Set the number of WiFi dynamic RX buffers, 0 means unlimited RX buffers will be allocated
|
|
(provided sufficient free RAM). The size of each dynamic RX buffer depends on the size of
|
|
the received data frame.
|
|
|
|
For each received data frame, the WiFi driver makes a copy to an RX buffer and then delivers
|
|
it to the high layer TCP/IP stack. The dynamic RX buffer is freed after the higher layer has
|
|
successfully received the data frame.
|
|
|
|
For some applications, WiFi data frames may be received faster than the application can
|
|
process them. In these cases we may run out of memory if RX buffer number is unlimited (0).
|
|
|
|
If a dynamic RX buffer limit is set, it should be at least the number of static RX buffers.

ESP-MESH utilizes beacon frames to detect and resolve root node conflicts (see documentation). However the
|
|
default length of a beacon frame can simultaneously hold only five root node identifier structures,
|
|
meaning that a root node conflict of up to five nodes can be detected at one time. In the occurence of
|
|
more root nodes conflict involving more than five root nodes, the conflict resolution process will detect
|
|
five of the root nodes, resolve the conflict, and re-detect more root nodes. This process will repeat
|
|
until all root node conflicts are resolved. However this process can generally take a very long time.
|
|
|
|
To counter this situation, the beacon frame length can be increased such that more root nodes can be
|
|
detected simultaneously. Each additional root node will require 36 bytes and should be added ontop of the
|
|
default beacon frame length of
|
|
752 bytes. For example, if you want to detect 10 root nodes simultaneously, you need to set the beacon
|
|
frame length as
|
|
932 (752+36*5).
|
|
|
|
Setting a longer beacon length also assists with debugging as the conflicting root nodes can be identified
|
|
more quickly.
