I've got an STM32F7 (SPL, not HAL) based project using LwIP RAW. We've got it working fairly well, but it seems to handle 6 UDP packets very quickly and then start dropping packets. I thought it was because of the MEMP_NUM_UDP_PCB which was defined as 6, but increasing it to 12 has had no effect.
Can you make any other recommendations as to how to increase our throughput?
Thank you,
Luciano
