The application is running on Cortex M3 micro-controller. And it has 64k RAM size, out of this my application hardly takes 10k RAM(not considering lwip RAM size). After going through the code i found that for receiving it uses PBUF_POOL as well as PBUF_RAM. But while transmitting it uses PBUF_RAM only and PBUF_RAW is used as pbuff_layer. My requirement is large size of file transmission & reception simultaneously which i m not able to achieve. Please suggest suitable lwip configuration for my application. Asma.
