If that's not an option then you will need to do as you are and wait for buffers to be freed when ACKs arrive. To get ACKs more quickly I would suggest using a small TCP_MSS value. cristo hipercubicoSpletlwIP pbuf_alloc failure. Appreciate your help for LWIP newbie.

The default initialization of the physics buffer (pbuf) fields is to set. them to the nan value accessed from the infnan module (this is done in the. pbuf_allocate subroutine in phys_buffer.F90). Below is sample code that illustrates the basics of how physics buffer. fields are set. The sample shows how to initialize a pbuf ... SpletThe differences between a pbuf chain and a packet queue are very precise but subtle. The last pbuf of a packet has a ->tot_len field that equals the ->len field. It can be found by traversing the list. If the last pbuf of a packet has a ->next field other than NULL, more packets are on the queue.
