about 10..18 MiB before stop.
