help
|
|
If this feature is enabled, then all traffic from layer2(WIFI Driver)
|
|
to layer3(LWIP stack) will make a copy, the layer2 buffer will be
|
|
freed and the copy will be sent to layer3. Please be notified that the
|
|
total layer2 receiving buffer is fixed and ESP32 currently supports 25
|
|
layer2 receiving buffer, when layer2 buffer runs out of memory, then the
|
|
incoming packets will be dropped in hardware. The layer3 buffer is
|
|
allocated from the heap, so the total layer3 receiving buffer depends
|
|
on the available heap size, when heap runs out of memory, no copy will
|
|
be sent to layer3 and packet will be dropped in layer2. Please make sure
|
|
you fully understand the impact of this feature before enabling it.

Sockets take up a certain amount of memory, and allowing fewer
